Daylight Saving Time: Set Clocks Ahead 1 Hour

Spring is closer than you think, and here's a sure sign: Daylight saving time arrives this weekend.

Most Americans will set their clocks 60 minutes forward before heading to bed Saturday night. Daylight saving time starts Sunday at 2 a.m. local time.

You may lose an hour of sleep, but daylight saving time promises an extra hour of evening light for many months ahead.

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.
