Central European Summer Time (CEST, UTC+02:00), sometimes referred to as Central European Daylight Time (CEDT) [1] , is the standard clock time observed during the period of summer daylight-saving in those European countries which observe Central European Time (CET; UTC+01:00) during the other part of the year. It corresponds to UTC+02:00, which makes it the same as Eastern European Time, Central Africa Time, South African Standard Time, Egypt Standard Time and Kaliningrad Time in Russia. [2]

Names

Other names which have been applied to Central European Summer Time are Middle European Summer Time (MEST), [3] Central European Daylight Saving Time (CEDT), [4] and Bravo Time (after the second letter of the NATO phonetic alphabet). [5]

Period of observation

Since 1996, European Summer Time has been observed between 01:00 UTC (02:00 CET and 03:00 CEST) on the last Sunday of March, and 01:00 UTC on the last Sunday of October; previously the rules were not uniform across the European Union. [6]

There were proposals to abandon summer time in Europe from 2021, possibly by moving winter time up by an hour and keeping that time through the year. [7]

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.

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.

<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">Time in the Czech Republic</span>

Time in the Czech Republic is given by Central European Time and Central European Summer Time. Daylight saving time is observed from the last Sunday in March to the last Sunday in October. The Czech Republic has observed Central European Time since 1979. Until 1993 when Czechoslovakia was separated into the Czech Republic and Slovakia, they also had Central European Time and Central European Summer Time. After the summer months, time in the Czech Republic is shifted back by one hour to Central European Time. Like most states in Europe, Summer time is observed in the Czech Republic, when time is shifted forward by one hour, two hours ahead of Greenwich Mean Time.

<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.

Switzerland uses Central European Time (CET) during the winter as standard time, which is one hour ahead of Coordinated Universal Time (UTC+01:00), and Central European Summer Time (CEST) during the summer as daylight saving time, which is two hours ahead of Coordinated Universal Time (UTC+02:00).

Bosnia and Herzegovina uses a single time zone, denoted as Central European Time. It also observes summer time, shifting to Central European Summer Time.

<span class="mw-page-title-main">Time in Spain</span> Time zones in Spain

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.

Time in the Kingdom of the Netherlands is denoted by Central European Time during the winter as standard time in the Netherlands, which is one hour ahead of coordinated universal time (UTC+01:00), and Central European Summer Time (CEST) during the summer as daylight saving time, which is two hours ahead of coordinated universal time (UTC+02:00). The Caribbean Netherlands – which consist of the islands of Bonaire, Sint Eustatius and Saba – all observe Atlantic Standard Time (AST) year-round, which is four hours behind coordinated universal time (UTC−04:00).

<span class="mw-page-title-main">Time in Svalbard</span> Time zones used in Svalbard

Svalbard, an archipelago in the Arctic Ocean belonging to the Kingdom of Norway, uses Central European Time (CET) during the winter as standard time, which is one hour ahead of Coordinated Universal Time (UTC+01:00), and Central European Summer Time (CEST) during the summer as daylight saving time, which is two hours ahead of Coordinated Universal Time (UTC+02:00). This is shared with the rest of Norway, as is Svalbard's use of daylight saving time, which the territory observes annually by advancing the clock forward on the last Sunday in March and back again on the last Sunday in October. However, as Svalbard experiences midnight sun during the summer due to being located north of the Arctic Circle, it gives daylight saving time no utility, and is only observed in order to make communicating with Norway Proper more convenient. At the 74th parallel north, the midnight sun lasts 99 days and polar night 84 days, while the respective figures at the 81st parallel north are 141 and 128 days.

In Liechtenstein, the standard time is Central European Time. Daylight saving time is observed from the last Sunday in March to the last Sunday in October. Liechtenstein adopted CET in 1894.

<span class="mw-page-title-main">Time in Libya</span> Time zone used in Libya

Time in Libya is given by a single time zone, officially denoted as Eastern European Time. The zone is also known as Central Africa Time (CAT). Libya has observed EET since 5 November 2012, after it was announced in 2013 that Libya would be on permanent daylight saving time. Libya previously observed several different time zones as standard time and daylight saving time. For residents of western Libya, including Tripoli, solar time is usually one hour behind standard time.
