when was daylight saving introduced in the uk
British Summer Time 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.[6] In 1916, BST began on 21 May and ended on 1 October.[7] Willett never got to see his idea implemented, for he died in early 1915.
