WASHINGTON (AP) — It’s time to reclaim that hour of sleep you lost last spring.

Most of the United States is turning back the clock this weekend for the annual shift back to standard time.

For many, that means making the switch before hitting the sack Saturday night, even though the change doesn’t become official until 2 a.m. Sunday local time.

Residents of Hawaii, most of Arizona and some U.S. territories don’t have to change; daylight saving time is not observed in those places.

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 — March 8, 2015.
