About Clocks Go Back (UK & EU) 2027
At 02:00 BST the clock returns to 01:00 GMT in the United Kingdom, and the European Union leaves Central European Summer Time for standard time. You get an extra hour in bed, and from that morning the sun rises an hour earlier on the clock.

Safety campaigns in the UK treat this date as the start of the darker months, with higher pedestrian risk in the late afternoon. It is also the weekend when train timetables, shift rotas and pharmacy opening hours are re-cut, and when phones and laptops quietly fix themselves overnight.
- You gain an hour of sleep, which is why this is the easier of the two changes.
