The clocks will be set back one hour on Sunday, November 2, 2025, at 2:00 a.m. local time. This marks the end of daylight saving time in most parts of the United States, when the time shifts back to standard time, giving an extra hour of sleep. In the UK and much of Europe, the clocks go back earlier, on the last Sunday in October, which in 2025 is October 26.
