Are you ready to set your clocks back an hour? Daylight Saving Time ends this Sunday, November 2, at 2 a.m.
Daylight Saving Time is "the practice of moving the clocks forward one hour from Standard Time during the summer months, and changing them back again in the fall," according to Almanac.com.
A few people suggested the idea before DST was ever implemented - Benjamin Franklin and an Englishman named William Willet. Franklin wanted residents to save candlelight, while Willet noted that people "appreciate the long, light evenings. Everyone laments their shrinkage as the days grow shorter." His proposal to move clocks ahead was met with ridicule.
DST was finally established in World War I, when the U.S. needed to preserve energy. The time change lasted only about seven months, after opposition from dairy farmers. It was reestablished in World War II, again to save fuel.
After WWII, Daylight Saving Time was used inconsistently among the states, until finally Congress passed the Uniform Time Act in 1966, establishing the consistent use of DST.
Now, Americans "spring forward" on the second Sunday in March and "fall back" on the second Sunday of November.
All American states practice Daylight Saving Time, except Hawaii and Arizona. Seven states have "approved legislation to make daylight saving time permanent." Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands also do not observe the time changes, according to USA Today.
The Associated Press reports that 7 in 10 Americans prefer not to switch back and forth.
Daylight saving time will return next year on March 8.
