You know what spring means: Time to turn your clocks forward. That’s right, folks, Daylight Savings Time (DST 2013) will begin this weekend. Across most areas of the United States, people will be losing an hour of sleep due to the start of Daylight Savings Time. Officially, Daylight Savings Time 2013 begins this weekend on Sunday, March 10th, 2013 at 2:00 am. With the start of Daylight Savings Time, people will be turning their clocks ahead one full hour at 2:00 am on Sunday morning.

An easy way to distinguish the start of Daylight Savings Time from the end of it is the old mantra “spring forward, fall back.” In the spring (a.k.a this weekend), we must turn our clocks ahead one hour. While the lack of sleep is not favorable, the time change does mean we will get longer daylight hours in the evenings, inching closer and closer to summer.

While originally proposed by Benjamin Franklin as a way to save candles, Daylight Savings Time officially began in 1918. It was off again until 1942, when it was reinstalled during World War II to conserve energy, and then not celebrated past 1945.

The Uniform Time Act of 1966, however, made Daylight Savings Time a standard practice, delineating Daylight Savings Time to start on the last Sunday of April and end on the last Sunday in October, according to Discovery News.

The Energy Policy Act of 2005 changed those dates to 2 a.m. on both the second Sunday of March and the first Sunday in November each year, which we now currently observe.

Certain areas of the United States do not observe Daylight Savings Time and those areas include Arizona, Puerto Rico, Hawaii, the U.S. Virgin Islands and American Samoa.
