Remember to set your clocks back an hour for the annual shift back to standard time.
Officially, the change occurs at 2 a.m. Sunday, but most people will set their clocks back before hitting the sack Saturday night.
Remember, it's fall back an hour.
Residents of Hawaii, most of Arizona and some U.S. territories don't have to change since they do not observe daylight-saving time.
Public safety officials say this is also a good time to put a new battery in the smoke alarm, no matter where you live.
Daylight saving time returns at 2 a.m. local time the second Sunday in March.
