Daylight Saving Time 2013: Set Clocks Forward On Sunday, March 10    

 Spring must be around the corner. It's time to set the clocks forward for daylight saving time.

At 2 a.m. local time Sunday, daylight saving time arrives with the promise of many months ahead with an extra hour of evening light.
You lose an hour of sleep, but make sure to turn the clock ahead – spring forward – before heading to bed Saturday night to avoid the panic of a late rise.
It's also a good time to put new batteries in warning devices such as smoke detectors and hazard warning radios.

Some places don't observe daylight saving time. Those include Hawaii, most of Arizona, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Marianas.
