The UK clocks go back by one hour at 2am on the last Sunday of October, ending British Summer Time and returning to Greenwich Mean Time. This means one extra hour of sleep but noticeably darker evenings. The date shifts each year because it is anchored to the last Sunday of the month, not a fixed calendar date.
