Clocks go back by one hour on the last Sunday of October at 2:00 am local time in the UK (BST to GMT) for 2025, which falls on October 26, 2025. In the US, daylight saving ends on Sunday, November 2, 2025, at 2:00 am local time, when clocks roll back one hour. This means you gain an extra hour of sleep that weekend in both regions, with evenings becoming darker earlier afterward.
