By now, most people have noticed that daylight is beginning a little earlier each morning.
That means that spring — and Daylight Saving Time — is near. In 2013, the big shift happens on Sunday, March 10.
On that date, most of the United States will set clocks forward at 2 a.m., meaning, yes, that you'll lose an hour of sleep. But you'll get an extra hour of daylight at the end of the day.
The time change will last until November 3, 2013, when clocks will fall back an hour.
The change affects all of the U.S., except states Arizona and Hawaii; and territories: American Samoa, Guam, Puerto Rico, and the Virgin Islands.
