When does the clock go back?

On 1 November 2026, residents across most of the United States are reminded that the official end of Daylight Saving Time is imminent. The transition back to Standard Time will occur officially at 2:00 a.m. local time on Sunday, 1 November 2026. At this precise moment, clocks should be set back one hour, effectively shifting the daylight from the evening hours to the morning. This biannual adjustment is mandated by the Uniform Time Act, which requires most states to observe the change, with notable exceptions including Hawaii and most of Arizona, which do not participate in the practice. While many modern electronic devices, such as smartphones and computers, are programmed to update automatically, manual timepieces and certain household appliances will require manual adjustment. As the nation prepares for the shift, public health officials and safety experts emphasize the importance of adjusting sleep schedules to mitigate the impact of the time change on circadian rhythms, while also noting that the extra hour of sleep is a primary benefit for many citizens.
