The clocks are set back one hour to end daylight saving time on Sunday, October 26, 2025, at 3:00 AM local daylight time. At this time, the clocks are turned backward one hour to 2:00 AM local standard time, giving an extra hour of sleep and causing sunrise and sunset to occur about an hour earlier than the day before.
In the UK, this change occurs at 2:00 AM on the same date, October 26, 2025.
In the United States, however, daylight saving time ends a bit later, on Sunday, November 2, 2025, at 2:00 AM when clocks go back to 1:00 AM.
Thus, the exact date and time when clocks are set back an hour depends on the country and region.
