Baltimore, MD - Mar. 9 - You’ll want to think about going to bed early tonight because Daylight Saving Time starts at 2 a.m. Sunday, March 10. That means you’ll “spring ahead” and move your clocks forward one hour—and, unfortunately, lose that hour of sleep.

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.)

Many electronic devices, like your cell phone and computer, automatically adjust when Daylight Savings Time begins or ends.

So, why do we do this at 2 a.m., and why shift our clocks at all?
