Observance ofDST
DST is observed in parts of this time zone.
On the map; countries marked red in Africa use the West African Time zone (WAT) that is identical to the CET, because it is also based on the longitude 15° E

Central European Time (CET) is astandard time observed inCentral as well as parts ofWestern andSoutheast Europe, which is one hour ahead ofCoordinated Universal Time (UTC). Thetime offset from UTC can be written asUTC+01:00. It covers most of continentalEurope and it has been adopted by severalAfrican countries where it is known under various other names.

CET is also known asMiddle European Time (MET, German:MEZ) and by colloquial names that reference major European cities such asAmsterdam Time,Berlin Time,Brussels Time,Budapest Time,Madrid Time,Paris Time,Stockholm Time,Rome Time,Prague time,Warsaw Time orRomance Standard Time (RST).

The15th meridian east is the central axis perUTC+01:00 in the world system oftime zones.

Currently, allmember countries of theEuropean Union observe summer time (daylight saving time), from the last Sunday in March to the last Sunday in October.Countries within the CET area switch toCentral European Summer Time (CEST,UTC+02:00) for the summer.[1]The next change to CET will occur on 25 October 2026 (switching from 03:00 CEST to 02:00 CET).

In Africa,UTC+01:00 is calledWest Africa Time (WAT), where it is used by several countries, year round.[2]Algeria,Morocco, andTunisia also refer to it asCentral European Time.[3]

[edit]

As of 2017,[4] Central European Time is currently used inAlbania,Andorra,Austria,Belgium,Bosnia and Herzegovina,Croatia,Czechia,Denmark,France,Germany,Gibraltar (British territory),Hungary,Italy,Kosovo (partially recognised as an independent country),Liechtenstein,Luxembourg,Malta,Monaco,Montenegro,Netherlands,North Macedonia,Norway,Poland,San Marino,Serbia,Slovakia,Slovenia,Spain (except theCanary Islands),Sweden,Switzerland andVatican City.[3]

History

[edit]

After World War IIMonaco,Andorra andGibraltar implemented CET.[19]

Portugal used CET in the years 1966–1976 and 1992–1996.

United Kingdom

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

In 1968[23] there was a three-year experiment calledBritish Standard Time, when the UK andIreland experimentally employedBritish Summer Time (GMT+1) all year round; clocks were put forward in March 1968 and not put back until October 1971.[24]

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

Other countries

[edit]

Several African countries useUTC+01:00 all year long, where it is known asWest Africa Time (WAT), althoughAlgeria,Morocco andTunisia use the termCentral European Time despite being inNorth Africa.[3]

Between 2005 and 2008,Tunisia observeddaylight saving time.[25]Libya also used CET during the years 1951–1959, 1982–1989, 1996–1997 and 2012–2013.

For other countries seeUTC+01:00 andWest Africa Time.

The criteria for drawing time zones is based on many factors including: legal, political, economic, and physical or geographic. Consequently, 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 employUTC+00:00). Conversely, there are European areas that have gone forUTC+01:00, even though their "physical" time zone is UTC (typically),UTC−01:00 (westernmostSpain), orUTC+02:00 (e.g. the very easternmost parts ofNorway,Sweden,Poland andSerbia). On the other hand, people in Spain still usually have work and meal hours one hour later than France and Germany despite sharing the same time zone.[26] HistoricallyGibraltar maintainedUTC+01:00 all year until the opening of theland border with Spain in 1982, when it followed its neighbour and introduced CEST. The following is a list of such "incongruences":

Areas withinUTC+01:00 longitudes using other time zones

[edit]

These areas are between 7°30′ E and 22°30′ E ("physical" UTC+1)[27][28]

Areas usingUTC+02:00

[edit]

Areas outsideUTC+01:00 longitudes usingUTC+01:00 time

[edit]

These areas are either west of 7°30′ E or east of 22°30′ E (outside nominalUTC+01:00)[27][28]

Areas between 22°30′ W and 7°30′ W (nominalUTC−01:00)

[edit]
  • The westernmost part of mainlandSpain (Galicia, e.g. the city ofA Coruña);Cape Finisterre and nearby points in Galicia, at 9°18′ W, are the westernmost places of CET in Spain.
  • The Norwegian island ofJan 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.
  • WesternMorocco including the city ofCasablanca, at 7°35′ W. CET usage in Morocco extends as west as 13°10′ W.
  • The entirety ofWestern 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 (nominalUTC+00:00)

[edit]

Areas between 22°30′ E and 37°30′ E (nominalUTC+02:00)
