Most Americans will set their clocks 60 minutes forward before heading to bed Saturday night, but daylight saving time officially starts Sunday at 2 a.m. local time (0700GMT).
An hour of sleep is lost, but daylight saving time arrives with the promise of many months ahead with an extra hour of evening light, reports AP.
The time change is not observed by Hawaii, most of Arizona, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Marianas.
It also means the United States is four hours behind Greenwich Mean Time instead of five.
Daylight saving time ends Nov. 2.
