Daylight Saving Time ends in the United States on Sunday, Nov. 3, at 2 a.m.
You will be setting your clock back one hour, following the adage of “spring forward, fall back.” The “extra” hour gives you a chance to catch up on the sleep you lost in March when the clocks moved forward and daylight saving time began.
How Daylight Saving Got its Start In an effort to save resources during World War II, the U.S. made daylight saving time mandatory for the whole country. And it was observed the entire year. Now it's optional for states, so, for example, if you travel from California to Arizona in the winter, you'll lose an hour.
However, the idea has been around about as long as the United States itself. Benjamin Franklin first suggested daylight saving time in 1748. Before it was widely adopted in the 1970s, countries — and even neighboring cities — phased the change in gradually.
