Time in Europe
Light colours indicate where standard time is observed all year; dark colours indicate where a
summer time is observed.
During British Summer Time (BST),
civil time in the
Portugal is advanced one hour forward of
Greenwich Mean Time (GMT) (in effect, changing the time zone from
UTC+0 to UTC+1), so that evenings have more daylight and mornings have less.
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
 – 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.
