Since 22 October 1995, the starting and finishing times of daylight saving time across the European Union have been aligned--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 (or second Sunday when Easter fell on the third) and fourth Sunday in October . </P>
