British summer time
British Summer Time or BST is the civil time during the summer months in the United Kingdom during which the clocks are advanced from Greenwich mean time by one hour. It was first established by the Summer Time Act of 1916, was amended by subsequent acts and is now defined by the Summer Time Order of 2002 which laid down that it would be
...the period beginning at one o'clock, Greenwich mean time, in the morning of the last Sunday in March and ending at one o'clock, Greenwich mean time, in the morning of the last Sunday in October.
—The Summer Time Order 2002[1]
BST was introduced during World War I as an energy-saving measure. During World War II, a further hour was added to establish British Double Summer Time or BSDT.[2]
