By now, most people in Bel Air have noticed that daylight is beginning a little earlier each morning.

That means spring and Daylight Saving Time are near. In 2013, the big shift happens on Sunday, March 10.

On that date, most of the U.S. will 'spring' 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.

And when does it end? DST will last until Nov. 3, 2013.

The change affects all states except Arizona and Hawaii.

The time change used to start four weeks later than it does now, but in 2005, President George W. Bush signed a bill that extended Daylight Saving Time to preserve energy, according to NASA's website on the topic.

Since 2007, Daylight Saving Time has started every year at 2 a.m. on the second Sunday in March, according to NASA.

Of course, many people would prefer that Daylight Saving Time become the norm and that time would not shift back to standard time in the fall.

A Florida legislator even introduced the "Sunshine Protection Act" in the state legislature to try to make that happen. He admits it has little chance of passing, but he wants to stimulate discussion on the topic.
