UTC+00:00 is an identifier for a time offset from UTC of +00:00. This time zone is the basis of Coordinated Universal Time (UTC) and all other time zones are based on it. In ISO 8601, an example of the associated time would be written as 2069-01-01T12:12:34+00:00. It is also known by the following geographical or historical names:

Notes:

  1. The westernmost point where UTC with DST is applied is El Hierro, Canary Islands, Spain (18°00′ W). Time used there is 2 hours and 12 minutes ahead of physical time in the summer, making for the greatest discrepancy in the UTC time zone.
  2. The easternmost settlement where UTC with DST is applied is Lowestoft in Suffolk, East Anglia, UK (at just 1°45′ E).
  3. Morocco normally observes UTC+01:00, but the clock is set back one hour during Ramadan. See Time in Morocco for further information.
  4. Whilst de facto Ireland operates on the same time as the United Kingdom, its de jure basis to do so differs. Whereas standard time in the UK is GMT in winter and BST (daylight saving time) in summer, Irish Standard Time (UTC+01:00) is observed in summer and GMT is used in winter. For details, see below.

Notes:

  1. The westernmost point where UTC with no DST is applied is Bjargtangar, at the northwest peninsula of Iceland (24°32′ W). Time used there is 1 hour and 38 minutes ahead of physical time. This is the greatest deviation from physical time for UTC+00:00 with no DST.

Since legal, political, social and economic criteria, in addition to physical or geographical criteria, are used in the drawing of time zones, actual time zones do not precisely adhere to meridian lines. The UTC+00:00 time zone, were it determined purely by longitude, would consist of the area between meridians 7°30′W and 7°30′E. However, in much of Western and Central Europe, despite lying between those two meridians, UTC+01:00 is used; similarly, there are European areas that use UTC, even though their physical time zone is UTC−01:00 (e.g. most of Portugal), or UTC−02:00 (the westernmost part of Iceland). Because the UTC+00:00 time zone in Europe is at its western edge, Lowestoft in the United Kingdom, at only 1°45′E, is the easternmost settlement in Europe in which UTC+00:00 is applied.

Greenwich Mean Time (GMT) is the local mean time at the Royal Observatory in Greenwich, London, counted from midnight. At different times in the past, it has been calculated in different ways, including being calculated from noon; as a consequence, it cannot be used to specify a particular time unless a context is given. The term "GMT" is also used as one of the names for the time zone UTC+00:00 and, in UK law, is the basis for civil time in the United Kingdom.

<span class="mw-page-title-main">Time zone</span> Area that observes a uniform standard time

A time zone is an area which observes a uniform standard time for legal, commercial and social purposes. Time zones tend to follow the boundaries between countries and their subdivisions instead of strictly following longitude, because it is convenient for areas in frequent communication to keep the same time.

Western European Summer Time is a summer daylight saving time scheme, 1 hour ahead of Greenwich Mean Time and Coordinated Universal Time. It is used in:

<span class="mw-page-title-main">Central European Time</span> Standard time (UTC+01:00)

Central European Time (CET) is a standard time of Central, and parts of Western Europe, which is one hour ahead of Coordinated Universal Time (UTC). The time offset from UTC can be written as UTC+01:00. It is used in most parts of Europe and in a few North African countries. CET is also known as Middle European Time and by colloquial names such as Amsterdam Time, Berlin Time, Brussels Time, Budapest Time, Madrid Time, Paris Time, Rome Time, Prague time, Warsaw Time or Romance Standard Time (RST).

<span class="mw-page-title-main">Western European Time</span> Time zone in Europe equal to UTC

Western European Time is a time zone covering parts of western Europe and consists of countries using UTC±00:00. It is one of the three standard time zones in the European Union along with Central European Time and Eastern European Time.

<span class="mw-page-title-main">Summer time in Europe</span> Variation of standard clock time

Summer time in Europe is the variation of standard clock time that is applied in most European countries in the period between spring and autumn, during which clocks are advanced by one hour from the time observed in the rest of the year, with a view to making the most efficient use of seasonal daylight. It corresponds to the notion and practice of daylight saving time (DST) to be found in some other parts of the world.

<span class="mw-page-title-main">Eastern European Time</span> Time zone in Eastern Europe (GMT +2)

Eastern European Time (EET) is one of the names of UTC+02:00 time zone, 2 hours ahead of Coordinated Universal Time. The zone uses daylight saving time, so that it uses UTC+03:00 during the summer.

<span class="mw-page-title-main">Daylight saving time by country</span>

Daylight saving time (DST), also known as summer time, is the practice of advancing clocks during part of the year, typically by one hour around spring and summer, so that daylight ends at a later time of the day. As of 2024, DST is observed in most of Europe, most of North America and parts of Africa and Asia around the Northern Hemisphere summer, and in parts of South America and Oceania around the Southern Hemisphere summer. It was also formerly observed in other areas.

Spain has two time zones. Spain mainly uses CET (UTC+01:00) in Peninsular Spain, Ceuta, Melilla and the plazas de soberanía. In the Canary Islands, the time zone is WET (UTC±00:00).

<span class="mw-page-title-main">Time in the Danish Realm</span>

Denmark, including its dependencies of Faroe Islands and Greenland, uses six time zones.

Time in Guinea-Bissau is given by a single time zone, denoted as Greenwich Mean Time. Guinea-Bissau shares this time zone with several other countries, including fourteen in western Africa. Guinea-Bissau does not observe daylight saving time (DST).
