Since 1995 October 22, all member states of the European Union have used a common date and time for the beginning and end of the summer time period, i.e., the period of the year during which the clocks are put forward by 60 minutes compared with the rest of the year.

The Ninth Directive 2000/84/EC states that from 2002 onwards, in every Member State, the summer-time period shall begin at 1.00 a.m. Greenwich Mean Time on the last Sunday in March, and shall end at 1.00 a.m. Greenwich Mean Time on the last Sunday in October.
