When does daylight saving time end and we 'fall back'?
Fall has already begun, with the autumnal equinox on Thursday, Sept. 22.
That marked the minute when the sun will be directly above the equator, making day and night nearly equal in length across the world, according to NASA.
There’s another important date ahead as well – the end of daylight saving time.
Daylight saving time will end – meaning we will “fall back” by moving our clocks back one hour – at 2 a.m. Sunday, Nov. 6. The change shifts more daylight hours into the morning.
Not every state recognized daylight saving time meaning there’s no need to change the clocks in Arizona and Hawaii. For almost everyone else, it’s a time to change the clocks before bed on Sunday and get ready for dark afternoons.
It will stay that way until Sunday, March 12, 2023 when daylight saving time starts again and we move clocks ahead one hour. It will end Nov. 5, 2023.
The twice-a-year ritual of changing the clocks back and forth dates back to World War I as the U.S. looked to conserve energy to assist the war effort. The practice wasn’t made permanent in the U.S. until 1973, when President Richard Nixon signed the Emergency Daylight Saving Time Energy Conservation Act. In 2005, the Uniform Time Act tweaked that schedule by setting the start of daylight saving time to the second Sunday of March and the end on the first Sunday of November, lengthening the duration of DST.
