Since 2007, daylight savings time begins in the United States on the second Sunday in March — that means many of us will be “springing” forward in the early hours of March 14. On the second Sunday in March, in those areas of the U.S. that observe daylight savings time — which is most — clocks are set ahead one hour at 2 a.m. local standard time, which becomes  3 a.m. local daylight savings time. You will get the hour back on Nov. 7, when you “fall” back an hour to standard time.
