Overview

• The UK returns to Greenwich Mean Time at 2 a.m. on Sunday, Oct. 26, moving clocks back one hour from British Summer Time.
• In the United States, daylight saving time ends at 2 a.m. local time on Sunday, Nov. 2, with Arizona and Hawaii not observing the change.
• Most phones, computers, and other internet-connected devices will update automatically, but analog watches, car dashboards, ovens, and standalone alarms may need manual resets.
• Turning clocks back shifts sunrise and sunset an hour earlier, and recent studies and sleep-medicine experts say permanent standard time would offer the greatest health benefits compared with daylight saving time or twice-yearly switches.
• Public interest in ending the biannual change remains high, with a YouGov poll reporting 65% in favor, yet legislative efforts have stalled and nationwide policy in the U.S. remains unchanged; next switches are March 29, 2026 in the UK and March 8, 2026 in the U.S.
