Time in Turkey is given by UTC+03:00 year-round. This time is also called Turkey Time (TRT). The time is currently the same as in the Arabia Standard Time and Moscow Time zones. Turkey Time was adopted by the Turkish Government on 8 September 2016.It was also in use in the Turkish Republic of Northern Cyprus until it reverted to Eastern European Time (EET) in October 2017.
Until 1927, "Turkish time" (or alla turca time or ezânî time) referred to the system of setting the clocks to 12:00 midnight at sunset.This necessitated adjusting the clocks daily, although tower clocks were only reset two or three times a week, and the precise time varied from one location to another depending on latitude and longitude. The day was divided into two 12-hour periods, with the second 12:00 occurring at a "theoretical sunrise." In practice, the Turkish railroads used both Turkish time (for public schedules) and eastern European time (for actually scheduling the trains), and government telegraph lines used St. Sophia time (i.e., Paris time + 1:47:32) for international telegrams.
Until 2016, Turkey used Eastern European Time (EET) in the winter (UTC+02:00) and Eastern European Summer Time (EEST) (UTC+03:00) during the summer.The date for transition between standard time and daylight saving time generally followed EU rules, but had variations in some years. In 2016, the decision to stay on UTC+03:00 year-round was enacted. In October 2017, the Turkish government announced that starting 28 October 2018, the country would revert to EET, but this decision was reversed in November 2017. In October 2018, a presidential decree announced that UTC+03:00 would remain the year-round permanent time zone for the country.
Japan Standard Time, or Japan Central Standard Time, is the standard time zone in Japan, 9 hours ahead of UTC. Japan does not observe daylight saving time, though its introduction has been debated on several occasions. During World War II, the time zone was often referred to as Tokyo Standard Time.
The Eastern Time Zone (ET) is a time zone encompassing part or all of 23 states in the eastern part of the United States, parts of eastern Canada, the state of Quintana Roo in Mexico, Panama, Colombia, mainland Ecuador, Peru, and a small portion of westernmost Brazil in South America, along with certain Caribbean and Atlantic islands.
Central European Time (CET) 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. 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, Madrid Time, Paris Time, Rome Time, Warsaw Time or even 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 many 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.
Central European Summer Time (CEST), sometimes referred to 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 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.
The Atlantic Time Zone is a geographical region that keeps standard time—called Atlantic Standard Time (AST)—by subtracting four hours from Coordinated Universal Time (UTC), resulting in UTC−04:00. AST is observed in parts of North America and some Caribbean islands. During part of the year, some portions of the zone observe daylight saving time, referred to as Atlantic Daylight Time (ADT), by moving their clocks forward one hour to result in UTC−03:00. The clock time in this zone is based on the mean solar time of the 60th meridian west of the Greenwich Observatory.
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.
There are eleven time zones in Russia, which currently observe times ranging from UTC+02:00 to UTC+12:00. Daylight saving time (DST) has not been used in Russia since 26 October 2014. From 27 March 2011 to 26 October 2014, permanent DST was used.
East Africa Time, or EAT, is a time zone used in eastern Africa. The time zone is three hours ahead of UTC (UTC+03:00), which is the same as Moscow Time, Arabia Standard Time, Further-eastern European Time and Eastern European 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.
As of 2017, daylight saving time is used in the following Asian countries:
Denmark, including the dependencies Faroe Islands and Greenland, uses six time zones.
Finland uses Eastern European Time (EET) during the winter as standard time and Eastern European Summer Time (EEST) during the summer as daylight saving time. EET is two hours ahead of coordinated universal time (UTC+02:00) and EEST is three hours ahead of coordinated universal time (UTC+03:00). Finland adopted EET on 30 April 1921, and has observed daylight saving time in its current alignment since 1981 by advancing the clock forward one hour at 03:00 EET on the last Sunday in March and back at 04:00 EET on the last Sunday in October, doing so an hour earlier for the first two years.
In Greece, the standard time is Eastern European Time. Daylight saving time, which moves one hour ahead to UTC+03:00 is observed from the last Sunday in March to the last Sunday in October. Greece adopted EET in 1916.
In Bulgaria, the standard time is Eastern European Time. Daylight saving time, which moves one hour ahead to UTC+03:00 is observed from the last Sunday in March to the last Sunday in October, inline with most EU member states.
In Romania, the standard time is Eastern European Time. Daylight saving time, which moves one hour ahead to UTC+03:00 is observed from the last Sunday in March to the last Sunday in October.
Time in Lithuania is given by Eastern European Time. Daylight saving time, which moves one hour ahead to UTC+03:00 is observed from the last Sunday in March to the last Sunday in October. Latvia adopted EET in 1920.
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 permeant daylight saving time. Libya previously observed several different time zones as standard time and daylight saving time.
