The following countries, parts of countries, and territories use Eastern European Time all year round:
The following countries, parts of countries, and territories use Eastern European Time during the winter only:
- Bulgaria, since 1894
- Cyprus; Northern Cyprus used Further-eastern European Time for a year in 2016-17 and then reverted
- Estonia, in years 1921–40 and since 1990
- Finland, since 1921
- Greece, since 1916
- Israel, since 1948 (see also Israel Standard Time)

- Lithuania, in 1920–40 and since 1990 with break 1998–1999
- Moldova, in years 1918–40, 1941–44 and since 1991
- Ukraine, in years 1922–30 and since 1990
The following countries, parts of countries, and territories used Eastern European Time in the past:
Sometimes, due to its use on Microsoft Windows, FLE Standard Time (for Finland, Lithuania, Estonia, or sometimes Finland, Latvia, Estonia) or GTB Standard Time (for Greece, Turkey, Bulgaria) are used to refer to Eastern European Time.
Since political, in addition to purely geographical, criteria are used in the drawing of time zones, it follows that time zones do not precisely adhere to meridian lines. The EET (UTC+02:00) time zone, were it drawn by purely geographical terms, would consist of exactly the area between meridians 22°30' E and 37°30' E. As a result, there are European locales that despite lying in an area with a "physical" UTC+02:00 time, are in another time zone; likewise, there are European areas that have gone for UTC+02:00, even though their "physical" time zone is different from that. Following is a list of such anomalies:
Areas located outside UTC+02:00 longitudes using Eastern European Time (UTC+02:00) time
||Legal time vs local mean time
||1 h ± 30 m behind
||0 h ± 30 m
||1 h ± 30 m ahead
||2 h ± 30 m ahead
||3 h ± 30 m ahead
Areas west of 22°30' E ("physical" UTC+01:00) that use UTC+02:00
- The westernmost part of Greece, including the cities of Patras and Ioannina, and the Ionian Islands
- The very westernmost parts of the Bulgarian provinces of Vidin and Kyustendil
- The westernmost part of Romania, including most of the area of the counties of Caraș-Severin, Timiș (capital Timișoara), Arad, and Bihor, as well as the westernmost tips of the counties of Mehedinți and Satu Mare
- The extreme westernmost tip of Ukraine, near the border with Hungary and Slovakia, at the Ukrainian Transcarpathian Oblast (Zakarpattia Oblast), essentially comprising the city of Uzhhorod and its environs
- most of the Kaliningrad Oblast, including the cities of Kaliningrad and Baltiysk
- Western Lithuania, including the cities of Klaipėda, Tauragė, and Telšiai
- Western Latvia, including the cities of Liepāja and Ventspils
- The westernmost parts of the Estonian islands of Saaremaa and Hiiumaa, including the capital of the Saare County, Kuressaare
- The southwestern coast of Finland, including the city of Turku; also the Åland islands (of Finnish jurisdiction) – the Åland islands are the westernmost locale applying EET in the whole of Europe
- Most of Libya including the capital Tripoli
Areas east of 37°30' E ("physical" UTC+03:00) that use UTC+02:00
Areas located within UTC+02:00 longitudes (22°30' E – 37°30' E) using other time zones
These areas have sunrises and sunsets at least half an hour earlier than places on the UTC+01:00 meridian.
- The easternmost part of North Macedonia, including the city of Strumica.
- The absolutely easternmost part of Serbia, in the Pirot District, including the city of Pirot.
- The extreme easternmost tips of Hungary and Slovakia, bordering to the north and south respectively the Ukrainian Transcarpathian Oblast (Zakarpattia Oblast), a bit to the east of the Vásárosnamény, Hungary – Uzhhorod, Ukraine (both at 22°18' E) line
- The easternmost part of Poland, including the cities of Lublin and Białystok
- The extreme northeast of Sweden, in the Norrbotten province, including the cities of Kalix and Haparanda
- The northeast of Norway, lying north of Finland, roughly coinciding with the county of Finnmark. The easternmost town in Norway, Vardø, lies at 30°51' E, which is located east of even of the central meridian of UTC+02:00, i.e. east of Istanbul and Alexandria. The Norwegian-Russian border and Polish-Belorussian border are the only places where CET (UTC+1/+2) borders Moscow time (UTC+03:00), resulting in a one (or two in winter) hour time change when crossing that border. There is a "tri-zone" point (where UTC+01:00, UTC+02:00, and UTC+03:00 meet) at the Norway-Finland-Russia tripoint, near the town of Rayakoski.
- Belarus is located between 23°11′E and 32°47′E and is thus fully located with the physical UTC+02:00 area, but it uses UTC+03:00 year around.
- Practically all European Russia west of Moscow (except Kaliningrad Oblast); this includes the chunk of land from Murmansk all the way south to Belgorod, including the cities of St. Petersburg, Novgorod, and Pskov, to name only a few. (The westernmost point of contiguous Russia, near Lavry, Pskov Oblast, 27°19' E, is the westernmost point in European Russia where UTC+03:00 is applied.) This also includes the city of Anapa, at the westernmost tip of the Krasnodar Krai near the entrance to the Sea of Azov, at 37°22' E.
- Western Turkey.
Tripoints and borders between zones
- The Norway–Russia–Finland "tri-zone" point at Muotkavaara (see Central European Time) is surrounded by three different times in winter, two in summer. It had three time zones year-around before 2014.
- Two of the four tripoints of Belarus and the tripoint of the Kaliningrad Region are surrounded by three different times in winter.
