the real use of the day light savings times started from World War I. (or II) they used it to save the fuel during the war for lights. here are some real facts.
<< William Willett (1865-1915). As he was taking an early morning a ride through Petts Wood, near Croydon, Willett was struck by the fact that the blinds of nearby houses were closed, even though the Sun was fully risen.
In his pamphlet "The Waste of Daylight" he wrote:
"Everyone appreciates the long, light evenings. Everyone laments their shortage as Autumn approaches; and everyone has given utterance to regret that the clear, bright light of an early morning during Spring and Summer months is so seldom seen or used".
His campaign led to the introduction of British Summer Time in an Act of Parliament in 1916. Clocks were put one hour ahead of GMT during the Summer months. The energy saving benefits of this were recognised during World War II, when clocks were put two hours ahead of GMT during the Summer. This became known as Double Summer Time. During the war, clocks remained one hour ahead of GMT throughout the winter.
It was during the Big War (World War I) that daylight saving time was adopted by several countries. The reason was that the clocks were moved forward by an hour, thus saving fuel that would be necessary to produce light in the late hours of the day. It was during another war, World War II, that United States kept time one hour ahead of the default standard time (from February 9th, 1942 to September 30th, 1945). During that period no changes to the time were done during the summer months.
The Uniform Time Act, enacted by the U.S. Congress in 1966, established a system of uniform (within each time zone) daylight saving time throughout the U.S. and its possessions, exempting only those states in which the legislatures voted to keep the entire state on standard time.
Under legislation enacted in 1986, daylight saving time in the USA
begins at 2 a.m. on the first Sunday of April and
ends at 2 a.m. on the last Sunday of October
In most of the countries of western Europe, including the countries that are members of the EEC, daylight saving time:
begins at 1 a.m. GMT on the last Sunday of March and
ends at 1 a.m. GMT on the last Sunday of October
Daylight Saving Time - for the U.S. and its territories - is not observed in Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands, the Eastern Time Zone portion of the State of Indiana, and by most of Arizona (with the exception of the Navajo Indian Reservation in Arizona).
