Time-saver.

This year, daylight saving time will start three weeks earlier and end one week later than usual.

During daylight saving time, people in most states will "spring" clocks forward by an hour. This causes the sun to set later, giving people more time to use natural daylight instead of artificial lights.

Keeping lights off for that extra hour cuts the U.S.'s electricity usage by about 1 percent per day. That's enough to light the homes and workplaces of roughly 3 million people each day, says David Prerau, a scientist who worked with Congress on the issue.
