This page will contain news stories about daylight saving time, as they become available.Daylight saving timeDaylight saving time (also called DST) is a term used for a system intended to "save" daylight (It is also known as summer time in both Britain and Europe). The official time is adjusted forward, (usually) one hour from its official standard time, remaining that way for the duration of the spring and summer months. This is intended to provide a better match between the hours of daylight and the active hours of work and school. DST is most commonly used in temperate regions, due to the considerable variation in the amount of daylight versus darkness through the seasons in those regions. Note that the term commonly used in the United States, daylight savings time, is incorrect, for both historic (the correct name as provided by the act which inaugurated it in the United States is daylight saving time) and grammatical reasons. OriginIt is sometimes asserted that DST was first proposed by Benjamin Franklin in a letter to the editors of the Journal of Paris. (Read the full text.) However, the article was humorous; Franklin was not proposing DST, but rather that people should get up and go to bed earlier. It was first seriously proposed by William Willett in the "Waste of Daylight", published in 1907, but he was unable to get the British government to adopt it despite considerable lobbying. The idea of daylight saving time was first put into practice by the German government during the First World War between April 30 and October 1, 1916. Shortly afterward, the United Kingdom followed suit, first adopting DST between May 21 and October 1, 1916. Then on March 19, 1918, the U.S. Congress established several time zones (which were already in use by railroads and most cities since 1883) and made daylight saving time official (which went into effect on March 31) for the remainder of World War I. It was observed for seven months in 1918 and 1919. The law, however, proved so unpopular (mostly because people rose and went to bed earlier than in current times) that the law was later repealed. Observation of DSTDaylight saving time is generally a temperate zone practice; day lengths in the tropics do not vary enough to justify DST. Hawaii, the only U.S. state in the tropics, does not observe DST. The amount of the time shift varies, but one hour is the most common. The dates of the beginning and ending of DST also vary by country. With a few exceptions, switchovers between standard time and daylight saving time generally occur in the early morning hours of a Sunday morning, presumably because doing so then causes less disruption than a change on a weekday would. DST commonly begins in the Northern Hemisphere on either the first Sunday in April or the last Sunday in March, and ends on the last Sunday in October. In the Southern Hemisphere, the beginning and ending dates are switched (thus the time difference between, e.g., the United Kingdom and Chile may be three, four, or five hours). Usage and history by locationAfricaEgyptEgypt operates Daylight-Saving Time between the last Friday in April and the last Thursday in September when the clocks are 3 hours ahead of Greenwich Mean Time (GMT+3). AsiaChinaThe People's Republic of China experimented with DST from 1986, but abandoned it in the 1990s. The PRC now uses one universal time zone for all of the nation from Urumqi in the northwest to Fujian in the southeast; the size of the nation was a major factor why DST was not considered practical in China. IndiaIndia used DST briefly during its wars with Pakistan and China. IranIran uses the Persian calendar. Thus, DST in Iran starts on the first day of Farvardin (around 21-22 March) and ends on the first day of Mehr (around 22 September). IsraelIsrael adopts Daylight Saving Time on the last Friday before April 2 at 02:00, and returns to standard time at 02:00 of the Sunday of the month of Tishrei between Rosh Hashanah and Yom Kippur. Israel's Daylight Saving Time rules have changed repeatedly in recent years; there has been trouble reaching a consensus regarding Gregorian calendar end dates for DST as they are dependant on Jewish Holidays, which follow the lunar Hebrew calendar. For more on this subject, see Israeli Daylight Saving Law. PakistanPakistan experimented with DST in 2002 going from +5:00 to +6:00. It has not used DST since then. AustralasiaAustraliaIn Australia, daylight saving time is a state/territory-based initiative. Some states/territories implement it and some do not. New South Wales, Victoria, Tasmania, Australian Capital Territory and South Australia apply daylight saving time. Tasmania starts DST earlier than the others, usually near the beginning of October. Western Australia, Northern Territory and Queensland do not have daylight saving. Queensland experimented with it for a year or two in the early 1970s, but it was not popular and was abandoned. See the Australian time zones article or this site for maps and further information on standard and daylight saving time in Australia. New ZealandIn New Zealand, daylight saving time begins at 2am (standard time) on the first Sunday in October each year, and ends at 2am (standard time) on the third Sunday of March. The Department of Internal Affairs gives further historical information on their website. EuropeAll countries in Europe, except Iceland as noted below, observe daylight-saving time and change on the same date: moving clocks forward one hour on the last Sunday in March and back one hour on the last Sunday in October. In the West European (UTC), Central European (UTC+1), and East European (UTC+2) time zones the change is simultaneous: on both dates the clocks are changed everywhere at 01:00 UTC, i.e. from local times of 01:00/02:00/03:00 to 02:00/03:00/04:00 in March, and vice versa in October. (See also: European Summer Time). In Russia, however, although the changeover dates are the same, clocks are moved forward or back at 02:00 winter time in all zones. Thus in Moscow (local time = UTC+3 in winter, UTC+4 in summer), daylight-saving time commences at 23:00 UTC on the day before the last Sunday in March, and ends at 23:00 UTC on the day before the last Sunday in October. IcelandWith Iceland observing UTC all year round, despite being at a longitude which would indicate UTC-1, the country may be said to be on continuous DST. Polar or near-polar locations such as Iceland often opt out, as summer in these locations usually brings nearly uninterrupted daylight. North AmericaNorth America generally follows the same procedure, going by local time in each zone, each time zone switching at 02:00 LST (local standard time) to 03:00 LDT (local daylight time) on the first Sunday in April, and again from 02:00 LDT to 01:00 LST on the last Sunday in October. In 2007, the starting and ending dates for DST will change in the United States and parts of Canada (see below). The Canadian province of Newfoundland and Labrador is an exception in that the time changes take place at 00:01 local standard time and 00:01 local daylight time respectively. Also, in 1988, they experimented with Double Daylight Time, when the clocks went ahead by two hours, instead of the usual one hour. CanadaIn Canada, time is under provincial and territorial jurisdiction, not federal. The governments of Ontario, Manitoba, Quebec, and Alberta have pledged to change their daylight saving rules to match the new U.S. rules (The Calgary Sun). In 2007, their DST will start on the second Sunday of March, and return to standard time on the first Sunday in November. The remaining provinces and territories will continue change time on the first Sunday of April and last Sunday of October unless they change their legislation. The province of Saskatchewan is the largest part of that country that does not use DST, that is, it does not adjust clocks in spring and fall. Saskatchewan is bisected by 105° west meridian, the central meridian of the Mountain Standard Time Zone (UTC−7), yet clocks are kept at UTC−6 all year long. (This policy was implemented when the Saskatchewan Time Act was passed in 1966, to solve the problems that arose when time zones varied from town to town.) Thus, in the summer months Saskatchewan is in sync with Mountain Daylight Time and in the winter months it is in sync with Central Standard Time. Observationally, this is equivalent to the province being on Mountain Daylight Time year-round, though officially the province is considered to be part of the Central time zone. The charter of the city of Lloydminster, which is bisected by the Saskatchewan–Alberta border, gives it a special exception (among areas in Saskatchewan) to use DST. Lloydminster and its immediately surrounding region in Saskatchewan use the same timekeeping routine used by Alberta, DST with Mountain Standard Time. Saskatchewan Government Relations gives further details on Saskatchewan's time policies. CubaCuba always starts its DST on April 1 but the end date varies. Since April 2004, Cuba has remained on DST. MexicoMexico has adopted DST nationwide, even in its tropical regions, because of its increasing economic ties to the United States. The Mexican state of Sonora does not observe DST because it borders on the U.S. state of Arizona, which also does not observe DST. United StatesThrough the end of 2006, the United States starts its DST on the first Sunday in April, and changes back to standard time on the last Sunday in October. Beginning in 2007, it will start DST on the second Sunday in March, and change back to standard time on the first Sunday in November. Daylight saving time was reinstated in the United States on February 9, 1942, again as a wartime measure to conserve resources. This remained in effect until World War II began winding down and the requirement was removed on September 30, 1945. From 1945 to 1966, U.S. federal law did not address daylight saving time. States and localities were free to observe daylight saving time or not. This resulted in a patchwork where some areas observed DST while adjacent areas did not, and it was not unheard of to have to reset one's clock several times during a relatively short trip (e.g., bus drivers operating between Moundsville, West Virginia, and Steubenville, Ohio had to reset their watches seven times over 35 miles). The U.S. federal Uniform Time Act of 1966 mandated that daylight saving time begin nationwide on the last Sunday of April and end on the last Sunday of October. Any state that wanted to be exempt from daylight saving time could do so by passing a state law, provided that it exempt the entire state. The law was amended in 1972 to permit states that straddle a time zone boundary to exempt the entire area of the state lying in one time zone. The law was amended again in 1986 to begin daylight saving time on the first Sunday in April, to take effect the following year. In response to the 1973 energy crisis, daylight saving in the United States was begun earlier in both 1974 and 1975, commencing on the first Sunday in January (January 6) in the former year and the last Sunday in February (February 23) in the latter. Starting March 11, 2007, daylight saving time will be extended another four to five weeks, from the second Sunday of March to the first Sunday of November. The change was introduced by the Energy Policy Act of 2005; the House had originally approved a motion that would have extended DST even further. Proponents claimed that the extension would save "the equivalent of" 10,000 barrels of oil per day, but this figure was based on U.S. Department of Energy information from the 1970s, the accuracy and relevance of which the DoE no longer stands by. There is very little recent research on what the actual positive effects, if any, might be. (See this article, for example.) The extension was greeted by criticism from the airline industry and those concerned for the safety of children traveling to school in the dark before the late sunrise. An additional issue raised by this extension is that it requires reconfiguration of virtually every computer in the United States. Most computers are programmed to adjust automatically for DST, but they do so based on static tables stored directly on the computer itself. In order to change the dates and times at which the automatic jump to or from DST occurs, these tables must be modified, which requires some sort of manual intervention by a human being in the great majority of cases. A two-minute procedure for updating a computer, multiplied by a hundred million computers, represents nearly 1700 years of full-time labor. More difficult to quantify is the amount of labor and money that may be spent correcting errors that arise due to a failure to update computers. Certain types of information systems (those that schedule future events with reference to UTC, for example) are almost guaranteed to encounter serious desynchronization problems unless both computers and databases are carefully updated—in some cases by hand. ArizonaMost of Arizona does not observe DST. However, the large Navajo Indian Reservation within it does. HawaiiHawaii does not observe DST. IndianaDST has been a long-standing controversy in Indiana, not only as an agricultural state, but also because the border separating the Eastern and Central time zones divides the state. In the past, neighboring communities sometimes ended up one or even two hours apart. Being out of sync with neighboring states and the national changing of clocks, supporters argued, had a negative economic impact on the state. Some supporters claimed that some businesses had located out-of-state due to the time-related confusion. Opponents claimed that daylight saving time created costs and inconvenience associated with changing clocks twice a year and had little or no real value. From 1991 until April 1, 2006 the state had three kinds of time zones and DST observances:
On April 29, 2005, the Indiana legislature voted to begin observing daylight saving time statewide in 2006. The bill to observe DST also required the governor to request federal review of the time zone divisions in the state. As a result of the review, the United States Department of Transportation moved eight more counties to the Central time zone, effective when DST begins on April 2, 2006. These counties are: Starke and Pulaski Counties in the Northwest, and Daviess, Dubois, Knox, Martin, Perry, and Pike in the Southwest. Currently, Pulaski and Martin counties are reconsidering their bid to join the Central time zone. Standard Time Zone Boundary in the State of Indiana (a 139 KB pdf file) has some history, public comments from each county, the final DOT determination, and the resulting time zone boundary. South AmericaChileChile switches to DST at 24:00 on the second Saturday in October and reverts to Local Standard Time (LST) at 24:00 on the second Sunday the following March. The current law which affects the entire country was enacted in 1970, but it had observed the practice as early as 1927 when the country had been divided into two distinct time zones. In specific years the starting and ending dates have been modified for political or climatic reasons. BrazilBrazil adopted DST for the first time in 1931, but uninterruptedly since 1985 in southern states (south, southeast regions and states of Goiás and Mato Grosso do Sul). Starting and ending dates are variable: normally, Brazilian DST starts at 00:00 on an October (rarely November) Sunday and ends at 00:00 on a February Sunday. Rationales for DSTOne of the major reasons given for observing DST is energy conservation. Theoretically, the amount of residential electricity needed in the evening hours is dependent both on when the sun sets and when people go to bed. Because people tend to observe the same bedtime year-round, by artificially moving sunset one hour later, the amount of energy used is theoretically reduced. United States Department of Transportation studies showed that DST reduces the country's electricity usage by one percent while DST is in effect. Part of the reason that it is normally observed in the late spring, summer, and early autumn is because during the winter months the amount of energy saved by moving sunset one hour later is negated by the increased need for morning lighting by moving sunrise by the same amount. During the summer most people would wake up after the sun rises, regardless of whether daylight saving time is in effect or not, so there is no increased need for morning lighting to offset the afternoon drop in energy usage. Another perceived benefit of DST is increased opportunities for outdoor activities. Most people plan outdoor activities during the increased hours of sunlight. Other benefits cited include prevention of traffic injuries (by allowing more people to return home from work or school in daylight), and crime reduction (by reducing people's risk of being targets of crimes that are more common in dark areas). When the U.S. went on extended DST in 1974 and 1975 in response to the 1973 energy crisis, Department of Transportation studies found that observing DST in March and April saved 10,000 barrels of oil a day, and prevented about 2,000 traffic injuries and 50 fatalities saving about U.S. $28 million in traffic costs. (Stats from this article). Criticism of DSTDST is not universally accepted; many localities do not observe it. Opponents claim that there is not enough benefit to justify the need to adjust clocks twice every year. The disruption in sleep patterns associated with setting clocks either forward or backward correlates with a spike in the number of severe auto accidents, as well as lost productivity as sleep-disrupted workers adjust to the schedule change. It is also noted that much effort is spent reminding everyone twice a year of the change, and thousands are inconvenienced by showing up at the wrong time when they forget. There is also a question whether the decrease in lighting costs justifies the increase in summertime air conditioning costs. While many people use more sunlight under DST, most people also experience more heat, which prompts many people to turn on the air conditioner during the warmer afternoon hours. When air conditioning was not widely available, the change did save energy; however, air conditioning is much more widespread now than it was several decades ago. Air conditioning often uses more energy than artificial lighting. It was for this reason that Arizona rejected DST and opted to stay on standard time all year. It is also speculated that one of the benefits—more afternoon sun—would also actually increase energy consumption as people get into their cars to enjoy more time for shopping and the like. No formal studies have been performed, but an enormous amount of time has been spent by software developers to deal with the fact that 2400 hours past 2pm is not necessarily 2pm 100 days later. For example, during a North American time change, an autumn night where clocks are reset from 3 AM summer to 2 AM winter time, times between 2AM and 3AM will occur twice, causing confusion in transport schedules, payment systems, etc. Some studies do show that changing the clock increases the traffic accident rate.[1] Following the spring shift to daylight saving time (when one hour of sleep is lost) there is a measurable increase in the number of traffic accidents that result in fatalities. Some campaigners in Britain would like the country to stay on British Summer Time (BST) all year round, or in other words, adopt Central European Time and abolish BST. Alternatively, some would like Britain to adopt Central European Time and jump forward another hour during the summer (adopting a Single/Double Summer Time from Britain's perspective). This would make winter evenings longer, thereby reducing traffic accidents and cases of seasonal affective disorder. Opponents point to the longer hours of darkness on winter mornings, especially in Scotland, the north of England and Northern Ireland which might well cause an increase in road accidents. DST is particularly unpopular among people working in agriculture because the animals do not observe it, and thus the people are placed out of synchronization with the rest of the community, including school times, broadcast schedules, and the like. Other critics suggest that DST is, at its heart, government paternalism and that people rise in the morning as a matter of choice because many people enjoy nighttime hours and their jobs do not require them to make the most of daylight. Different people start their day at different times (office workers start their day later than factory workers, who start their day later than farm workers), regardless of daylight saving time. MnemonicThe mnemonic "spring forward, fall back" tells us how to reset clocks when the time changes, regardless of hemisphere (although it has to be remembered that spring and autumn occur during different months in the northern and southern hemispheres). This uses the word "fall" to mean "autumn"; while this usage has died out in British English, it is still very common in North American English. Another common mnemonic of equal meaning is "spring ahead, fall behind." Associated practicesFire safety officials in Australia, Canada, New Zealand, and the United States encourage citizens to use the two annual time changes as a reminder to check the batteries in home and office fire alarms and smoke detectors. For example, the Country Fire Authority of Victoria in Australia has been running a program called "Change Your Clock, Change Your Smoke Alarm Battery" for several years. This is especially important in autumn, just before the heating season causes an increase in home fires. The nameIn the standard form of the name, "daylight saving" is a compound adjective (part of which is a participle) that modifies "time." A common variant is daylight savings time. Although this alternate form is frequently heard in speech, it is nonstandard and appears rarely in edited writing. Most compound adjectives are joined with a hyphen, but "daylight-saving time," too, is nonstandard. Nevertheless, the form "daylight savings time" appears without remark as to its nonstandardness in some dictionaries, including The American Heritage Dictionary. Notes

Nevertheless, the form "daylight savings time" appears without remark as to its nonstandardness in some dictionaries, including The American Heritage Dictionary. The islanders' African heritage has also played an influential role in many aspects of Grenada's culture. Most compound adjectives are joined with a hyphen, but "daylight-saving time," too, is nonstandard. Soca, calypso, and reggae set the mood for Grenada's annual Carnival activities. In the standard form of the name, "daylight saving" is a compound adjective (part of which is a participle) that modifies "time." A common variant is daylight savings time. Although this alternate form is frequently heard in speech, it is nonstandard and appears rarely in edited writing. Music, dance, and festivals are also extremely important. This is especially important in autumn, just before the heating season causes an increase in home fires. Foods aren't the only important aspect of Grenadian culture. For example, the Country Fire Authority of Victoria in Australia has been running a program called "Change Your Clock, Change Your Smoke Alarm Battery" for several years. Island culture is heavily influenced by the African roots of most of the Grenadians but Indian influence is also seen with Dhal Puree, Goat and Chicken curry in the cuisine. Fire safety officials in Australia, Canada, New Zealand, and the United States encourage citizens to use the two annual time changes as a reminder to check the batteries in home and office fire alarms and smoke detectors. Although French influence on culture is much less than in other Caribbean islands, surnames and place names in French remain and some French architecture has survived from the 1700s. Another common mnemonic of equal meaning is "spring ahead, fall behind.". Main article: Culture of Grenada. This uses the word "fall" to mean "autumn"; while this usage has died out in British English, it is still very common in North American English. There is a small Muslim population mostly from old Iraqui immigrants who came many years ago and set up some merchant shops. The mnemonic "spring forward, fall back" tells us how to reset clocks when the time changes, regardless of hemisphere (although it has to be remembered that spring and autumn occur during different months in the northern and southern hemispheres). Most Churches have demonination based schools but are open to all. Different people start their day at different times (office workers start their day later than factory workers, who start their day later than farm workers), regardless of daylight saving time. Aside from a marginal community of Rastafarians living in Grenada, nearly all are Christians, about half of them Catholics; Anglicanism is the largest Protestant denomination with Presbyterian and Seventh Day Adventist taking up the remainder. Other critics suggest that DST is, at its heart, government paternalism and that people rise in the morning as a matter of choice because many people enjoy nighttime hours and their jobs do not require them to make the most of daylight. The official language, English, is spoken by virtually everyone, although all locals can still speak a French-English Creole language called Patois) still used on St Vincent, Dominica and St Lucia . DST is particularly unpopular among people working in agriculture because the animals do not observe it, and thus the people are placed out of synchronization with the rest of the community, including school times, broadcast schedules, and the like. This means that probably around a third of those born in Grenada still live there. Opponents point to the longer hours of darkness on winter mornings, especially in Scotland, the north of England and Northern Ireland which might well cause an increase in road accidents. Popular migration points for Grenadians further north include New York City, Toronto, London and Yorkshire. This would make winter evenings longer, thereby reducing traffic accidents and cases of seasonal affective disorder. With less than 100,000 people living in Grenada, estimates and census data suggest that there are at least that number of Grenadian-born people in other parts of the Caribbean (such as Barbados and Trinidad) and at least that number again in 'first world' countries. Alternatively, some would like Britain to adopt Central European Time and jump forward another hour during the summer (adopting a Single/Double Summer Time from Britain's perspective). Grenada, like many of the Caribbean islands is subject to a large amount of migration, with a large amount of young people wanting to leave the island to seek life elsewhere. Some campaigners in Britain would like the country to stay on British Summer Time (BST) all year round, or in other words, adopt Central European Time and abolish BST. Lucia and Grenada which started in 1855 with the rest of a mixture of African Indian and European descent. Some studies do show that changing the clock increases the traffic accident rate.[1] Following the spring shift to daylight saving time (when one hour of sleep is lost) there is a measurable increase in the number of traffic accidents that result in fatalities. About 12% are descendants of the Indian indentured emigration to St. For example, during a North American time change, an autumn night where clocks are reset from 3 AM summer to 2 AM winter time, times between 2AM and 3AM will occur twice, causing confusion in transport schedules, payment systems, etc. About 80% of the population are descendants of the African slaves brought by the Europeans; no indigenous Carib and Arawak population survived the French purge at Sauteurs. No formal studies have been performed, but an enormous amount of time has been spent by software developers to deal with the fact that 2400 hours past 2pm is not necessarily 2pm 100 days later. Main article: Demographics of Grenada. It is also speculated that one of the benefits—more afternoon sun—would also actually increase energy consumption as people get into their cars to enjoy more time for shopping and the like. It is found between the nutmeg fruit and the nut itself. It was for this reason that Arizona rejected DST and opted to stay on standard time all year. The red lacy material in the photo is mace. Air conditioning often uses more energy than artificial lighting. There is a nutmeg on the nation's flag. When air conditioning was not widely available, the change did save energy; however, air conditioning is much more widespread now than it was several decades ago. Cinnamon, cloves, ginger, mace, and nutmeg are important exports. While many people use more sunlight under DST, most people also experience more heat, which prompts many people to turn on the air conditioner during the warmer afternoon hours. Grenada is sometimes called spice island. There is also a question whether the decrease in lighting costs justifies the increase in summertime air conditioning costs. Grenada shares a common central bank and a common currency (the East Caribbean Dollar) with seven other members of the Organisation of Eastern Caribbean States (OECS). It is also noted that much effort is spent reminding everyone twice a year of the change, and thousands are inconvenienced by showing up at the wrong time when they forget. Major short-term concerns are the rising fiscal deficit and the deterioration in the external account balance. The disruption in sleep patterns associated with setting clocks either forward or backward correlates with a spike in the number of severe auto accidents, as well as lost productivity as sleep-disrupted workers adjust to the schedule change. Tourist facilities are being expanded; tourism is the leading foreign exchange earner. Opponents claim that there is not enough benefit to justify the need to adjust clocks twice every year. Economic progress in fiscal reforms and prudent macroeconomic management have boosted annual growth to 5%-6% in 1998-99; the increase in economic activity has been led by construction and trade. DST is not universally accepted; many localities do not observe it. Main article: Economy of Grenada. (Stats from this article). The most recent storms to hit have been Hurricane Ivan on September 7, 2004 causing severe damage and 39 deaths and Hurricane Emily on July 14, 2005 causing serious damge in Carriacou and in the north of Grenada which had been relatively lightly affected by hurricane Ivan. $28 million in traffic costs. Hurricane Janet passed over Grenada on 23 September 1955 with winds of 115 mph, causing severe damage. went on extended DST in 1974 and 1975 in response to the 1973 energy crisis, Department of Transportation studies found that observing DST in March and April saved 10,000 barrels of oil a day, and prevented about 2,000 traffic injuries and 50 fatalities saving about U.S. Grenada being on the southern edge of the hurricane belt has suffered only 3 hurricanes in 50 years. When the U.S. The climate is tropical: hot and humid in the rainy season and cooled by the trade winds in the dry season. Other benefits cited include prevention of traffic injuries (by allowing more people to return home from work or school in daylight), and crime reduction (by reducing people's risk of being targets of crimes that are more common in dark areas). Several small rivers with beautiful waterfalls flow into the sea from these mountains. Most people plan outdoor activities during the increased hours of sunlight. Catherine being the highest at 2,756 feet. Another perceived benefit of DST is increased opportunities for outdoor activities. Grenada's interior is very mountainous with Mount St. During the summer most people would wake up after the sun rises, regardless of whether daylight saving time is in effect or not, so there is no increased need for morning lighting to offset the afternoon drop in energy usage. The islands are of volcanic origin with extremely rich soil. Part of the reason that it is normally observed in the late spring, summer, and early autumn is because during the winter months the amount of energy saved by moving sunset one hour later is negated by the increased need for morning lighting by moving sunrise by the same amount. Largest settlement on the other islands is Hillsborough on Carriacou. United States Department of Transportation studies showed that DST reduces the country's electricity usage by one percent while DST is in effect. George's, Grenville and Gouyave. Because people tend to observe the same bedtime year-round, by artificially moving sunset one hour later, the amount of energy used is theoretically reduced. Most of the population lives on Grenada itself, and major towns there include the capital St. Theoretically, the amount of residential electricity needed in the evening hours is dependent both on when the sun sets and when people go to bed. The island Grenada itself is the largest island; smaller Grenadines are Carriacou, Petit Martinique, Rhonde Island, Caille Island, Diamond Island, Large Island, Saline Island and Frigate Island. One of the major reasons given for observing DST is energy conservation. Main article: Geography of Grenada. Starting and ending dates are variable: normally, Brazilian DST starts at 00:00 on an October (rarely November) Sunday and ends at 00:00 on a February Sunday. Carriacou and Petit Martinique, two of the Grenadines have the status of dependency. Brazil adopted DST for the first time in 1931, but uninterruptedly since 1985 in southern states (south, southeast regions and states of Goiás and Mato Grosso do Sul). Politically, Grenada is divided into six parishes:. In specific years the starting and ending dates have been modified for political or climatic reasons. Main article: Parishes of Grenada. The current law which affects the entire country was enacted in 1970, but it had observed the practice as early as 1927 when the country had been divided into two distinct time zones. Grenada is a full and participating member of both the Caribbean Community (CARICOM) and the Organisation of Eastern Caribbean States (OECS). Chile switches to DST at 24:00 on the second Saturday in October and reverts to Local Standard Time (LST) at 24:00 on the second Sunday the following March. The largest opposition party is the National Democratic Congress with 45.1% of the votes and 7 seats. Standard Time Zone Boundary in the State of Indiana (a 139 KB pdf file) has some history, public comments from each county, the final DOT determination, and the resulting time zone boundary. With 49.9% of the votes and 8 seats in the 2003 election, the New National Party remains the largest party in Grenada. Currently, Pulaski and Martin counties are reconsidering their bid to join the Central time zone. The senators are appointed by the government and the opposition, while the representatives are elected by the population for 5-year terms. These counties are: Starke and Pulaski Counties in the Northwest, and Daviess, Dubois, Knox, Martin, Perry, and Pike in the Southwest. The Parliament consists of a Senate (13 members) and a House of Representatives (15 members). As a result of the review, the United States Department of Transportation moved eight more counties to the Central time zone, effective when DST begins on April 2, 2006. Although appointed by the Governor General, the Prime Minister is usually the leader of the largest faction in the Parliament. The bill to observe DST also required the governor to request federal review of the time zone divisions in the state. Day-to-day executive power lies with the Head of Government, the Prime Minister. On April 29, 2005, the Indiana legislature voted to begin observing daylight saving time statewide in 2006. The Crown is represented by a Governor General, who is currently Sir Daniel Williams. From 1991 until April 1, 2006 the state had three kinds of time zones and DST observances:. As a Commonwealth Realm, Queen Elizabeth II is Queen of Grenada and Head of State. Opponents claimed that daylight saving time created costs and inconvenience associated with changing clocks twice a year and had little or no real value. Main article: Politics of Grenada. Some supporters claimed that some businesses had located out-of-state due to the time-related confusion. The agricultural industry and in particular the nutmeg industry suffered serious losses, but that event has begun changes in crop management and the nutmeg industry may be returning to its pre-Ivan position as a major supplier in the western world. Being out of sync with neighboring states and the national changing of clocks, supporters argued, had a negative economic impact on the state. By December 2005, 96% of all hotel rooms were to be open for business and to have been upgraded in facilities and strengthened to an improved building code. In the past, neighboring communities sometimes ended up one or even two hours apart. Grenada has recovered with remarkable speed, due to her climate and the resilience of her people combined with much needed help from her neighbours, and financing from the world at large. DST has been a long-standing controversy in Indiana, not only as an agricultural state, but also because the border separating the Eastern and Central time zones divides the state. This was much less damage than Ivan had caused. Hawaii does not observe DST. The following year, 2005, Hurricane Emily (July 14) struck the island, causing an estimated USD $110 million (EC$ 297 million) worth of damage. However, the large Navajo Indian Reservation within it does. The category 4 hurricane caused 90 percent of the homes to be damaged or destroyed. Most of Arizona does not observe DST. In 2004, the island after being hurricane free for 49 years, was directly hit by Hurricane Ivan (September 7). Certain types of information systems (those that schedule future events with reference to UTC, for example) are almost guaranteed to encounter serious desynchronization problems unless both computers and databases are carefully updated—in some cases by hand. The commission began shortly after the boys concluded their project. More difficult to quantify is the amount of labor and money that may be spent correcting errors that arise due to a failure to update computers. It also uncovered that there was still a lot of resentment in Grenadian society resulting from the era, and a feeling that there were many injustices still unaddressed. A two-minute procedure for updating a computer, multiplied by a hundred million computers, represents nearly 1700 years of full-time labor. Their project attracted a great deal of attention, including from the Miami Herald and the final report was published in a book written by the boys called Big Sky, Little Bullet. In order to change the dates and times at which the automatic jump to or from DST occurs, these tables must be modified, which requires some sort of manual intervention by a human being in the great majority of cases. George's tasked some of his senior students with conducting a research project into the era and specifically into the fact that Maurice Bishop's body was never discovered. Most computers are programmed to adjust automatically for DST, but they do so based on static tables stored directly on the computer itself. Brother Robert Fanovich, head of Presentation Brothers' College (PBC) in St. An additional issue raised by this extension is that it requires reconfiguration of virtually every computer in the United States. The commission was formed, bizarrely, because of a school project. The extension was greeted by criticism from the airline industry and those concerned for the safety of children traveling to school in the dark before the late sunrise. It held a number of hearings around the country. (See this article, for example.). The commission was chaired by a Catholic priest, Friar Mark Haynes, and was tasked with uncovering injustices arising from the PRA, Bishop's regime, and before. There is very little recent research on what the actual positive effects, if any, might be. In 2000-2002 much of the controversy of the late 1970s and early 1980s was once again brought into the public consciousness with the opening of the truth and reconciliation commission. Department of Energy information from the 1970s, the accuracy and relevance of which the DoE no longer stands by. These three countries could have militarily controlled the deep water passages, thereby controlling the movement of oil from Venezuela and Trinidad and Tobago (supplies then considered vital by US military planners). Proponents claimed that the extension would save "the equivalent of" 10,000 barrels of oil per day, but this figure was based on U.S. However, it should be noted that the island of Grenada could have become a corner of a triangle comprised also of Cuba and Nicaragua, both also declared enemies of US interests at that time. The change was introduced by the Energy Policy Act of 2005; the House had originally approved a motion that would have extended DST even further. George's University. Starting March 11, 2007, daylight saving time will be extended another four to five weeks, from the second Sunday of March to the first Sunday of November. nationals enrolled at St. In response to the 1973 energy crisis, daylight saving in the United States was begun earlier in both 1974 and 1975, commencing on the first Sunday in January (January 6) in the former year and the last Sunday in February (February 23) in the latter. A publicised tactical concern of the United States was the safe recovery of U.S. The law was amended again in 1986 to begin daylight saving time on the first Sunday in April, to take effect the following year. The forces quickly captured the ringleaders and hundreds of Cuban "advisors" (most of whom were labourers working on the construction of a major airport for the island, which the British completed a year later). The law was amended in 1972 to permit states that straddle a time zone boundary to exempt the entire area of the state lying in one time zone. Although the Governor-General, Sir Paul Scoon later stated that he had requested the invasion, the governments of the United Kingdom and Trinidad and Tobago expressed anger at having not been consulted. Any state that wanted to be exempt from daylight saving time could do so by passing a state law, provided that it exempt the entire state. Five other Caribbean nations participated with Dominica and the USA in the campaign, called Operation Urgent Fury. federal Uniform Time Act of 1966 mandated that daylight saving time begin nationwide on the last Sunday of April and end on the last Sunday of October. Six days later, the island was invaded by forces from the United States at the behest of Dame Eugenia Charles, of Dominica. The U.S. This led to Bishop's house arrest; he and many others were eventually executed at Fort George on October 19, 1983. This resulted in a patchwork where some areas observed DST while adjacent areas did not, and it was not unheard of to have to reset one's clock several times during a relatively short trip (e.g., bus drivers operating between Moundsville, West Virginia, and Steubenville, Ohio had to reset their watches seven times over 35 miles). A power struggle developed between Bishop and a Stalinist sect within the ruling People's Revolutionary Government (PRG), loyal to the more hardline communist ideologue and co-founder of the NJM, Bernard Coard. States and localities were free to observe daylight saving time or not. Bishop's failure to allow elections, coupled with his Marxist-Leninist socialism and cooperation with communist Cuba did not sit well with the country's neighbours, including Trinidad and Tobago, Barbados, Dominica and the United States. federal law did not address daylight saving time. Eric Gairy's government became increasingly authoritarian and dictatorial, prompting a coup d'état in March 1979 by the charismatic and popular left-wing leader of the New Jewel Movement, Maurice Bishop. From 1945 to 1966, U.S. Independence was granted in 1974 under the leadership of the then Premier Sir Eric Matthew Gairy, who became the first Prime Minister of Grenada. This remained in effect until World War II began winding down and the requirement was removed on September 30, 1945. In 1967 Grenada attained the position of "Associated State of the United Kingdom", which meant that Grenada was now responsible for her own internal affairs, and the UK was responsible for her defence and foreign affairs. Daylight saving time was reinstated in the United States on February 9, 1942, again as a wartime measure to conserve resources. The island was a province of the short-lived West Indies Federation from 1958 to 1962. Beginning in 2007, it will start DST on the second Sunday in March, and change back to standard time on the first Sunday in November. Grenada was made a Crown Colony in 1877. Through the end of 2006, the United States starts its DST on the first Sunday in April, and changes back to standard time on the last Sunday in October. The island was ceded to the United Kingdom in 1763 by the Treaty of Paris. state of Arizona, which also does not observe DST. Vincent who feared losing their trade routes to the mainland. The Mexican state of Sonora does not observe DST because it borders on the U.S. After a failed English settlement attempt, the French 'purchased' the island from the indigenous people in 1650, which resulted in warfare with the Caribs of Dominica and St. Mexico has adopted DST nationwide, even in its tropical regions, because of its increasing economic ties to the United States. At the time of settlement, the island was occupied either by Island Caribs (Kalinago) or by their mainland cousins, the Kariña. Since April 2004, Cuba has remained on DST. The recorded history of Grenada begins in 1498, when Christopher Columbus first sighted the island and named it Conception. Cuba always starts its DST on April 1 but the end date varies. Main article: History of Grenada. Saskatchewan Government Relations gives further details on Saskatchewan's time policies. . Lloydminster and its immediately surrounding region in Saskatchewan use the same timekeeping routine used by Alberta, DST with Mountain Standard Time. It is located north of Trinidad and Tobago, and south of Saint Vincent and the Grenadines. The charter of the city of Lloydminster, which is bisected by the Saskatchewan–Alberta border, gives it a special exception (among areas in Saskatchewan) to use DST. Grenada is the second-smallest independent country in the Western Hemisphere (after Saint Kitts and Nevis). Observationally, this is equivalent to the province being on Mountain Daylight Time year-round, though officially the province is considered to be part of the Central time zone. Grenada is an island nation in the southeastern Caribbean Sea including the southern Grenadines. (This policy was implemented when the Saskatchewan Time Act was passed in 1966, to solve the problems that arose when time zones varied from town to town.) Thus, in the summer months Saskatchewan is in sync with Mountain Daylight Time and in the winter months it is in sync with Central Standard Time. The province of Saskatchewan is the largest part of that country that does not use DST, that is, it does not adjust clocks in spring and fall. Stark, publisher; London, Sampson Low, Marston & Company. The remaining provinces and territories will continue change time on the first Sunday of April and last Sunday of October unless they change their legislation. Boston, James H. In 2007, their DST will start on the second Sunday of March, and return to standard time on the first Sunday in November. Vincent; also a trip up the Orinoco and a description of the great Venezuelan Pitch Lake. rules (The Calgary Sun). Stark's Guide-Book and History of Trinidad including Tobago, Grenada, and St. The governments of Ontario, Manitoba, Quebec, and Alberta have pledged to change their daylight saving rules to match the new U.S. 1897. In Canada, time is under provincial and territorial jurisdiction, not federal. Stark, James H. Also, in 1988, they experimented with Double Daylight Time, when the clocks went ahead by two hours, instead of the usual one hour. Saint Patrick. The Canadian province of Newfoundland and Labrador is an exception in that the time changes take place at 00:01 local standard time and 00:01 local daylight time respectively. Saint Mark. In 2007, the starting and ending dates for DST will change in the United States and parts of Canada (see below). Saint John. North America generally follows the same procedure, going by local time in each zone, each time zone switching at 02:00 LST (local standard time) to 03:00 LDT (local daylight time) on the first Sunday in April, and again from 02:00 LDT to 01:00 LST on the last Sunday in October. Saint George. Polar or near-polar locations such as Iceland often opt out, as summer in these locations usually brings nearly uninterrupted daylight. Saint David. With Iceland observing UTC all year round, despite being at a longitude which would indicate UTC-1, the country may be said to be on continuous DST. Saint Andrew. Thus in Moscow (local time = UTC+3 in winter, UTC+4 in summer), daylight-saving time commences at 23:00 UTC on the day before the last Sunday in March, and ends at 23:00 UTC on the day before the last Sunday in October. In Russia, however, although the changeover dates are the same, clocks are moved forward or back at 02:00 winter time in all zones. (See also: European Summer Time). from local times of 01:00/02:00/03:00 to 02:00/03:00/04:00 in March, and vice versa in October. In the West European (UTC), Central European (UTC+1), and East European (UTC+2) time zones the change is simultaneous: on both dates the clocks are changed everywhere at 01:00 UTC, i.e. All countries in Europe, except Iceland as noted below, observe daylight-saving time and change on the same date: moving clocks forward one hour on the last Sunday in March and back one hour on the last Sunday in October. The Department of Internal Affairs gives further historical information on their website. In New Zealand, daylight saving time begins at 2am (standard time) on the first Sunday in October each year, and ends at 2am (standard time) on the third Sunday of March. See the Australian time zones article or this site for maps and further information on standard and daylight saving time in Australia. Queensland experimented with it for a year or two in the early 1970s, but it was not popular and was abandoned. Western Australia, Northern Territory and Queensland do not have daylight saving. Tasmania starts DST earlier than the others, usually near the beginning of October. New South Wales, Victoria, Tasmania, Australian Capital Territory and South Australia apply daylight saving time. Some states/territories implement it and some do not. In Australia, daylight saving time is a state/territory-based initiative. It has not used DST since then. Pakistan experimented with DST in 2002 going from +5:00 to +6:00. For more on this subject, see Israeli Daylight Saving Law. Israel's Daylight Saving Time rules have changed repeatedly in recent years; there has been trouble reaching a consensus regarding Gregorian calendar end dates for DST as they are dependant on Jewish Holidays, which follow the lunar Hebrew calendar. Israel adopts Daylight Saving Time on the last Friday before April 2 at 02:00, and returns to standard time at 02:00 of the Sunday of the month of Tishrei between Rosh Hashanah and Yom Kippur. Thus, DST in Iran starts on the first day of Farvardin (around 21-22 March) and ends on the first day of Mehr (around 22 September). Iran uses the Persian calendar. India used DST briefly during its wars with Pakistan and China. The PRC now uses one universal time zone for all of the nation from Urumqi in the northwest to Fujian in the southeast; the size of the nation was a major factor why DST was not considered practical in China. The People's Republic of China experimented with DST from 1986, but abandoned it in the 1990s. Egypt operates Daylight-Saving Time between the last Friday in April and the last Thursday in September when the clocks are 3 hours ahead of Greenwich Mean Time (GMT+3). In the Southern Hemisphere, the beginning and ending dates are switched (thus the time difference between, e.g., the United Kingdom and Chile may be three, four, or five hours). DST commonly begins in the Northern Hemisphere on either the first Sunday in April or the last Sunday in March, and ends on the last Sunday in October. With a few exceptions, switchovers between standard time and daylight saving time generally occur in the early morning hours of a Sunday morning, presumably because doing so then causes less disruption than a change on a weekday would. The dates of the beginning and ending of DST also vary by country. The amount of the time shift varies, but one hour is the most common. state in the tropics, does not observe DST. Hawaii, the only U.S. Daylight saving time is generally a temperate zone practice; day lengths in the tropics do not vary enough to justify DST. The law, however, proved so unpopular (mostly because people rose and went to bed earlier than in current times) that the law was later repealed. It was observed for seven months in 1918 and 1919. Congress established several time zones (which were already in use by railroads and most cities since 1883) and made daylight saving time official (which went into effect on March 31) for the remainder of World War I. Then on March 19, 1918, the U.S. Shortly afterward, the United Kingdom followed suit, first adopting DST between May 21 and October 1, 1916. The idea of daylight saving time was first put into practice by the German government during the First World War between April 30 and October 1, 1916. It was first seriously proposed by William Willett in the "Waste of Daylight", published in 1907, but he was unable to get the British government to adopt it despite considerable lobbying. (Read the full text.) However, the article was humorous; Franklin was not proposing DST, but rather that people should get up and go to bed earlier. It is sometimes asserted that DST was first proposed by Benjamin Franklin in a letter to the editors of the Journal of Paris. . Note that the term commonly used in the United States, daylight savings time, is incorrect, for both historic (the correct name as provided by the act which inaugurated it in the United States is daylight saving time) and grammatical reasons. DST is most commonly used in temperate regions, due to the considerable variation in the amount of daylight versus darkness through the seasons in those regions. This is intended to provide a better match between the hours of daylight and the active hours of work and school. The official time is adjusted forward, (usually) one hour from its official standard time, remaining that way for the duration of the spring and summer months. Daylight saving time (also called DST) is a term used for a system intended to "save" daylight (It is also known as summer time in both Britain and Europe). American Journal of Public Health 85, 92–95. (1995) Daylight saving time and motor vehicle crashes: the reduction in pedestrian and vehicle occupant fatalities. et al. ^ Ferguson, S.A. Their observance of DST was unofficial in this case, as a strict reading of the Uniform Time Act would not allow for this situation, but by observing DST, they remained synchronized with the greater Louisville and Cincinnati metropolitan areas. 2 counties near Cincinnati, Ohio and 3 counties near Louisville, Kentucky were on Eastern Standard time but did observe DST. 5 northwestern counties near Chicago, Illinois and 5 southwestern counties near Evansville, Indiana were on Central Standard Time and did use DST. 77 counties — most of the state — were on Eastern Standard Time but did not use DST. |
