Central European Time

Central European Time (CET), used in most of Europe, is one of the names of the time zone that is 1 hour ahead of Coordinated Universal Time (UTC), with a time offset of UTC+1 (in winter).

Most European countries have adopted the use of Central European Summer Time (CEST) daylight saving time in summer, with UTC+2.

Exact Central European Time on 15th meridian (Trebnje, Slovenia)

The German Empire unified its time zones in 1893, to use CET (MEZ). During the war, this time was implemented in all occupied territories.

Before World War II, Lithuania used CET (MET) in the years 1920–40. In France, Belgium, Netherlands and Luxembourg CET was kept. After the war Monaco, Spain, Andorra and Gibraltar implemented CET.

Ireland and the United Kingdom experimentally adopted CET in the years 1968–71; however, this experiment proved unpopular and short-lived, mainly due to the increased number of road accidents (many involving children walking to school) in the dark winter mornings.[citation needed] Portugal used CET in the years 1966–76 and 1992–96.

[edit] Central European Summer Time

The following countries and cities have introduced the use of Central European Summer Time between 1:00 UTC on the last Sunday of March, and 1:00 UTC on the last Sunday of October:

[edit] Discrepancies between official CET and geographical CET

Color 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

European summer

Since legal, political and economic, in addition to purely physical or geographical, criteria are used in the drawing of time zones, it follows that official time zones do not precisely adhere to meridian lines. The CET (UTC+1) 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 e.g. France and Germany even if they have the same time zone. 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.
