Daylight Saving Time (DST) begins at 2 a.m. March 8 and will end at 2 a.m. Nov. 1.

Remember to set you clock ahead one hour.

Most states — except Arizona and Hawaii — observe DST, which the federal government doesn’t mandate to states.

DST also is practiced in most European countries.

The U.S. passed a law standardizing the daylight saving time start and end dates in 1918.
