Central European Time (CET), is used in most parts of Europe and some North African countries.

It is a standard time, and is an hour ahead, of the English standardized, Coordinated Universal Time (UTC).

Usage[edit]

Useage in Africa[edit]

The CET correspondent to the African timezone West Africa Time.

Between 2005 and 2008, Tunisia observed daylight saving time.^[1]Libya also used CET during the years 1951–1959, 1982–1989, 1996–1997 and 2012–2013.

Usage in Europe[edit]

The monument 'The 15th Meridian' in Stargard, Poland

The majority of European countries use the CET, especially in the western Europe.

Current usage[edit]

Central European Time is currently (updated 2017)^[2] used in Albania, Andorra, Austria, Belgium, Bosnia and Herzegovina, Croatia, Czech Republic, Denmark, France, Germany, Hungary, Italy, Kosovo, Liechtenstein, Luxembourg, Macedonia, Malta, Monaco, Montenegro, Netherlands, Norway, Poland, San Marino, Serbia, Slovakia, Slovenia, Spain, Sweden and Switzerland.^[3]

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

Geographical discrepancies between used CET and "geographical CET"[edit]

European winter

European summer

Legal, political and economic, as well as physical or geographical criteria are used in the drawing of time zones so official time zones rarely adhere to meridian lines. The CET time zone, were it drawn by purely geographical terms, would consist of exactly the area between meridians 7°30′ E and 22°30′ E. As a result, there are European locales that despite lying in an area with a "physical" UTC+1 time, actually use another time zone (UTC+2 in particular – there are no "physical" UTC+1 areas that employ UTC). Conversely, there are European areas that have gone for UTC+1, even though their "physical" time zone is UTC (typically), UTC−1 (westernmost Spain), or UTC+2 (e.g. the very easternmost parts of Norway, Sweden, Poland and Serbia). On the other hand, the people in Spain still have all work and meal hours one hour later than France and Germany even if they have the same time zone.^[24] Following is a list of such "incongruences":

Historically Gibraltar maintained UTC+1 all year until the opening of the land frontier with Spain in 1982 when it followed its neighbour and introduced CEST.

Areas located within CET longitudes using other time zones[edit]

These areas are located between 7°30′ E and 22°30′ E ("physical" UTC+1)^[25][26]

Areas using UTC+2/CET+1[edit]

• The westernmost part of Greece, including the cities of Patras, Ioannina and the island of Corfu
  


• The westernmost parts of the Bulgarian provinces of Vidin and Kyustendil
  


• The westernmost part of Romania, including most of the area of the counties of Caraș-Severin, Timiș (capital Timișoara), Arad, and Bihor, as well as the westernmost tips of the counties of Mehedinți and Satu Mare
  


• The westernmost tip of Ukraine, near the border with Hungary and Slovakia, at the Ukrainian Transcarpathian Oblast (Zakarpattia Oblast), essentially comprising the city of Uzhhorod and its environs. (Although CET is used as local, non-official time in Transcarpathia).^{[citation needed]}


• Western Lithuania, including the cities of Klaipėda, Tauragė, and Telšiai
  


• Western Latvia, including the cities of Liepāja and Ventspils
  


• The westernmost parts of the Estonian islands of Saaremaa and Hiiumaa, including the capital of the Saare County, Kuressaare
  


• The southwestern coast of Finland, including the city of Turku; also the Åland islands (of Finnish jurisdiction) – the Åland islands are the westernmost locale applying EET in the whole of Europe


• The northwesternmost part of Finland, including Kilpisjärvi and Kaaresuvanto.


• The Russian exclave of Kaliningrad Oblast, excluding however its easternmost slice (the city of Nesterov is east of 22°30′ E, but that of Krasnoznamensk is not)

Areas located outside geographical CET longitudes using CET time[edit]

These areas are located west of 7°30′ E or east of 22°30′ E (outside "physical" UTC+1)^[25][26]

Areas between 22°30′ W and 7°30′ E (geographical ECT-1/"UTC")[edit]

• The westernmost part of mainland Spain (Galicia, e.g. the city of A Coruña); Cape Finisterre and nearby points in Galicia, at 9°18′ W, are the westernmost places where CET is applied.


• 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.

• Andorra


• Belgium


• 
  France, except for the absolutely easternmost part, in Alsace, incl. Strasbourg and parts of Alpes-Maritimes, and except for Corsica
  


• The very westernmost part of Germany, incl. the cities of Saarbrücken, Düsseldorf, Cologne, Aachen, and Trier
  


• The absolutely westernmost part of Italy, incl. the cities of Aosta in Aosta Valley and Cuneo in Piedmont
  


• Luxembourg


• Monaco


• Netherlands


• The westernmost part of Norway, incl. the cities of Bergen and Stavanger
  


• Mainland Spain, except for the westernmost part (see above) and Canary Islands.


• Gibraltar


• The part of Switzerland west of Bern (inclusive), also incl. cities such as Geneva, Lausanne, and Fribourg
  

Areas between 22°30′ E and 37°30′ E ("physical" UTC+2)[edit]

Map of Petsamo area in northern Finland/Soviet Union/Russia. The green area is the Finnish part of the Rybachi peninsula (Kalastajasaarento) which was ceded to the Soviet Union after the Winter War. The Red area is the Jäniskoski-Niskakoski area ceded to the USSR in 1947.

• The easternmost part of the Republic of 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 easternmost part of Poland, including the cities of Lublin and Białystok
  


• The northeast of Sweden, in the Norrbotten province, including the cities of Kalix and Haparanda
  


• The northeast of Norway, lying north of Finland, roughly coinciding with the county of Finnmark; for instance Vadsø, the capital of Finnmark, has a longitude of 29°49′ E. Actually, 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+2), i.e. east of Istanbul and Alexandria. The sun reaches its highest point at 10:56 (when not DST).
  The Norwegian–Russian and the Polish-Belarussian border are the only places where CET (UTC+1/+2) borders Moscow time (UTC+3), resulting in a two hours time change (or one hour in summer) for the travellers crossing that border.


• More so, there exists a "tri-zone" point (where UTC+1, UTC+2, and UTC+3 meet) at the Norway–Finland–Russia tripoint near Muotkavaara.
