In 2013, Daylight Saving Time (United States) begins at 2:00 a.m. on Sunday, March 10. That means you’ll spring ahead and move your clocks forward one hour.
The benefit is that we’ll get more sunlight later in the evening and it’s a pleasant sign that spring is just around the corner. Spring 2013 officially starts on Wednesday, March 20.
When you change your clocks in the fall and spring because of Daylight Saving Time, it’s also a good time to change batteries in your smoke and carbon monoxide detectors, and check to make sure the devices are in working order.
