Central European Time ( CET) is a standard time which is 1 hour ahead of Coordinated Universal Time (UTC).
The time offset from UTC can be written as UTC+01:00.
It is used in most parts of Europe and in a few North African countries.
CET is also known as Middle European Time (MET, German: MEZ) and by colloquial names such as Amsterdam Time, Berlin Time, Brussels Time, Madrid Time, Paris Time, Rome Time, Warsaw Time or even Romance Standard Time (RST).
Time zones of Africa
The islands of Cape Verde are to the west of the African mainland. Mauritius and the Seychelles are to the east and north-east of Madagascar respectively.
15th meridian east is the central axis for UTC+01:00 in the world system of time zones.
As of 2011, all
member states of the European Union observe summer time ( daylight saving time), from the last Sunday in March to the last Sunday in October.
States within the CET area switch to Central European Summer Time (CEST, UTC+02:00) for the summer. 
UTC+01:00 is called West Africa Time (WAT), where it is used by several countries, year round.  Algeria, Morocco, and Tunisia also refer to it as Central European Time.  Usage Edit

Current usage Edit
As of 2017,
Central European Time is currently used in  Albania, Andorra, Austria, Belgium, Bosnia and Herzegovina, Croatia, Czech Republic, Denmark, France, Germany, Hungary, Italy, Liechtenstein, Luxembourg, Malta, Monaco, Montenegro, Netherlands, North Macedonia, Norway, Poland, San Marino, Serbia (including Kosovo, ), partially recognised as an independent country Slovakia, Slovenia, Spain (except Canary Islands), Sweden, Switzerland and Vatican City. 
History Edit 1884
1 October 1891
1 April 1893
1 November 1893
Luxembourg introduces CET, but leaves 1918.   1914
During World War I CET was implemented in all German-occupied territories.  1920
Lithuania adopts CET (but subsequently rescinded in 1940) and 1998−1999 again.  1922
Under German occupation:
 The Netherlands was switched from
UTC+00:20 to CET. Belgium was switched from
UTC+00:00. Luxembourg was switched from
UTC+00:00. France, which had adopted Paris time on 14 March 1891 and Greenwich Mean Time on 9 March 1911, was switched to CET.  Spain switched to CET. 
After World War II
Monaco, Andorra and Gibraltar implemented CET. 
Portugal used CET in the years 1966–1976 and 1992–1996.
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.
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. 
Central European Time is sometimes referred to as
continental time in the UK.
Other countries Edit
Several African countries use
UTC+01:00 all year long, where it is known as West Africa Time (WAT), although Algeria, Morocco and Tunisia use the term Central European Time despite being located in North Africa. 
Between 2005 and 2008,
Tunisia observed daylight saving time.  Libya also used CET during the years 1951–1959, 1982–1989, 1996–1997 and 2012–2013.

Discrepancies between official CET and geographical CET Edit
Legal time vs local mean time
1 h ± 30 m behind
0 h ± 30 m
1 h ± 30 m ahead
2 h ± 30 m ahead
3 h ± 30 m ahead
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" or "nominal"
UTC+01:00 time, actually use another time zone ( UTC+02:00 in particular – there are no "physical" UTC+01:00 areas that employ UTC+00:00). Conversely, there are European areas that have gone for UTC+01:00, even though their "physical" time zone is UTC (typically), UTC−01:00 (westernmost Spain), or UTC+02:00 (e.g. the very easternmost parts of Norway, Sweden, Poland and Serbia). On the other hand, people in Spain still have all work and meal hours one hour later than France and Germany despite sharing the same time zone. Historically  Gibraltar maintained UTC+01:00 all year until the opening of the land border with Spain in 1982, when it followed its neighbour and introduced CEST. The following is a list of such "incongruences":
Areas located within UTC+01:00 longitudes using other time zones Edit
These areas are located between 7°30′ E and 22°30′ E ("physical" UTC+1)
  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). 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 UTC+01:00 longitudes using UTC+01:00 time Edit
These areas are located either west of 7°30′ E or east of 22°30′ E (outside nominal
UTC+01:00)  
Areas between 22°30′ W and 7°30′ W (nominal UTC−01:00) 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 of CET in Spain. 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 entirety of Western Sahara with its western tip at 17°6′ W and its eastern tip at 8°40′ W.
Areas between 7°30′ W and 7°30′ E (nominal UTC+00:00) Edit
France, with the small exception of two separate easternmost parts of the mainland, one along eastern Alsace, incl. Strasbourg and the other in parts of the Alpes-Maritimes department, as well as the island of Corsica. Overseas departments of France use local times. 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
Netherlands The westernmost part of
Norway, incl. the cities of Bergen and Stavanger
Spain, except for the westernmost part of the mainland (see above) and the Canary Islands (which are further than 7°30′ W and use UTC+00:00).
Gibraltar The part of
Switzerland west of Bern (inclusive), also incl. cities such as Basel, Geneva, Lausanne, and Fribourg Most of Algeria including its capital Algiers.
Areas between 22°30′ E and 37°30′ E (nominal UTC+02:00) Edit 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 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. 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- Belarusian 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. See also Edit References Edit
