Daylight Saving Time Ends on November 3, 2024

Americans will set their clocks back one hour, marking the shift to standard time with earlier sunsets and lighter mornings.

Daylight saving time will officially end at 2 a.m. on Sunday, November 3, when clocks are set back one hour.
Most U.S. states observe this change, though Arizona and Hawaii remain on standard time year-round.
The practice originally aimed to conserve energy during World War I and was standardized in 1966 under the Uniform Time Act.
Critics argue that the time change disrupts sleep patterns and daily routines, with some advocating for permanent standard time.
Automatic devices like phones will adjust the time on their own, but manual clocks should be set back before going to bed on November 2.
