The UK clocks go forward by one hour at 1am on the last Sunday of March each year, marking the start of British Summer Time (BST). This means one hour less sleep. The practice originated during World War One to make better use of daylight. Clocks then go back on the last Sunday of October, returning to Greenwich Mean Time (GMT).
