BANGOR, Maine (NEWS CENTER) -- It's that time of year again. On Sunday, Mainers will turn their clocks forward one hour for Daylight Saving Time. If you are wondering why we make this change twice a year, here is some information about the history of Daylight Saving Time in the United States.
Daylight Saving was first enacted into law by President Wilson in 1918 as a way to conserve energy during World War I. When the war ended, the popularity of Daylight Saving Time plummeted, mainly because on average people went to bed earlier and woke up earlier than we do today. It was so unpopular that Congress repealed daylight saving in 1919.
When the US entered World War II, President Roosevelt instituted "War Time," which brought back Daylight Saving Time again to conserve energy resources during the war. That lasted until 1945.
After the war, some states continued to use daylight saving, but it was not continued on a national level.
It wasn't until 1966 that another Daylight Saving Time law, the Uniform Time Act, was passed. The law made Daylight Saving Time a federally recognized act, but gave states the option not to observe it if they didn't want to.
President Nixon signed the Emergency Daylight Saving Time Energy Conservation Act, which made all states abide by daylight saving unless they made a special request not to due to environmental reasons.
Daylight Saving Time has remained a part of our yearly routine since then, though the day we change our clocks has shifted. The Energy Policy Act of 2005 extended Daylight Saving Time beginning in 2007. We now change the clocks on the second Sunday in March instead of on the first Sunday in April.
