United Kingdom

The time around the world is based on Universal Coordinated Time (UTC) which is roughly synonymous with Greenwich Mean Time (GMT). From late March to late October, clocks in the United Kingdom are put forward by one hour for British Summer Time (BST). Since 1997, most of the European Union aligned with the British standards for BST.

In 1968[24] there was a three-year experiment called British Standard Time, when the UK and Ireland experimentally employed British Summer Time (GMT+1) all year round; clocks were put forward in March 1968 and not put back until October 1971.[25]

Central European Time is sometimes referred to as continental time in the UK.

Several African countries use UTC+01:00 all year long, where it called West Africa Time (WAT), although Algeria, Morocco and Tunisia also use the term Central European Time, despite being located in North Africa.[3]

Between 2005 and 2008, Tunisia observed daylight saving time.[26] Libya also used CET during the years 1951–1959, 1982–1989, 1996–1997 and 2012–2013.

For other countries see UTC+01:00 and West Africa Time.

• The Norwegian island of Jan Mayen lies entirely within this area and extends nearly as far west as Cape Finisterre, with its western tip at 9°5′ W and its eastern tip at 7°56′ W.
• Western Morocco including the city of Casablanca, at 7°35′ W. CET usage in Morocco extends as west as 13°10′ W.

• The easternmost part of North Macedonia, including the city of Strumica
• The easternmost part of Serbia, in the Pirot District, including the city of Pirot, and small easternmost parts of Bor District.
• The easternmost tips of Hungary and Slovakia, bordering to the north and south respectively the Ukrainian Transcarpathian Oblast (Zakarpattia Oblast), a bit to the east of Vásárosnamény, Hungary – Uzhhorod, Ukraine (both at 22°18′ E) line

• The northeast of Norway, lying north of Finland, roughly coinciding with the county of Finnmark. The easternmost town in Norway, Vardø, lies at 30°51′ E, which is so far east, so as to be east even of the central meridian of EET (UTC+02:00), i.e. east of Istanbul and Alexandria. The sun reaches its highest point at 10:56 (when not DST), although the sun does not vary so much in height at the latitude 70°N.
  The Norwegian–Russian and the Polish-Belarussian border are the only places where CET (UTC+1/+2) borders Moscow time (UTC+03:00), resulting in a two hours time change (or one hour in summer) for the travellers crossing that border.
• There is a "tri-zone" point (where UTC+01:00, UTC+02:00, and UTC+03:00 meet, winter times) at the Norway–Finland–Russia tripoint near Muotkavaara. During the summer Finland and Russia both have UTC+03:00.
