WASHINGTON (March 2, 2007) — The U.S. Department of Transportation issued a reminder today that daylight-saving time will begin at 2 a.m. on Sunday, March 11, three weeks earlier than in recent years.
Prior to this year, daylight-saving time has been observed from the first Sunday in April to the last Sunday in October. As a result of legislation enacted by Congress in 2005, beginning this year daylight-saving time will begin the second Sunday of March and end the first Sunday of November. As a result, this year daylight-saving time will run from March 11 to Nov. 4.
When daylight-saving time begins, clocks will be set ahead one hour, providing an additional hour of daylight in the evening.
Federal law does not require any area to observe daylight saving time. But if a state chooses to observe daylight-saving time, it must follow the starting and ending dates set by the law. In those parts of the country that do not observe daylight time, no resetting of clocks is required. Those states and territories include Arizona, Hawaii, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Marianas.
