How long have we been using daylight savings time?

Benjamin Franklin came with the idea for daylight saving time back in 1784, but nobody put the concept into practice until World War I. During World War I, many countries started adjusting their clocks during part of the year. The idea was to try to adjust daylight hours in the summer to more closely match the hours that people are awake. During World War I, the goal was to conserve fuel by lowering the need for artificial light. The United States and several other countries still use some variation on this system. In the United States, by an act of Congress, daylight-saving time starts on the first Sunday in April and ends on the last Sunday in October. Clocks are advanced one hour in the spring and moved back one hour in the fall ("spring forward, fall back" is a phrase many people use to remember this). You lose an hour in the spring and get it back in the fall
