It’s that time again: Don’t forget to set your clocks back an hour; think fall back

WASHINGTON—Most people in the United States are getting an extra hour of sleep this weekend, thanks to the annual shift back to standard time.

Officially, the change comes at 2 a.

m. Sunday, but most people set their clocks back before heading to bed Saturday night.

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

Public safety officials say this is 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.
