It's time to "spring ahead" on Sunday. That's right: Daylight Saving Time begins three weeks early this year -- at 2am on Sunday, March 11. Be sure to set your clocks ahead before you go to bed that night.

The beginning of Daylight Saving Time is also a perfect time to replace the batteries in your home's life-saving devices, including smoke alarms and carbon monoxide detectors.
