Clocks go back on Sunday, October 25 as British Summer Time ends

Summarised from 2 outlets · Updated 20 Oct, 14:57 · Archive

The clocks will go back one hour at 2am on Sunday, October 25, marking the end of British Summer Time.

At 2am on Sunday, October 25, clocks across the UK will go back one hour to 1am, marking the end of British Summer Time and the return to Greenwich Mean Time. The change will give people an extra hour in bed.

Modern devices such as smartphones and smartwatches will adjust automatically. Analogue clocks and traditional wristwatches will require manual adjustment. The Palace of Westminster's clockmakers must recalibrate the Great Clock in Elizabeth Tower, along with approximately 2,000 other timepieces across the parliamentary estate.

The shift will have an immediate effect on evening daylight. In London, sunset will fall to approximately 4:46pm on the day of the change, a significant drop from the 6:12pm recorded days earlier. Sunset times vary across the UK: Lowestoft, in the east, will see the sun set at around 4:37pm, while County Fermanagh in Northern Ireland will not experience a pre-5pm sunset until October 30. Morning brightness will increase, with sunrise occurring at approximately 7am instead of 8am after the change.

The UK will remain on Greenwich Mean Time until the clocks spring forward again at the end of March.
