WASHINGTON — A sure sign that spring is on the horizon: It’s time to set the clocks forward for daylight saving time.

Most Americans will set their clocks 60 minutes later before heading to bed Saturday night, but daylight saving time officially starts Sunday at 2 a.m. local time.

You lose an hour of sleep, but daylight saving time arrives with the promise of many months ahead with an extra hour of evening light.

It’s also a good time to put new batteries in warning devices such as smoke detectors and hazard warning radios.

The time change is not observed by Hawaii, most of Arizona, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Marianas.

Daylight saving time ends Nov. 2.
