Prepare yourself to lose an hour of sleep this weekend.

Clocks will spring forward an hour Sunday for Daylight Saving Time. Each year Daylight Saving Time runs from the second Sunday in March to the first Sunday in November. On Saturday the sun will rise in Washington at 6:47 a.m. and set at 6:06 p.m., but on Sunday there will be light later in the day with sunrise at 7:34 a.m. and set at 7:15 p.m.
