when do the clocks go forward in the united kingdom
British Summer Time BST begins at 01:00 GMT on the last Sunday of March and ends at 01:00 GMT (02:00 BST) on the last Sunday of October. Since 22 October 1995, the starting and finishing times of daylight saving time across the European Union have been aligned[3] â€“ for instance Central European Summer Time begins and ends on the same Sundays at exactly the same time (that is, 02:00 CET, which is 01:00 GMT). Between 1972 and 1995, BST began and ended at 02:00 GMT on the third Sunday in March and fourth Sunday in October.[4]
History of timekeeping devices During the Middle Ages, clocks primarily served religious purposes; the first employed for secular timekeeping emerged around the 15th century. In Dublin, the official measurement of time became a local custom, and by 1466 a public clock stood on top of the Tholsel (the city court and council chamber).[115] It was the first of its kind to be clearly recorded in Ireland, and would only have had an hour hand.[115] The increasing lavishness of castles led to the introduction of turret clocks.[116] A 1435 example survives from Leeds castle; its face is decorated with the images of the Crucifixion of Jesus, Mary and St George.[116]
