Each year the clocks are moved back in autumn and moved forward again in spring, yet many of us still get caught out by an hour. The clocks moving forward in spring will mark the start of British summer as we move from Greenwich Mean Time to British Summer Time. When do the clocks go forward in 2025? The clocks always go forward at 1am on the final Sunday of March which this year falls on Sunday, March 30. The principal reason we change the clocks is to get the most out of the daylight.
