I’m so psyched. This Sunday starts daylight savings time. I’ve really been enjoying how the days have gradually been getting longer here in Boston, and now we’re going to take a big leap forward on Sunday. This is only the third year in which we set the clocks one hour ahead on the second Sunday of March instead of the first Sunday in April.

The change of start date was part of the federal Energy Policy Act adopted in 2005. Here in the U.S. daylight savings time originally began during World War I in an effort to conserve fuel used to generate artificial lighting. It was suspended after the war ended but reimplemented at the beginning of World War II. Today all states in the nation except Arizona and Hawaii observe daylight savings time, and many other countries also observe daylight savings time.
