When Do the Clocks Go Forward in 2033?
The clocks go forward on Sunday, 27 March 2033, at 01:00 GMT, starting British Summer Time for 2033.
The date and time
At 01:00 GMT on Sunday, 27 March 2033 the clocks jump to 02:00 BST. The night is an hour shorter, and the UK stays on BST until Sunday, 30 October 2033.
The date is the last Sunday of March, so it falls between 25 and 31 March. In 2033 it lands on 27 March, in the last week of the month.
What you lose, and what you gain
You lose an hour of sleep, but evenings are an hour lighter from that day. In London the sun sets at around 19:15 on the day of the change, and by the end of April it sets close to 20:00.
Mornings are darker, with sunrise at around 06:40 on the day of the change. In northern Scotland, where mornings are already late in winter, the first week of BST can feel especially dark in the morning.
Checklist
Change manual clocks, set heating timers, and check recurring meetings with the United States, which has usually already moved to summer time by this date, so the gap with the UK will be four hours for a few weeks before returning to five.
