{{Time zones of Europe}}
'''Western European Time''' ('''WET''', [[UTC±00:00]]) is a [[time zone]] covering parts of western [[Europe]] and consists of countries using [[UTC±00:00]] (also known as [[Greenwich Mean Time]], abbreviated GMT).<ref>{{Cite web|url=http://www.europarl.europa.eu/RegData/etudes/STUD/2017/611006/EPRS_STU(2017)611006_EN.pdf|title=EU summer-time arrangements under Directive 2000/84/EC|last=|first=|date=2017|website=|publisher=[[European Parliament]]|url-status=live|archive-url=|archive-date=|access-date=}}</ref><ref name=":0">{{Cite web|url=http://www.europarl.europa.eu/RegData/docs_autres_institutions/parlements_nationaux/com/2018/0639/UK_HOUSE-OF-LORDS_AVIS-COM(2018)0639_EN.pdf|title=Reasoned opinion on subsidiarity|last=|first=|date=2019|website=|publisher=Committee on Legal Affairs – [[European Parliament]]|url-status=live|archive-url=|archive-date=|access-date=}}</ref> It is one of the three standard time zones in the [[European Union]] along with [[Central European Time]] and [[Eastern European Time]].<ref>{{Cite web|url=https://ec.europa.eu/transport/themes/summertime_en|title=Seasonal clock change in the EU|first=|date=2016-09-22|website=[[European Commission]]|language=en|url-status=live|archive-url=|archive-date=|access-date=2019-11-18}}</ref><ref name=":0" />

The nominal span of the UTC±00:00 time zone is 7.5°E to 7.5°W (0° ± 7.5°), but does not include the [[Netherlands]], [[Belgium]], [[Luxembourg]], [[France]], [[Gibraltar]] or [[Spain]] (except Canary Islands) which use [[Central European Time]] (CET) even though these are mostly or completely west of 7.5°E. Conversely, Iceland and eastern Greenland use UTC±00:00 although both are west of 7.5°W. In September 2013, a [[Spain|Spanish]] parliamentary committee recommended switching to UTC±00:00.<ref>[https://www.bbc.co.uk/news/world-europe-24294157 "Spain considers time zone change to boost productivity".] ''BBC News''. 27 September 2013.</ref><ref>Hamilos, Paul (26 September 2013).

Until the [[Second World War]], France used UTC±00:00. However, the [[German occupation of France during World War II|German occupation]] switched France to German time, and it has remained in CET since then.<ref>{{cite journal|last=Poulle|first=Yvonne|title=La France à l'heure allemande|journal=Bibliothèque de l'école des chartes|year=1999|volume=157|issue=2|pages=493–502|url=http://www.persee.fr/articleAsPDF/bec_0373-6237_1999_num_157_2_450989/article_bec_0373-6237_1999_num_157_2_450989.pdf|archive-url=https://web.archive.org/web/20150904024453/http://www.persee.fr/articleAsPDF/bec_0373-6237_1999_num_157_2_450989/article_bec_0373-6237_1999_num_157_2_450989.pdf|url-status=dead|archive-date=4 September 2015|accessdateaccess-date=11 January 2012|doi=10.3406/bec.1999.450989}}</ref> Two other occupied territories, [[Belgium]] and the [[Netherlands]], did the same, and Spain also switched to CET in solidarity with Germany under the orders of [[Francisco Franco|General Franco]].<ref>{{Cite news|url=https://www.npr.org/sections/parallels/2013/11/30/244995264/spains-been-in-the-wrong-time-zone-for-seven-decades?t=1543530349805|title=Spain Has Been In The 'Wrong' Time Zone For 7 Decades|work=NPR.org|access-date=2018-11-29|language=en}}</ref>
 
In the United Kingdom, from 1940 to 1945 [[British Summer Time]] (BST=[[Central European Time|CET]]) was used in winters, and from 1941 to 1945 and again in 1947, British Double Summer Time (BDST=[[Central European Summer Time|CEST]]) was used in summers. Between 18 February 1968 and 31 October 1971, [[British Summer Time|BST]] was used all year round.<ref>{{Cite web|url=https://www.timeanddate.com/time/zone/uk/london?year=1968|title=Time Zone & Clock Changes 1960-1969 in London, England, United Kingdom|website=www.timeanddate.com|language=en|access-date=2018-11-29}}</ref><ref>{{Cite web|url=https://www.timeanddate.com/time/zone/uk/london?year=1971|title=Time Zone & Clock Changes 1970-1979 in London, England, United Kingdom|website=www.timeanddate.com|language=en|access-date=2018-11-29}}</ref>
