You know the old saying, "spring ahead, fall back"...
Set your clocks ahead 1 hour Sunday 2AM
It's time to spring ahead!
Daylight saving time 2012 officially begins this Sunday, March 10 at 2:00AM (local time) -- remember to set your clocks ahead one hour to 3:00AM when you go to bed Saturday night.
It's also the perfect time to install a fresh battery in your smoke detectors.
About Daylight Saving Time
Daylight saving time (DST) — aka summer time is the practice of temporarily advancing clocks during the summertime so that afternoons have more daylight and mornings have less. Clocks are adjusted forward one hour near the start of spring and are adjusted backward in autumn.
Most of the United States and Canada observe DST beginning the second Sunday in March and ending the first Sunday in November -- almost two-thirds of the year.
