Get ready to lose an hour of sleep this weekend. Daylight Savings Time 2013 begins on Sunday, March 10, forcing people in most states in the U.S. to turn their clocks ahead.
What time does Daylight Savings Time start? The time change begins at 2:00 a.m. on Sunday, so it's time to spring forward and set your clock an hour ahead before you go to bed on Saturday night.
Most U.S. states and territories participate in DST, but if you live in Hawaii, Arizona (with a few exceptions), the U.S. Virgin Islands, Puerto Rico, and American Samoa, you do not need to change the time on your clock on Sunday.
Once the time changes, it won't get dark as early. That's a fair trade for losing an hour of sleep this weekend.
Although you probably aren't thrilled about losing a little sleep, at least spring is right around the corner.
This year, spring begins on March 20, with many people looking forward a change in season after a snowy winter in many areas of the country.
When does Daylight Savings Time end? Turn your clocks back on Sunday, Nov. 3, 2013.
