Worldwide daylight saving

Today, approximately 70 countries utilize Daylight Saving Time in at least a portion of the country. Japan, India, and China are the only major industrialized countries that do not observe some form of daylight saving.

Not the tropics

Equatorial and tropical countries (lower latitudes) generally do not observe Daylight Saving Time. Since the daylight hours are similar during every season, there is no advantage to moving clocks forward during the summer. China has had a single time zone since May 1, 1980, observing summer Daylight Saving Time from 1986 through 1991; they do not observe DST now.

List of countries

Most countries that observe Daylight Saving Time are listed in the table below. They all save one hour in the summer and change their clocks some time between midnight and 3:00 a.m.

Note that there are many oddities. For example, some parts of the U.S. and Canada do not observe Daylight Saving Time, such as the state of Arizona (U.S.) and the province Saskatchewan (Canada). For the U.S. and its territories, Daylight Saving Time is NOT observed in Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands, and Arizona. The Navajo Nation participates in the Daylight Saving Time policy, even in Arizona, due to its immense size and location in three states.


Observance can also be erratic. For example, Chile delayed its changeover date for the Pope's visit in 1987, as well as for a presidential inauguration in 1990.

Clark Dam at Butlers Gorge in Tasmania. The bulk of the electricity in Tasmania is generated by hydroelectric stations, causing an energy shortage in the drought of 1967.

Australia
In Australia, daylight saving was first introduced during World War I under Commonwealth legislation which, due to wartime emergency, was binding on all the states. During the World Wars, Daylight Saving Time was implemented for the late summers beginning January 1917 and 1942, and the full summers beginning September 1942 and 1943. (Western Australia did not use DST during the summer of 1943.)

In 1967, Tasmania experienced a drought, which depleted their reserves of water. The state government introduced one hour of daylight saving that summer as a means of saving power and hence water. Tasmanians reacted favorably to daylight saving and the Tasmanian government has declared daylight saving each summer since 1968. After persuasion by the Tasmanian Government, all states (except Western Australia and the Northern Territory) passed legislation in 1971 for a trial season of daylight saving. The following year, New South Wales, South Australia, and Victoria joined Tasmania for regular daylight saving, but Queensland did not do so until 1989.

Tasmania, Queensland, and Western Australia have had erratic schedules, often changing their dates due to politics and to accommodate festivals. In 1992, for example, Tasmania extended daylight saving by an additional month while South Australia began extending daylight saving by two weeks to encompass the Adelaide Festival. In some years, Victoria extended daylight saving to the end of March for the Moomba Festival and South Australia and New South Wales followed suit for consistency. Special daylight saving arrangements were observed during the Sydney 2000 Olympic Games. Queensland does not have daylight saving, although they implemented it from 1989 to 1982 before it was voted down. Although DST was well received in South East Queensland, it was a major inconvenience to the rest of the state. As resident Samantha Rannard commented, "You do not need an extra hour of daylight when it is 98% humidity and 35 degrees Celsius in the tropics!" On the Gold Coast, which borders New South Wales, some businesses do adopt it, but many do not.

In response to the problems caused by the lack of uniformity, a Private Members Bill, the National Measurement (Standard Time) Amendment Bill 1991, was introduced into Federal Parliament in May 1991 by Ron Edwards, Member for Stirling in WA, to define a national system of time zones and Daylight Saving Time for Australia and its external territories. But in March 1992, the Federal Government decided not proceed with the bill, and the setting of time zones and daylight saving remains the responsibility of the state and territory governments. The lack of uniformity of daylight saving in Australia continues to cause significant problems for the transportation and communication industries. It also reduces the number of hours in the working day that are common to all centers in the country. In particular, time differences along the East Coast cause major difficulties, especially for the broadcasters of national radio and television.

Western Australia enacted a three-year trial of Daylight Saving Time beginning in December 2006.

Asia

Japan
In Japan, Daylight saving was introduced after World War II by the U.S. occupation but was dispensed with in 1952, following opposition from farmers. Despite efforts by the Ministry of International Trade and Industry to have daylight saving introduced to cut Japan's energy consumption, opposition from farmers and the Ministry of Education (which was concerned that lighter evenings would entice school children from their homework) has continued to win the day
Israel

Israel always has Daylight Saving Time, but until 2005, it was decided every year by the Ministry of Interior. There was no set rule for Daylight Saving/Standard time changes, and there was long-running debate between the majority of the secular public who wanted to extend daylight saving as long as possible, and the religious public who wanted to end it before Yom Kippur. One element was entrenched in law, however: that there had to be at least 150 days of Daylight Saving Time annually. From 1993 to 1998, the change to Daylight Saving Time was on a Friday morning from midnight IST to 1:00 a.m. IDT; up until 1998, the change back to Standard Time was on a Saturday night from midnight Daylight Saving Time to 11:00 p.m. Standard Time. An exception was 1996, when the change back to Standard Time took place on Sunday night instead of Saturday night to avoid conflicts with the Jewish New Year. From 1999 to 2004, the change to Daylight Saving Time was on a Friday morning, but from 2:00 a.m. IST to 3:00 a.m. IDT; and the change back to Standard Time was on a Friday morning from 2:00 a.m. IDT to 1:00 a.m. IST.

The disputed territories have had varying Daylight Saving Time rules as the dramatic politics of the region have swayed the occupying power. Being closer to the equator than Europe, there is less need for DST, but it has generally been observed anyway. At present, as a sign of independence from Israeli rule, the Palestinian National Authority uses a different schedule for Daylight Saving Time than Israel.

Early in the twentieth century, the British were quick to standardize time, and from 1917 until May 15, 1948, all of Palestine, including the parts now known as the Gaza Strip and the West Bank, was under British rule and followed British time changes.

From May 15, 1948 to June 5, 1967, the Gaza Strip was mostly under Egyptian rule and followed Egyptian policy. The rest of the area was under Jordanian rule at that time, formally annexed in 1950 as the West Bank. So the rules for Jordan for that time apply. Major towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and East Jerusalem. Both areas followed Israeli time when they were occupied by Israel in June 1967, but not annexed (except for East Jerusalem). The Palestinian National Authority was established in 1993, and controlled most towns in the West Bank and Gaza by 1995, at which time the Palestinians began using their own time change dates, separate from Israel's.

Kyrgyzstan
Kyrgyzstan began keeping Daylight Saving Time year round in 2005.

Pakistan
Pakistan implemented Daylight Saving Time in 2002, but then discontinued it.

Philippines
The Philippines introduced short periods of Daylight Saving Time between 1986 and 1998 to conserve energy, and in April 2006 the Department of Trade and Industry proposed that Daylight Saving Time again be implemented to combat rising oil prices.

South Korea
Although South Korea does not currently observe Daylight Saving Time, the country did adhere to DST from 1948 to 1951, 1955 to 1960, and 1987 to 1988.

Taiwan
Taiwan has had an on-again, off-again relationship with Daylight Saving Time, having observed it from 1945 to 1961 and 1974 to 1975.

Europe

European Union
While European nations have been taking advantage of the time change for decades, in 1996 the European Union (EU) standardized an EU-wide "summertime period." The EU version of Daylight Saving Time runs from the last Sunday in March through the last Sunday in October. Iceland observes the Western European time zone year round, and does not change its clocks for Daylight Saving Time.

Russia
During the summer, Russia's clocks are two hours ahead of standard time. For example, Moscow standard time (UTC+3) is about a half-hour ahead of local mean time (UTC+2:30); this is about the same situation as Detroit, where the standard time (UTC-5) is also about a half-hour ahead of local mean time (UTC-5:32). During the winter, all 11 of the Russian time zones remain an hour ahead of standard time. With their high latitude, the two hours of Daylight Saving Time significantly extend daylight during waking hours.

North America

Cuba
Cuba has observed Daylight Saving Time since 2004.

Honduras
Honduras observed Daylight Saving Time during 1994, and again in 2006, though for only three months. Honduras will also observe DST from 2007-2009.

Mexico
Mexico, with the exception of Sonora, has observed Daylight Saving Time since 1996, adhering to the same schedule as the U.S. Although the U.S. is slated to change Daylight Saving Time dates in 2007, Mexico will maintain the original schedule of starting the first Sunday in April and ending the last Sunday in October.

Nicaragua
Nicaragua implemented Daylight Saving Time as an energy-saving measure from 1992 to 1994, then again beginning in 2004.

Antarctica
The Antarctic Peninsula (Palmer Station) uses Chile's time zone, but the rest of the continent does not. Rothera, a British base, does not implement daylight saving, but instead remains GMT -3. U.S. bases, including both McMurdo and Amundsen-Scott South Pole Station, use New Zealand's time zone and daylight saving dates.

It has less to do with how far east they are than with how far north or south they are.

During polar summers, days are extremely long. On the longest day of the year, the sun just hits the horizon and begins to rise again. In polar winters, the opposite is true. On the shortest day of the year, the sun appears as a glow just below the horizon.

As you move away from the poles towards the equator, the difference between day and night is less pronounced as the seasons change, so there really isn't as much need to make a seasonal adjustment.

It's a good point - looking into my crystal ball, the start time won't change, bad light will end play early 5 out of 5 days (assuming we get in 5 days), the shadows on the field will be rediculously long, and Brian and the rest of the commentry team will be moaning about this very issue - with the usual, tv audience size, money rules etc, etc being put forward as the excuses as to why not. As usual we will be none the wiser and everyone wins except the fans! Right on NZ cricket way to promote the game! And btw, what's with the coverage being on Skysport Channel 3 for crying out loud?! I shake my head.....our talent pool is small enough without making the game inaccessable to our future cricketers.

I live in Arizona USA, and it is one of the only 2 states that do not do Daylight Savings Time. My boss said that they do not do it in India and my friends in Japan said it doesn't affect them either, so maybe all of Asia doesn't do it. Beyond that, I'm not much help in this area. DST confuses me.

2007-04-12 06:31:33 · answer #4 · answered by shadedtint 4 · 0 0

we do it in america for the farmers.
we move it back an hour when its winter, so when the farmers wake up it isnt as dark.
and forward in the summer, so it stays light longer.
its very pointless though. seeing as how farmers work from sun up to sun down dispite what time it is.

also people say it has to do with it being safer to drive in the morning when it is lighter.


as for why other countrys dont do it, they dont feel the need to.

i personally think its quite pointless.

hope that helped.

To save energy. One hour earlier means more use of day light in the summer. The day light is longer in the summer. In winter every thing goes back to normal.

Just to confused people lol kidding. Its interesting to know though that America has daylight savings time. I thought it only happens in Australia. One lesson I learnt today:)

It's not something they observe. It's like some places in North America don't observe it cause farmers don't like it .
