Many Americans will spring forward an hour to mark the beginning of daylight savings time (DST)âalso known as daylight saving timeâat 2 a.m. on Sunday, March 8. Time will fall back to standard time again on Sunday, November 1, when DST ends.
Daylight saving time is observed in many countries all over the world, though the time frame for it varies. In the United States, it ran from the last Sunday in April to the first Sunday in October until the Energy Policy Act was passed in 2005. As of 2007, daylight saving now runs from the second Sunday in March until the first Sunday in November.
