The clock changes depend on your location. Here are the common recent updates you’ll likely need:

• United Kingdom and Ireland: Clocks go forward one hour on the last Sunday in March at 1:00 a.m. local time (BST to IST), and go back one hour on the last Sunday in October at 2:00 a.m. BST (back to GMT). For 2025, that means:
  • March change: 1:00 a.m. on Sunday, March 30, 2025 (forward to BST)
  • October change: 2:00 a.m. on Sunday, October 26, 2025 (back to GMT) [UK guidelines apply to BST/GMT cycle]
• Most of continental Europe: Clocks go forward on the last Sunday in March and back on the last Sunday in October, at 1:00 a.m. UTC+1 (CEST) in spring, and 1:00 a.m. UTC+2 (CEST) in autumn, effectively shifting one hour.
• Sweden and many Nordic countries align with the European schedule: DST begins on the last Sunday in March and ends on the last Sunday in October; clocks move forward in the early hours of Sunday and move back in autumn.
• United States and Canada (outside Atlantic regions): DST ends at 2:00 a.m. local time on the first Sunday in November (fall back) and begins at 2:00 a.m. on the second Sunday in March (spring forward) in most regions that observe DST.

How to confirm for you quickly:

• If you tell me your country or city, I can give you the exact date and time for the local clock change this year and the next.
• If you’re traveling, consider checking a local time website or your device’s automatic time zone updates, as some regions have debated or changed DST rules in recent years.
