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.
The easternmost settlement where UTC with DST is applied is Lowestoft in Suffolk, East Anglia, UK (at just 1°45′ E).
Morocco normally observes UTC+01:00, but the clock is set back one hour during Ramadan. See Time in Morocco for further information.
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.

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.

Countries and areas west of 22°30′W ("physical" UTC−02:00) that use UTC+00:00

The westernmost part of Iceland, including the northwest peninsula (the Westfjords) and its main town of Ísafjörður, which is west of 22°30′W, uses UTC+00:00. Bjargtangar, Iceland is the westernmost point in which UTC is applied.

Countries and areas west of 7°30′W ("physical" UTC−01:00) that use UTC+00:00

In Europe

Canary Islands (Spain)
Most of Portugal, including Lisbon, Porto, Braga, Aveiro, and Coimbra. (Only the easternmost part, including cities such as Bragança and Guarda, lies east of 7°30′W.) Madeira, at 17°W even further west, also employs UTC+00:00.
The western half of Ireland, including the cities of Cork, Limerick, and Galway

Extreme westerly portion of the Outer Hebrides, in the west of Scotland; for instance, Vatersay, an inhabited island and the westernmost settlement of Great Britain, lies at 7°54′W. If uninhabited islands or rocks are taken into account St Kilda, west of the Outer Hebrides, at 8°58′W, and Rockall, at 13°41′W, should be included.

Countries that use UTC+01:00 as the basis for standard time although local solar time would suggest UTC+00:00

In Europe

Spain (except for the Canary Islands, which use UTC+00:00). Much of Galicia (and far western fringes of Extremadura and Andalusia) lie west of 7°30′W ("physical" UTC−01:00), whereas there is no Spanish territory that even approaches 7°30′E (the boundary of "physical" UTC+01:00). Spain's time is the direct result of Generalissimo Franco's presidential order (published in Boletín Oficial del Estado of 8 March 1940)^[2] abandoning Greenwich Mean Time and advancing clocks one hour, effective from 23:00 on 16 March 1940. This is an excellent example of political criteria used in the drawing of time zones: the time change was passed "in consideration of the convenience from the national time marching in step according to that of other European countries".^[3]^[4] The presidential order (most likely enacted to be in synchrony with Nazi Germany and Fascist Italy, with which the Franco regime was unofficially allied) included in its 5th article a provision for its future phase out,^[4] which never took place. Due to this political decision Spain is two hours ahead of its local mean time during the summer, one hour ahead in winter.^[5]
Andorra
Belgium
Most of France, including the cities of Paris, Marseille and Lyon. Only small parts of Alsace, Lorraine and Provence are east of 7°30′E ("physical" UTC+1).

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:

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).

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.

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.

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.

Moscow Time is the time zone for the city of Moscow, Russia, and most of western Russia, including Saint Petersburg. It is the second-westernmost of the eleven time zones of Russia. It has been set to UTC+03:00 without DST since 26 October 2014; before that date it had been set to UTC+04:00 year-round on 27 March 2011.

UTC−02:00 is an identifier for a time offset from UTC of −02:00.

UTC+10:00 is an identifier for a time offset from UTC of +10:00. This time is used in:

UTC−01:00 is an identifier for a time offset from UTC of −01:00.

UTC+01:00 is an identifier for a time offset from UTC of +01:00. In ISO 8601, the associated time would be written as 2019-02-07T23:28:34+01:00. This time is used in:

UTC+09:00 is an identifier for a time offset from UTC of +09:00.

UTC+02:00 is an identifier for a time offset from UTC of +02:00. In ISO 8601, the associated time would be written as 2020-11-08T23:41:45+02:00. This time is used in:

UTC+03:00 is an identifier for a time offset from UTC of +03:00. In areas using this time offset, the time is three hours later than the Coordinated Universal Time (UTC). Following the ISO 8601 standard, a time with this offset would be written as, for example, 2019-02-08T23:36:06+03:00.

Time in Chile is divided into three time zones. Most of Continental Chile uses the time offset UTC−04:00 in winter time and UTC−03:00 in summer time, while the Magallanes and Chilean Antarctica region uses the time offset UTC−03:00 the whole year. Additionally, Easter Island uses the time offset UTC−06:00 in winter time and UTC−05:00 in summer time.

Europe spans seven primary time zones, excluding summer time offsets. Most European countries use summer time and harmonise their summer time adjustments; see Summer time in Europe for details.

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 and observes daylight saving time. Spain mainly uses CET (UTC+01:00) and CEST (UTC+02:00) in Peninsular Spain, Ceuta, Melilla and the plazas de soberanía. In the Canary Islands, the time zone is WET (UTC±00:00) and WEST (UTC+01:00). DST is observed from the last Sunday in March to the last Sunday in October throughout Spain.

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