U.S. daylight saving time |
U.S. daylight saving time In 1918, the U.S. first began daylight saving time (DST) on Easter Sunday, when clocks were set ahead by one hour. The idea was sponsored by the Daylight Savings Association. N.Y. Senator William M. Calder introduced the bill to Congress on 17 Apr 1917. It was initially defeated, but subsequently passed by roll-call on 27 Jun 1917. In recent years in the U.S., up to 2006, clocks were changed at 2 a.m. on the first Sunday in April, and reverted on the last Sunday of October. Effective in 2007, DST is set by Congress to begin on the second Sunday of March and end the first Sunday of November. The concept had already been introduced in Great Britain as a fuel-saving measure during wartime, in order to conserve coal stocks during WW I. |
