Daylight Saving Time begins
Published March 14, 2010
It’s that time again.
It is time to spring forward, a term used to help people remember to set their clocks forward one hour. Most Americans need to do that before going to bed on Saturday night.
Daylight Saving Time begins Sunday morning at 2 a.m. Its beginning is always on the second Sunday in March. It ends on the first Sunday in November when citizens set their clocks back to standard time.
The change to Daylight Saving Time is designed to help Americans conserve energy by taking advantage of the longer and later daylight hours. During the eight-month period the designation of time zones change. Central Standard Time becomes Central Daylight Saving Time.
DST began in the U.S. during World War I to take advantage of longer daylight hours between April and October. The theory was the change would save energy for war production.
While the change wasn’t mandatory after the war the federal government instituted the change again after the country entered World War II>
Since 2007 Daylight Saving Time is four weeks longer due to the passage of the Energy Policy Act in 2005. The federal government estimated the extension of DST by four weeks would save 10,000 barrels of fuel per day because businesses would use less power during daylight hours.
Arizona, Hawaii, Puerto Rico and the U.S. Virgin Islands do not observe Daylight Saving Time.
