During British Summer Time (BST), civil time in the United Kingdom is advanced one hour forward of Greenwich Mean Time (GMT), in effect changing the time zone from UTC+00:00 to UTC+01:00, so that mornings have one hour less daylight, and evenings one hour more.

BST begins at 01:00 GMT every year on the last Sunday of March and ends at 02:00 BST on the last Sunday of October. The starting and finishing times of daylight saving were aligned across the European Union on 22 October 1995, and the UK retained this alignment after it left the EU; both BST and Central European Summer Time begin and end on the same Sundays at 02:00 Central European Time, 01:00 GMT.
