When Do the Clocks Go Back in 2033?
The clocks go back on Sunday, 30 October 2033, at 02:00 BST, ending British Summer Time for 2033.
The date
The autumn change in 2033 is on Sunday, 30 October 2033. At 02:00 BST the clocks fall back to 01:00 GMT, and the UK then stays on GMT until Sunday, 26 March 2034.
It falls a day before Halloween, so trick-or-treating on 31 October takes place in the dark an hour earlier by the clock than in the previous week.
Effects on daylight
On the Monday after the change, sunset in London comes at about 16:40 and in Edinburgh at about 16:25, compared with about 17:40 and 17:25 the week before. Sunrise in London moves from about 07:50 to about 06:50.
That is why many people describe the autumn change as the day when winter begins, even though it is still some weeks before the shortest day.
What to check
Devices update themselves, but ovens, car clocks and some watches do not. If you work with colleagues overseas, remember that India, Japan and Singapore do not change, so your gap with them grows by an hour.
