Eastern European Summer Time (EEST) is one of the names of UTC+03:00 time zone, 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.
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.
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 because it is convenient for areas in close commercial or other communication to keep the same time.
Coordinated Universal Time is the primary time standard by which the world regulates clocks and time. It is within about 1 second of mean solar time at 0° longitude, and is not adjusted for daylight saving time. In some countries where English is spoken, the term Greenwich Mean Time (GMT) is often used as a synonym for UTC and predates UTC by nearly 300 years.
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:
Belarus, officially the Republic of Belarus, formerly known by its Russian name Byelorussia or Belorussia, is a landlocked country in Eastern Europe bordered by Russia to the northeast, Ukraine to the south, Poland to the west, and Lithuania and Latvia to the northwest. Its capital and most populous city is Minsk. Over 40% of its 207,600 square kilometres (80,200 sq mi) is forested. Its major economic sectors are service industries and manufacturing. Until the 20th century, different states at various times controlled the lands of modern-day Belarus, including the Principality of Polotsk, the Grand Duchy of Lithuania, the Polish–Lithuanian Commonwealth, and the Russian Empire.
Bulgaria, officially the Republic of Bulgaria, is a country in Southeast Europe. It is bordered by Romania to the north, Serbia and North Macedonia to the west, Greece and Turkey to the south, and the Black Sea to the east. The capital and largest city is Sofia; other major cities are Plovdiv, Varna and Burgas. With a territory of 110,994 square kilometres (42,855 sq mi), Bulgaria is Europe's 16th-largest country.
Cyprus, officially the Republic of Cyprus, is an island country in the Eastern Mediterranean and the third largest and third most populous island in the Mediterranean, located south of Turkey, west of Syria and Lebanon, northwest of Israel and Palestine, north of Egypt, and southeast of Greece.
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.
Moscow is the capital and most populous city of Russia, with 13.2 million residents within the city limits, 17 million within the urban area and 20 million within the metropolitan area. Moscow is one of Russia's federal cities.
Samara Oblast is a federal subject of Russia. Its administrative center is the city of Samara. From 1935 to 1991, it was known as Kuybyshev Oblast. As of the 2010 Census, the population of the oblast was 3,215,532.
Russia, or the Russian Federation, is a transcontinental country in Eastern Europe and North Asia. At 17,125,200 square kilometres (6,612,100 sq mi), Russia is by a considerable margin the largest country in the world by area, covering more than one-eighth of the Earth's inhabited land area, and the ninth most populous, with about 146.79 million people as of 2019, including Crimea. About 77% of the population live in the western, European part of the country. Russia's capital, Moscow, is one of the largest cities in the world and the second largest city in Europe; other major cities include Saint Petersburg, Novosibirsk, Yekaterinburg and Nizhny Novgorod. Extending across the entirety of Northern Asia and much of Eastern Europe, Russia spans eleven time zones and incorporates a wide range of environments and landforms. From northwest to southeast, Russia shares land borders with Norway, Finland, Estonia, Latvia, Lithuania and Poland, Belarus, Ukraine, Georgia, Azerbaijan, Kazakhstan, China, Mongolia and North Korea. It shares maritime borders with Japan by the Sea of Okhotsk and the U.S. state of Alaska across the Bering Strait. However, Russia recognises two more countries that border it, Abkhazia and South Ossetia, both of which are internationally recognized as parts of Georgia.

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 and Romance Standard Time (RST), Paris Time or Rome 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, in order to make the most efficient use of seasonal daylight. It corresponds to the notion and practice of daylight saving time 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 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 permanently since 26 October 2014; before that date it had been set to UTC+04:00 year-round on 27 March 2011.
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).
Australia uses three main time zones: Australian Western Standard Time, Australian Central Standard Time, and Australian Eastern Standard Time. Time is regulated by the individual state governments, some of which observe daylight saving time (DST). Australia's external territories observe different time zones.
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.
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 Arabia Standard Time, Further-eastern European Time, Moscow 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 Kiev 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.
