Western European Time (WET, UTC+0), defined legally as Greenwich Mean Time in the United Kingdom, is the time zone covering parts of western and northwestern Europe, and includes the following countries and regions:

Notably, it does not include France and Spain which use Central European Time (CET), even though both are mostly (France) or completely (Spain) west of 7.5E°. Note also the inclusion of Iceland and eastern Greenland, even though both are west of 15W°

During winter months, the countries above use WET, which corresponds to Greenwich Mean Time (GMT); however in the summer, most (but not all) of the above places move one hour ahead to Western European Summer Time (UTC+1).

There have been calls recently for the UK, particularly England and Wales, to change to CET. [1][2]

Historical uses

A slight variation of this time zone, based until 1911 on the Paris Meridian, was used in:

In the United Kingdom in years 1940-45 British Summer Time (BST=CET) was used in winters and in years 1941-45 & 1947 British Double Summer Time (BDST=CEST) was used in summers. Between 18 February 1968 and 31 October 1971 BST was used all year round.

In Ireland in years 1940-46 Irish Summer Time (IST=CET) was used all year (Ireland did not adopt similar time changes to British Double Summer Time (BDST=CEST) in 1941-45, 1947). Between 18 February 1968 and 31 October 1971 Irish Standard Time was used all year round.

In Portugal, CET was used in the periods 1966-1976 and 1992-1996.

In Africa Morocco uses WET.
