Central European Time (
CET), used
in most
European and some
North African countries, 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 countries have adopted the use of
Central European Summer Time
(CEST)
daylight saving time in
summer, with
UTC+2.
Usage
Central European Time usage in Europe
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.
Portugal
used CET in the years 1966–76 and
1992–96.

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
, 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.
Areas located within UTC+1 longitudes using other time
zones

, near the border with Hungary

- The
northeast of Norway
, lying north
of Finland
, roughly coinciding with the county of Finnmark
; for instance Vadsø
, the
capital of Finnmark
, has a longitude of 23°49′ E. Actually, 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+2), i.e. east
of Istanbul
and Alexandria
. The sun reaches its highest point at
10:56 (when not DST).
The Norwegian
-Russian
border (incl. border passings such as Kirkenes
) is the only place where CET (UTC+1) borders Moscow
time (UTC+3), resulting in a two hours time change for the
passenger crossing that border.
More so, there exists a "tri-zone" point (where UTC+1, UTC+2, and
UTC+3 meet) at the Norway
-Finland
-Russia
tripoint
(look for the town of Nautsi in this map).
This is the only "tri-zone" point within Europe.
It is interesting to perform the following mental experiment when
looking at this map: Go to the westernmost point of the red area
(the Jäniskoski-Niskakoski area); this
belongs to Russian jurisdiction, hence the time there is
UTC+3.
Then, take a northeastern (NE) direction (that is an
eastwards direction); you will soon be crossing into
Finnish
territory, thus moving to the UTC+2 time
zone.
Continuing in that direction, you will eventually reach the
Finland
-Norway
border and
enter Norway
, thus
passing into the UTC+1 time zone.
So, moving in a (north–)easterly direction, you will be
moving from UTC+3 to UTC+2 to UTC+1.
