Washington A sure sign that spring is on the horizon: daylight saving time has arrived.
Most Americans pushed the clock forward by 60 minutes before heading to bed Saturday night, but daylight saving time officially started in the wee hours Sunday at 2 a.m. local time.
You may have lost an hour of sleep, but in the months ahead you'll gain an extra hour of sunlight in the evenings.
It's also a good time to put new batteries in warning devices such as smoke detectors.
The time change was not observed by Hawaii, most of Arizona, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Marianas.
Clocks fall back to standard time on Nov. 2.
