Europe spans 7 primary time zones (from UTC−01:00 to UTC+05:00), excluding summer time offsets (4 of them can be seen on the map to the right, with 1 further-western zone containing the Azores, and 2 further-eastern zones spanning Georgia, Azerbaijan, eastern territories of European Russia, and the European part of Kazakhstan). Most European countries use summer time and harmonise their summer time adjustments. See Summer time in Europe for details.
