British Summer Time was first established by the Summer Time Act 1916, after a campaign by builder William Willett. His original proposal was to move the clocks forward by 80 minutes, in 20-minute weekly steps on Sundays in April and by the reverse procedure in September. In 1916, BST began on 21 May and ended on 1 October. Willett never lived to see his idea implemented, having died in early 1915.
