At 2 a.m. (EST) March 10, the states that recognize Daylight Saving Time will “spring forward” and move their clocks one hour ahead.

While “springing forward” means losing an hour of sleep, the sun will be out for longer in the day.

The common wisdom about DST is that it is about farming, but it is not.

The history of DST goes back to World War I, when it was thought to save energy.

Following is a history of DST, and why some warmer states do not recognize it.

Thinkers — including Benjamin Franklin, New Zealand scientist George Hudson, and Englishman William Willett — advocated for plans that would give them more sunlight in the day, going all the way back to the 18th and 19th centuries.

The United States and several other European countries enacted DST during World Wars I and II as an energy-conservation measure, and kept it during peace-time.

Today, most of the U.S. — except for Hawaii, Arizona and many U.S. territories — all recognize DST.
