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.
Since 1996, European Summer Time has been observed from the last Sunday in March to the last Sunday in October. Previously, the rules were not uniform across the European Union.
The following countries and territories use Eastern European Summer Time during the summer:
In one year 1991 EEST was used also in Moscow and Samara time zones of Russia. Egypt has previously used EEST in 1957–2010 and 2014–2015. Turkey, has previously used EEST in 1970–1978, EEST and Moscow Summer Time in 1979–1983, and EEST in 1985–2016.

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 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), 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 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+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.
Israel Summer Time, also in English, Israel Daylight Time (IDT) is the practice in Israel by which clocks are advanced by one hour, beginning on the Friday before the last Sunday of March, and ending on the last Sunday of October.
Israel Standard Time (IST) is the standard time zone in Israel. It is two hours ahead of UTC (UTC+02:00).
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.
Further-eastern European Time (FET) is a time zone defined as three hours ahead of UTC (UTC+03:00) without daylight saving time, the zone immediately higher than the Eastern European Time. As of September 2016, it is used in Belarus, western Russia and Turkey, and is also called Minsk Time, Moscow Time (MSK), or Turkey Time (TRT).
Egypt Standard Time is UTC+02:00, which is exactly the same as Eastern European Time, Central Africa Time and South African Standard Time, and is co-linear with neighboring Libya and Sudan. Egypt has previously used Eastern European Summer Time (UTC+03:00), during the summer periods from 1957–2010 and 2014–15.
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.
Time in Ukraine is defined as UTC+02:00 and in summer as UTC+03:00. Locally it is referred to as the Kyiv Time and is part of the Eastern European Time. The change for the summer time take place in the last week of March at 03:00 when the time changes an hour ahead and the last week of October at 04:00 when the time changes an hour back; this way the clocks in Ukraine are 1 hour ahead of those in central Europe at all times.
As of 2017, daylight saving time is used in the following Asian countries:
Denmark, including the dependencies Faroe Islands and Greenland, uses six different time zones.
Time in Cyprus is given by Eastern European Time (EET) (UTC+02:00) or Eastern European Summer Time (EEST) (UTC+03:00) during the summer.
Time in Turkey is given by UTC+03:00 year-round. This time is also called Turkey Time (TRT) or Türkiye Saati İle (TSİ). The time is currently same as in the Arabia Standard Time, Further-eastern European Time and Moscow Time zone. Turkey Time was adopted by the Turkish government on September 8, 2016. It was also in use in the Turkish Republic of Northern Cyprus until it reverted to EET in October 2017.
Estonia uses Eastern European Time (EET) (UTC+02:00) during winter, and Eastern European Summer Time (EEST) (UTC+03:00) during summer. Estonia has observed daylight saving time since 1981. However, it wasn't used in 1989-1996 and 2000–2002.
