The clocks are changed back by one hour on the first Sunday in November in the United States. In 2025, this will happen on Sunday, November 2, at 2 a.m. local daylight time, when clocks will be set back to 1 a.m. standard time. This is the end of daylight saving time for the year, resulting in an earlier sunset and sunrise by an hour.
In Europe, including Germany and the UK, the clocks are set back earlier, on the last Sunday of October. For 2025, this will be on Sunday, October 26. The clocks will be set back one hour from 3 a.m. to 2 a.m. local time, marking the change from summer time (daylight saving time) to standard time.
