Time in Switzerland

Last updated

Switzerland uses a single time zone, denoted as Central European Time (CET: UTC+01:00). Switzerland also observes summer time, shifting to Central European Summer Time (CEST: UTC+02:00). [1]

Daylight saving time

Whilst DST was introduced in much of Western Europe in the spring of 1980, Switzerland did not implement DSL until the following year. This resulted in there being a one hour time difference between Switzerland and most of Western Europe, including all of the bordering countries (with the exception of Liechtenstein) for around six months in 1980.

The German village of Büsingen am Hochrhein, a small exclave, entirely surrounded by Swiss territory, did not implement DSL in 1980 either and observed the same time as Switzerland, meaning there was a one hour time difference between this village and the rest of Germany. The zone Europe/Busingen was created in the 2013a release of the tz database, [2] because since the Unix time epoch in 1970, Büsingen has shared clocks with Zurich. [3]

Since 1981 the shifts to DST occur on the date as specified for European Summer Time. Historically DST was observed in 1941 and in 1942.

Solar time

The difference of longitude between the western and easternmost points of Switzerland is equivalent to 4°32′09″, resulting in a difference of approximately 18 minutes of solar time.

IANA time zone database

The IANA time zone database contains one zone for Switzerland in the file zone.tab, named Europe/Zurich. Columns marked with * are the columns from zone.tab itself.

Time zone Region on Earth that has a uniform standard time for legal, commercial, and social purposes

A time zone is a region of the globe that observes a uniform standard time for legal, commercial and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions instead of strictly following longitude because it is convenient for areas in close commercial or other communication to keep the same time.

Daylight saving time Time adjustment practice

Daylight saving time (DST), also daylight savings time or daylight time and summer time, is the practice of advancing clocks during warmer months so that darkness falls later each day according to the clock. The typical implementation of DST is to set clocks forward by one hour in the spring and set clocks back by one hour in autumn to return to standard time. In other words, there is one 23-hour day in late winter or early spring and one 25-hour day in the autumn.

Western European Summer Time daylight savings time zone

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 standard time (UTC+01:00)

Central European Time (CET), used in most parts of Europe and a few North African countries, is a standard time which is 1 hour ahead of Coordinated Universal Time (UTC). The time offset from UTC can be written as UTC+01:00. The same standard time, UTC+01:00, is also known as Middle European Time and under other names like Berlin Time, Warsaw Time, Paris Time or Rome Time.

Western European Time time zone

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 variation of standard clock time that is applied in most European countries in the period between spring and autumn

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 many other parts of the world.

Central European Summer Time daylight savings time in the central european time zone

Central European Summer Time (CEST), sometime referred also as Central European Daylight Time (CEDT), is the standard clock time observed during the period of summer daylight-saving in those European countries which observe Central European Time (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 and Kaliningrad Time in Russia.

Moscow Time zone time

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.

Time in Russia About the 11 zones of Russia

There are eleven time zones in Russia, which currently observe times ranging from UTC+02:00 to UTC+12:00. Daylight saving time is not used in Russia. From 27 March 2011 to 26 October 2014, permanent DST was used.

Time in Brazil standard timezone in Brazil, equivalent to UTC-03:00

Time in Brazil is calculated using standard time, and the country is divided into four standard time zones: UTC−02:00, UTC−03:00, UTC−04:00, UTC−05:00 and UTC−06:00.

Time in the United Kingdom

The United Kingdom uses Greenwich Mean Time or Western European Time (UTC) and British Summer Time or Western European Summer Time (UTC+01:00).

Time in Germany Germany uses CET/CEST

The time zone in Germany is 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 doubled hour during the switch back to standard time is named 2A and 2B.

Central European Midsummer Time

Central European Midsummer Time (CEMT) was a time zone three hours ahead of GMT, used as a double summer time in several European countries during the 1940s.

Time in the Czech Republic

Time in the Czech Republic is 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.

Time in Antarctica

Antarctica sits on every line of longitude, due to the South Pole being situated on the continent. Theoretically, Antarctica would be located in all time zones; however, areas south of the Antarctic Circle experience extreme day-night cycles near the times of the June and December solstices, making it difficult to determine which time zone would be appropriate. For practical purposes time zones are usually based on territorial claims; however, many stations use the time of the country they are owned by or the time zone of their supply base. Nearby stations can have different time zones, due to their belonging to different countries. Many areas have no time zone since nothing is decided and there are not even any temporary settlements that have any clocks. They are simply labeled with UTC time.

Daylight saving time in Asia

As of 2017, daylight saving time is used in the following Asian countries:

Time in Portugal overview about the time zones in Portugal

Portugal has two time zones and observes daylight saving time. Continental Portugal and Madeira use UTC+00:00, while the Azores use UTC–01:00. Daylight saving time is observed nationwide from the last Sunday in March to the last Sunday in October, so that every year, continental Portugal and Madeira temporarily use UTC+01:00, and the Azores temporarily use UTC+00:00.

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

Time in Spain Time zones in Spain

Spain has two time zones and observes daylight saving time. Spain mainly uses Central European Time (GMT+01:00) and Central European Summer Time (GMT+02:00) in Peninsular Spain, the Balearic Islands, Ceuta, Melilla and plazas de soberanía. In the Canary Islands, the time zone is Western European Time (GMT±00:00) and Western European Summer Time (GMT+01:00). Daylight saving time is observed from the last Sunday in March to the last Sunday in October throughout Spain.

Time in the Netherlands

In the Netherlands, the standard time is Central European Time (UTC+01:00). Daylight saving time is observed from the last Sunday in March to the last Sunday in October.
