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.
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 from 1957–2010 and 2014–2015. Turkey, has previously used EEST from 1970-1978 EEST, Moscow Summer Time from 1979–1983, and EEST from 1985-2016.

Central Africa Time, or CAT, is a time zone used in central and southern Africa. Central Africa Time is two hours ahead of Coordinated Universal Time (UTC+02:00), which is the same as the adjacent South Africa Standard Time and Eastern European Time (although the latter area uses Eastern European Summer Time (UTC+3) most of the year)
As this time zone is in the equatorial and tropical regions, there is little change in day length throughout the year, and so daylight saving time is not observed.
Central Africa Time is used by the following countries:
Egypt (observes Eastern European Time)
Democratic Republic of the Congo (eastern)
ZimbabweThe following countries use South African Standard Time instead of Central Africa Time:
EswatiniCentral European Summer Time
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.East Africa Time
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.As this Time Zone is predominantly in the equatorial region, there is no significant change in day length throughout the year and so daylight saving time is not observed.East Africa Time is used by the following countries:
UgandaEastern European Time
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.
A number of African countries use UTC+02:00 all year long, where it is called Central Africa Time (CAT), although Egypt and Libya also use the term Eastern European Time.Egypt Standard Time
Egypt Standard Time is UTC+2, which is exactly the same as Eastern European Time, and is co-linear with neighboring Libya and Sudan. Egypt has previously used Eastern European Summer Time (UTC+3), during the summer periods from 1957–2010 and 2014–15.Iran Standard Time
Iran Standard Time (IRST) or Iran Time (IT) is the time zone used in Iran. Iran uses a UTC offset UTC+03:30. IRST is defined by the 52.5 degrees east meridian, the same meridian which defines the Iranian calendar and is the official meridian of Iran.
Between 2005 and 2008, by decree of President Mahmoud Ahmadinejad, Iran did not observe daylight saving time (called Iran Daylight Time or IRDT). It was reintroduced from 21 March 2008.Time in Cyprus
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.In 2016, Northern Cyprus had different time to Southern Cyprus during the winter, meaning it followed Turkey which starting summer 2016 has UTC+3 all year around. From autumn 2017 it has same time as Southern Cyprus, that means DST during summer but not winter. That is a different time compared to Turkey during the winter.Time in Lebanon
Time in Lebanon 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
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.Time in Ukraine
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 (Ukrainian: Київський час, Kyivskyi chas) 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.
