In Turkey, time is given by UTC+03:00 year-round. This time is also called Turkey Time (TRT). The time at most is the same as in the Moscow Time and Arabia Standard Time zones. TRT was adopted by the Turkish Government on 8 September 2016. [1] It was also in use in Northern Cyprus until it reverted to Eastern European Time (EET) in October 2017. [2]

During some seasons (March–October), the TRT is also on the same time as Eastern European Summer Time. The IANA time zone identifier for Turkey is Europe/Istanbul. [3]

History

This postcard of the Constantinople General Post Office in 1909 features two clocks, one in Turkish time (alaturka saat ) and another in Western European time (alafranga saat ). Istanbul general post office 1909.jpg
This postcard of the Constantinople General Post Office in 1909 features two clocks, one in Turkish time (alaturka saat) and another in Western European time (alafranga saat).

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. [4] This necessitated adjusting the clocks daily, although tower clocks were only reset two or three times a week, [5] and the precise time varied from one location to another depending on latitude and longitude. [4]

The day was divided into two 12-hour periods, with the second 12:00 occurring at a "theoretical sunrise." [4] [5] 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. [5]

From 1927 to 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. [6] 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. [7] However, in October 2017, the Turkish government announced that starting 28 October 2018, the country would revert to EET, [8] but this sudden decision was reversed in November 2017. [9] In October 2018, a presidential decree announced that the UTC+03:00 would remain the year-round permanent time zone for the country. [10]

Today, during summers TRT time is the same as with the EEST (Eastern European Summer Time), while an hour ahead of EET (Eastern European Time) in winter and other the partial half of other seasons.

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. 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">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.

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">Central European Summer Time</span> Daylight saving time in the Central European time zone

Central European Summer Time, 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.

<span class="mw-page-title-main">Eastern European Summer Time</span> Daylight saving time zone used in Eastern Europe (UTC+3)

Eastern European Summer Time (EEST) is one of the names of the UTC+03:00 time zone, which is 3 hours ahead of Coordinated Universal Time. It is used as a summer daylight saving time in some European and Middle Eastern countries, which makes it the same as Arabia Standard Time, East Africa Time, and Moscow Time. During the winter periods, Eastern European Time (UTC+02:00) is used.

<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.

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

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.
