At 2 a.m. on Sunday, Nov. 5, clocks in most of the United States will “fall back” one hour, ending daylight saving time for the year. Although this process has become as smooth a clockwork for many, daylight saving time has had an interesting and chaotic history.
In the U.S., Congress has expanded the length of daylight saving multiple times, and even briefly experimented with year-round daylight saving.
Some states do not in participate daylight saving time, and many countries don’t either. Russia briefly tried year round daylight saving time, before abolishing it and remaining on standard time permanently.
