It is the time of year again. On March 11, people will need to set their clock one hour ahead at 2 a.m. local standard time.
Each year Daylight Saving Time begins on the second Sunday in March and ends on the first Sunday in November. According to the U.S. Naval Observatory website, DST was adopted by Germany during World War I to save energy for the war effort.
However, not all areas -- like Hawaii and most of Arizona -- use this method.
The site also reads that from 1945 to 1996, there were no uniform rules for DST in the US. This caused confusion for trains, buses and the broadcasting industry.
After many revision, the current schedule has been followed since 2007 by the Energy Policy Act of 2005.
The theory behind DST is that people would save more energy if America “spring forward,” according to USNO.
It is thought that Americans would spend less time in their cars in the evening, which would cause fewer accidents, and more people would enjoy an extra hour of daylight by doing outdoor activities. However this theory is debatable, the U.S Department of Energy shows that DST only reduces 0.003 percent of energy while another study shows that it possibly increases energy consumptions because air conditioning is used more during the summer months.
The time will “fall back” November 4.
