Daylight-saving time is arriving early (and staying longer), so set your clocks one hour ahead on Sunday, March 11.
Starting this year, daylight-saving time has been changed from its traditional calendar dates to a start three weeks earlier – Sunday, March 11 – and a finish one week later – Sunday, Nov. 4. Daylight-saving time is practiced in order to gain an extra hour of daylight during the early evening, resulting in the conservation of energy by substituting natural sunlight for electrical lighting.
According to The Old Farmer's Almanac, daylight-saving time first began in 1918 during World War I to allow for more evening light and save fuel for the war effort. Since then, daylight-saving time has been used on and off, with different start and end dates.
Benjamin Franklin first suggested the idea in 1784. It was later revived in 1907, when William Willett proposed a similar system in the pamphlet The Waste of Daylight. The Germans were the first to officially adopt the light-extending system in 1915, followed by the British, and in 1918 the United States, when Congress passed the Standard Time Act, establishing our time zones.
