The idea of daylight saving was first conceived by Benjamin Franklin (portrait at right) during his sojourn as an American delegate in Paris in 1784, in an essay, "An Economical Project."
The idea was first advocated seriously by a London builder, William Willett (1857-1915), in the pamphlet "Waste of Daylight" (1907) that proposed advancing clocks 20 minutes on each of four Sundays in April, and retarding them by the same amount on four Sundays in September. 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. When questioned as to why he didn't simply get up an hour earlier, Willett replied with typical British humor, "What?" In his pamphlet "The Waste of Daylight" he wrote:
The Uniform Time Act
By 1966, some 100 million Americans were observing Daylight Saving Time based on their own local laws and customs. Congress decided to step in to end the confusion and establish one pattern across the country. The Uniform Time Act of 1966 (15 U.S. Code Section 260a) which was signed into Public Law 89-387 on 12 April 1966, by President Lyndon Johnson, created Daylight Saving Time to begin on the last Sunday of April and to 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.
The Uniform Time Act of 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.
In 1972, Congress revised the law to provide that, if a State was in two or more time zones, the State could exempt the part of the State that was in one time zone while providing that the part of the State in a different time zone would observe Daylight Saving Time. The Federal law was amended in 1986 to begin Daylight Saving Time on the first Sunday in April.
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 saves energy. Based on consumption figures for 1974 and 1975, The Department of Transportation says observing Daylight Saving Time in March and April saved the equivalent in energy of 10,000 barrels of oil each day -- a total of 600,000 barrels in each of those two years.
