Africa

No country in Africa observes daylight saving time except those listed below:

Egypt

Egypt normally observes DST between the last Thursday in April and the last Thursday in September when the clocks are three hours ahead of Greenwich Mean Time (UTC+3). The change is at midnight (local time); i.e. one second after 23:59:59 on that Thursday becomes 23:00:00 Thursday. The date does not change when the first 00:00 midnight occurs, for all practical purposes, midnight does not occur until then. However, the 2006 rule is an exception: the clock falls back September 22 at 01:00 so as not to disrupt Ramadan, and possibly similar exceptions will apply in 2007 and 2008.

Namibia

DST begins on the first Sunday in September, and ends on the first Sunday in April.

Tunisia

Tunisia adopted Daylight saving time for the first time in 2005 starting 1st May 2005 and following EU time schedules thereafter. This comes as a move by the government to try and promote saving of energy in the wake of the ever-rising cost of fuel in the world market.

Asia

China

The People's Republic of China experimented with DST from 1986, but abandoned it in the 1990s. The PRC now uses one time zone for the whole country; the size of the nation was a major factor why DST was not considered practical in China.

India

India used DST briefly during war times.

Iran

Before 1979, DST was observed in Iran. Thereafter it was abandoned until 1989, when it started on the first day of Farvardin (21-22 March) in the Iranian calendar and ended on the first day of Mehr (23-24 September). In 2006, Iran stopped observing DST.[1]

Israel

Israel observes DST starting on the last Friday before April 2 and ending at 2 AM on the Sunday between Rosh Hashanah and Yom Kippur. Until 2005, the schedule was variable: the only requirement was that there be at least 150 days per year of DST, and was set out each year by the Ministry of the Interior.[2]

In territories controlled by the Palestinian National Authority, DST ends later, which can lead to some confusion. On September 5, 1999, terrorists were transporting a bomb that they mistakenly thought was set to go off at 5:30 PM Israel Standard Time; it was actually set for 5:30 PM Palestinian Daylight Time, which was an hour ahead. As a result, the bomb went off while the bomb was still being transported, killing the terrorists (and earning them a Darwin Award).[3]

Japan

From 1948 to 1951, Japan observed DST between May and September every year under an initiative of the U.S.-led occupation army. The unpopularity of DST, for which people complained about sleep disruption and longer daytime labor (some workers had to work from early morning till dusk), caused Japan to abandon DST around the same time that its independence was restored. Since then, DST has never been officially implemented nationwide in Japan.

Starting in the late 1990s, a movement to re-install DST in Japan gained some popularity, aiming at saving energy and increasing recreational time. The Hokkaido region is particularly in favor of this movement because daylight starts as early as 3:30 am (in standard time) there in summer due to its high latitude and its location near the eastern edge of the time zone. In the early 2000s, a few local governments and commerce departments promoted unmandated hour-earlier work schedule experiments during summer time without officially resetting clocks.

Jordan

Jordan UTC+2 observes daylight saving time from the end of March to the end of October.[citation needed]

Kazakhstan

Kazakhstan made a decision to stop observing DST in 2005.

Kyrgyzstan

Kyrgyzstan voted to stop observing DST in 2005 by remaining on UTC+6 as Standard Time (which used to be Kyrgyzstan Summer Time) to still save energy.

Pakistan

Pakistan experimented with DST in 2002, going from +5:00 to +6:00 on the first Sunday in April at 00:01 to the first Sunday in October at 00:01. It has not used it since then.

Philippines

The Philippines experimented with DST for shorter periods during the presidencies of Corazon Aquino (1986 to 1992) and Fidel Ramos (1992 to 1998). DST was primarily intended to help deal with the country's energy crisis by minimizing the number of hours where electric lighting was to be used. On April 2006, the Philippine Department of Trade and Industry again proposed that DST be implemented to help deal with rising oil prices.[4][5]

South Korea

South Korea observed DST from 1948 to 1951, from 1955 to 1960, and from 1987 to 1988. South Korea does not currently observe DST.

Syria

Syria observes DST at UTC+3, in 2006 from 30 March until 21 September (a change from 30 September).

Taiwan

Taiwan implemented DST from 1945 to 1961, revoked DST from 1962 to 1973, reinstated DST from 1974 to 1975, and revoked DST from 1976 onwards.

Asia


Oceania

Australia and New Zealand are the only countries in Oceania that observe daylight saving time, but Queensland, the Northern Territory and all external island territories (Niue, Christmas Island, etc.) don't observe daylight saving.

Australia

Main article: Time in Australia

In Australia, the decision to implement daylight saving time is left up to each state or territory. Some states or territories implement it and some do not.

New South Wales, Victoria, Tasmania, Australian Capital Territory and South Australia apply DST on a yearly basis. Tasmania commence daylight saving on the first Sunday in October, while other states begin on the last Sunday in October.

In 2006, the Western Australia Parliament approved a three year daylight saving trial, which will run from the summer of 2006-2007 until the summer of 2008-2009, after which a referendum will be held to determine if it should be put in place permanently. The move towards a trial was backed with large amounts of media coverage.

The Northern Territory and Queensland do not officially have DST. Queensland experimented with DST for a year or two in the early 1970s, and again in the early 1990s, but it was abandoned after a majority of residents voted against its introduction in a 1992 referendum.

New Zealand

Main article: Time in New Zealand

DST begins at 2 a.m. NZST on the first Sunday in October each year, and ends at 3 a.m. NZDT (or 2 a.m. NZST as defined in the Time Act 1974) on the third Sunday in March.

New Zealand time, including DST, is used by several Antarctic bases that are supplied from New Zealand. This results in the oddity that the Amundsen-Scott South Pole Station sets its clocks an hour further ahead during the southern summer, when the sun is constantly above the horizon, than in the southern winter, when the sun is constantly below the horizon. The extreme geographic position of the base means that there is no possible adjustment of the daily activity cycle that can have any effect on the amount of sunlight received during those activities.

Europe

All countries in Europe except Iceland observe DST and change on the same date and time, starting on the last Sunday in March and ending on the last Sunday in October. Before 1996, DST ended on the last Sunday of September. In the West European (UTC), Central European (CET, 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.[6] See also: European Summer Time and British Summer Time which includes description of Double Summer Time.

Russia and the former USSR

In the USSR daylight saving time (Moscow Summer Time) was introduced on April 1 1981 by a decision of the Council of Ministers of the USSR. In Russia it was not abandoned after the breakup of the USSR. The changeover dates in Russia are the same as for other European countries, but clocks are moved forward or back at 02:00 standard time in all zones. Thus in Moscow (local time = UTC+3 in winter, UTC+4 in summer), DST 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 (note that "day before last Sunday" is not the same as "last Saturday" in a month where the last day is a Saturday).

Iceland

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. Polar or near-polar locations such as Iceland often opt out, as summer in these locations usually brings nearly uninterrupted daylight.

North America

North America generally follows the same procedure, with each time zone switching at 2:00 a.m. LST (local standard time) to 3:00 LDT (local daylight time) on the first Sunday in April, and again from 2:00 a.m. LDT to 1:00 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.[citation needed] Also, in 1988, they experimented with Double Daylight Time, when the clocks went ahead by two hours, instead of the usual one hour.

Canada

Main article: Time in Canada

In Canada, time is under provincial and territorial jurisdiction, not federal. The governments of Ontario, Manitoba, Quebec, Prince Edward Island, New Brunswick, Alberta, the Northwest Territories, British Columbia, Nova Scotia and Yukon Territory have so far pledged to change their DST rules to match the new U.S. rules. In 2007, their DST will start on the second Sunday in March, and return to standard time on the first Sunday in November. Newfoundland and Nunavut will continue to change time on the first Sunday in April and last Sunday in October unless they change their legislation. As noted below, Saskatchewan does not recognize DST.

Saskatchewan

The province of Saskatchewan is the largest part of the country that does not observe DST. Saskatchewan is bisected by the 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.) Saskatchewan is always on Central Standard Time. In the summer months, this matches adjacent areas that are on Mountain Daylight Time to the west and south, and in the winter months, it matches areas that are on Central Standard Time to the east. 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 boundary, 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.[7] Local custom in Denare Beach and Creighton, SK, is to observe DST, thereby keeping the same time as nearby Manitoba communities.

Quebec

The eastern reaches of Quebec's North Shore, east of 63° West longitude, are in the Atlantic Time Zone, but do not observe DST (see exception, below). The effect is that in summer, their clocks match those of the rest of the province, which observes Eastern Daylight Time. In October, their clocks are rejoined by their Atlantic Standard Time neighbors. Although places east of 63° West are officially on Atlantic Time, local custom is to use Eastern Time as far east as the Natashquan River. Those communities observe DST, including all of Anticosti Island, which is bisected by the 63rd meridian.

British Columbia

Most of British Columbia observes DST, but there is a large tract in east-central BC in the Mountain Time Zone that does not (most of BC is on Pacific Time). This includes Fort St. John, Charlie Lake, Taylor and Dawson Creek. The Crowsnest corridor between Creston and Yahk in the East Kootenays (southeastern BC) also keeps standard time year-round.

Nunavut

While the rest of Nunavut observes DST, Southampton Island including Coral Harbour remain on Eastern Standard Time throughout the year.

Ontario

Secluded in the heart of northwestern Ontario, Pickle Lake and New Osnaburgh have no use for DST. To the south, Atikokan also ignores it, using Eastern Standard Time year-round, effectively adopting Central Daylight Time in summer. Southern Ontario including Toronto, however, does observe DST. The power utilities of Ontario also do not use DST.

Cuba

Cuba remained on DST from April of 2004 until October 29, 2006. Cuba will restart DST again on March 2007.

Greenland

Greenland (excluding two minor areas at Danmarkshavn and Pituffik) observes DST and uses the European convention (DST begins 01:00 UTC last Sunday in March and ends 01:00 UTC last Sunday in October). Most of the country is in the UTC-3 zone in the winter (UTC-2 in the summer).

Guatemala

Guatemala started to use DST on April 30th 2006, ending on October 1st 2006. The implementation of DST has saved more than eight million dollars.[citation needed]

Honduras

Honduras adopted DST once from May 1994 until September 1994 but abandoned it that same year. On May 7th, 2006 it again used DST, however it ended on August 7th, 2006 making this the shortest use of DST in the northern hemisphere as it was only applied for 3 months. The government announced that the measure will be observed during the next three years 2007, 2008, 2009

Mexico

Mexico adopted DST nationwide in 1996, even in its tropical regions, because of its increasing economic ties to the United States. The Mexican state of Sonora has not observed DST since 1998 because its neighbor Arizona does not observe DST, and the important economic ties between these two states.[1] Although the United States has changed the schedule for DST beginning in 2007, Mexico will not be going along with it. DST has often been a contentious issue in Mexico and is not likely to be expanded.[2]

Nicaragua

Nicaragua observed DST since January 1 1992 until February 20 1994 but was stopped. On April 10 2005 until October 2 2005 was implemented DST, this year the period has been similar began on April 30 2006 and will be ending on October 1 2006, this measure is for energy conservation

In 2006

The schedule for 2006 in the United States was that DST began on the first Sunday in April (April 2, 2006), and changed back to standard time on the last Sunday in October (October 29, 2006). The time is adjusted at 2 AM local time.

From 2007

Beginning in 2007, DST will start on the second Sunday in March (March 11, 2007), and change back to standard time on the first Sunday in November (November 4, 2007). Under Section 110 of the Energy Policy Act of 2005, the U.S. Department of Energy is required to study the impact of the DST extension no later than nine months after the change takes effect. Congress has retained the right to revert to the DST schedule set in 1986 if it cannot be shown that there are significant energy savings from an extension of DST or if the extension may prove to be unpopular with the American public. One potential issue is that some northern regions on the western edge of time zones will, for the first time since the 1974-75 "almost year round" DST experiment, have sunrise times that occur after 8am.

Daylight saving for Halloween

One bill that has been pushed for the past several years, especially by Wyoming Senator Michael Enzi, is the Halloween Safety Act to extend DST by one week to end on the first Sunday of November instead of the last Sunday in October. The idea was to allow children to go trick-or-treating in more daylight. This extension passed with the Energy Policy Act of 2005.

Time Zone Standard Time Daylight Saving
USA Eastern -5 hours -4 hours (23:37)
USA Central -6 hours -5 hours (22:37)
USA Mountain -7 hours -6 hours (21:37)
USA Arizona -7 hours (20:37)
USA Pacific -8 hours -7 hours (20:37)

USA Aleutian -10 hours (17:37)
USA Hawaii -10 hours (17:37)
Current local times in 24-hour format are in parentheses.
Alaska

Alaska currently observes DST, but there is a statewide move to abolish it. As of July 24, 2006, Alaska's lieutenant governor Loren Leman approved a petition to collect signatures to put the initiative measure on the ballot by 2008. Due to Alaska's high latitude, Alaska has nearly round-the-clock daylight during summer and DST is seen by some Alaskans as unnecessary and a nuisance. Another issue is that the Alaskan mainland's single time zone is too wide and there is a large disparity between civil time and solar time with solar noon occurring as late as 3:00 P.M. by the clock in a place like Nome, Alaska. Others argue that ending daylight saving time will place Alaska as much as five hours from Eastern Standard Time, making coordination of travel and phone conversations more difficult.

Arizona

Arizona did observe DST in 1967 under the Uniform Time Act when the state legislature did not enact an exemption statute that year. In March 1968, the DST exemption statute was enacted and the state of Arizona has not observed DST since 1967 (however, the large Navajo Indian Reservation, which extends from Arizona into two adjacent states, does). This is in large part due to energy conservation since the temperature in and around Phoenix and Tucson is hotter than any other large U.S. metropolitan area during the summer, resulting in more power usage from air conditioning units and evaporative coolers in homes and businesses. An extra hour of sunlight while people are active would cause people to run their cooling systems longer, thereby using more energy.

Colorado

At the end of the 20th century, Colorado Springs Gazette columnist Ralph Routon wrote a series of columns supporting the idea of placing all of Colorado on year-round DST in order to save state residents the "aggravation of resetting their clocks every six months."[8] The idea gathered noticeable popular support within Colorado Springs, and attention of the state's larger newspapers,[9] but when then state Senator MaryAnne Tebedo attempted to present the idea to the state legislature, her research uncovered Federal laws forbidding the state-initiated extension of daylight saving time. Still determined to relieve Coloradans of the need to change their clocks, Tebedo introduced the only bill legally permitted to her: a proposal to exempt the state of Colorado from DST. The bill failed to escape committee during the 2000 legislative session.[10]

Hawaii

Because of Hawaii's tropical latitude, there is not a large variation in daylight length between winter and summer. Due to the location of Hawaiian archipelago, advancing the clock in Hawaii would have made sunrise times close to 7:00 A.M. even in June.[3] (Most of inhabited islands are located close to the west end of the Hawaii-Aleutian time zone, but Oahu, Kauai and Niihau are located more than 7 1/2 degrees west of the Hawaii-Aleutian time zone's meridian and should be ideally located in the next time zone to the west. Hawaii did experiment with DST for three weeks between April 30, 1933 and May 21, 1933; there is no record as to why it was implemented or ultimately discontinued.[11] Hawaii has never observed daylight saving time under the Uniform Time Act, having opted out of the Act's provisions in 1967.[12]

Indiana

See also Time in Indiana

Since 1970, most of Indiana in the Eastern Time Zone did not observe Daylight Saving Time, but the entire state started to do so in April 2006 after eight counties in western Indiana were shifted from the Eastern Time Zone to the Central Time Zone.[13]. One of the goals for observing DST was to get more Indiana counties observing the same timezone; formerly, 77 counties observed EST, 2 observed EST/EDT, and 13 observed CST/CDT. However, now Indiana has 18 counties observing Central Daylight Time while the remaining 74 counties observe Eastern Daylight Time.

Nevada

In 2005, Nevada Assembly Bill 18 would have exempted Nevada from Daylight Saving Time. The bill's author, Assemblyman Bob McCleary, D-North Las Vegas, argued that because of southern Nevada's desert climate, it would reduce power usage during the peak summer months by reducing the time that people would operate their home air conditioners. The result of not observing DST, however, would place the state in an odd time configuration relative to neighboring states. Because it is on the eastern edge of the Pacific Time Zone, Nevada (PST) would be two hours behind Utah (MDT), its eastern neighbor, and one hour behind California (PDT), its western neighbor. In the summer, it would therefore be the same time in Nevada (PST) as it would be in the majority of Alaska (AKDT). The bill died without a vote.[14]

United States of America Territories

The following United States of America territories do not follow DST: American Samoa, Guam, Puerto Rico, the U.S. Virgin Islands

North America and the Caribbean

South America

Brazil

Brazil adopted DST (called o horário de verão – "the hour of summer" – in Portuguese) for the first time in 1931, and has used it continuously since 1985 in the southern states (south, southeast regions and the states of Goiás and Mato Grosso do Sul), and in Bahia until 2004. Starting and ending dates are variable: normally, DST starts at midnight on an October (rarely November) Sunday and ends at midnight on a February or March Sunday. In 2006, DST will start on November 5 2006 and it will end on February 25 2007 in the states of Rio Grande do Sul, Santa Catarina, Paraná, São Paulo, Rio de Janeiro, Espirito Santo, Minas Gerais, Goiás, Mato Grosso, Mato Grosso do Sul and Distrito Federal.

Chile

Chile switches to DST at midnight at the end of the second Saturday in October and reverts to Local Standard Time (LST) at midnight at the end of the second Saturday 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 time zones. In specific years the starting and ending dates have been modified for political or climatic reasons. This year Chile will start DST on October 15th and it will be ending on March 11th 2007.

Colombia

From February 1992 until March 1993, Colombia suffered rolling blackouts of up to 10 hours a day due to a particularly strong El Niño season, which dried the reservoirs in hydroelectric plants in a country deriving 70% of its energy output from hydroelectric sources; consequently, the government decided to use DST to help save electricity. The experience did not have good results due to the low latitude; therefore it is no longer observed, although it was intended to be a temporary measure.[citation needed]

Paraguay

Paraguay observes DST. DST started on October 15 2006 and will end on March 11 2007.

Peru

Peru experimented with DST for one year during the 1990s; it is no longer observed.

Uruguay

Since 2004, Uruguay has observed DST. Starting in 2006, DST will start on the first Sunday in October and end on the second Sunday in March of every year.

South America
