Central European Time


Central European Time
Time zones of Europe:
blue Western European Time (UTC+0)
Western European Summer Time (UTC+01:00)
light blue Western European Time (UTC+0)
red Central European Time (UTC+01:00)
Central European Summer Time (UTC+02:00)
yellow Eastern European Time (UTC+02:00)
Eastern European Summer Time (UTC+03:00)
orange Further-eastern European Time (UTC+03:00)
light green Moscow Time (UTC+04:00)
Light colours indicate countries that do not observe summer time: Algeria, Belarus, Iceland, Russia, Tunisia.

Central European Time (CET), used in most parts of the European Union, is a standard time that is 1 hour ahead of Coordinated Universal Time (UTC). The time offset from UTC can be written as +01:00. The same standard time, UTC+01:00, is also known under other names.[clarification needed]

The 15th meridian east is the central axis for UTC+01:00 in the world system of time zones.

As of 2011 all member states of the European Union observe summer time, those that use CET in winter use Central European Summer Time (CEST) daylight saving time in summer, with UTC+02:00.

Proposed adoption in the United Kingdom

The time around the world is based on Universal Coordinated Time (UTC) which is roughly synonymous with Greenwich Mean Time (GMT). From late March to late October, clocks in the United Kingdom are put forward by one hour for British Summer Time (BST). Since 1997, BST has been aligned with the European Union's standards for CET and other EU time zones. Central European Time is thus always one hour ahead of British time.

Since the late 1960s, particularly since the 1990s, there have been arguments about the benefits of changing to a system based on Central European Time.

In 1968 there was a three-year experiment when the UK and Ireland experimentally employed British Standard Time (GMT+1) all year round; clocks were put forward in March 1968 and not put back until October 1971.[clarification needed] This provided an opportunity to evaluate the impact of aligning with other EC countries on daylight change on a number of issues, particularly road casualties. The conclusions were not clear cut. A review by the UK Parliament found it was impossible to quantify the most important advantages and disadvantages, and concluded that a decision on whether to retain the new system would depend on a qualitative judgement. Nor was the experiment universally popular: opponents, particularly those based in Scotland, highlighted an increased number of road accidents (many involving children walking to school) in the dark winter mornings; however, the Royal Society for the Prevention of Accidents (RoSPA), a strong proponent of a change to Single/Double Summer Time (SDST) in Britain, which would in effect align the UK with CET, has pointed out that this rise was more than compensated for by reductions in casualties in the evening and that, in all, 2,500 deaths and serious injuries were saved in each year of the trial period.[1][2] Nevertheless, the UK Parliament voted by a large majority to discontinue the experiment.

Benefits of a switch to CET that have been cited by RoSPA and supported by other leading organisations such as the Confederation of British Industry include not only improvements to road casualty figures but also benefits to the environment, business, tourism, leisure, health and well-being, crime and the elderly. In 2010, a Private Members' Bill tabled in the UK Parliament by Conservative Member of Parliament Rebecca Harris, which proposes a move to Single/Double Summer Time, received its first reading in the House of Commons on 3 December 2010, when the lawmakers voted by 92 to 10 in support. However, the Bill is unlikely to be passed without Government support, and at the end of the Parliamentary debate concerning the Bill the government minister responsible for this area of policy, Ed Davey, said the government opposed the Bill, because "the necessary consensus across all parts of the UK does not yet exist to justify a change, or the passing of any legislation on the matter".[3] Strong feelings for and against the proposal had been expressed in the British media. Newspapers such as the Daily Express supporting it, but others, notably the Daily Mail, opposed it, in a rare occasion where these two conservative tabloids disagree.[citation needed]

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:

For other countries see UTC+1.

Discrepancies between official CET and geographical CET

Colour 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 winter
European summer

Legal, political and economic, as well as physical or geographical criteria are used in the drawing of time zones so official 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" 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 France and Germany even if they have the same time zone.[citation needed] 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

Areas between 7°30′ E and 22°30′ E ("physical" UTC+1), all using UTC+2

Areas located outside UTC+1 longitudes using UTC+1 time

Areas between 22°30′ W and 7°30′ W ("physical" UTC-1)

  • The westernmost part of mainland Spain (Galicia, e.g. the city of A Coruña); Cape Finisterre and nearby points in Galicia, at 9°18′ W, are the westernmost places where CET is applied.
  • The Norwegian island of Jan 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.

Areas between 7°30′ W and 7°30′ E ("physical" UTC)

Areas between 22°30′ E and 37°30' E ("physical" UTC+2)

  • More so, there exists a "tri-zone" point (where UTC+1, UTC+2, and UTC+4 meet) at the Norway-Finland-Russia tripoint near Nautsi. 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+4 (formerly 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+4 to UTC+2 to UTC+1.
