UTC+03:00 - 2011: Orange (DST Northern Hemisphere), Yellow (all year round), Light Blue - Sea areas
Time in Europe
Light colours indicate where standard time is observed all year; dark colours indicate where a summer time is observed.
Time in Africa
Light colours indicate where standard time is observed all year; dark colours indicate where daylight saving is observed.
Note: The islands of Cape Verde are to the west of the African mainland.
Time in the Middle East
Light colors indicate where standard time is observed all year; dark colors indicate where daylight savings is observed.
UTC+03:00 is an identifier for a time offset from UTC of +03. 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, 2018-05-21T11:04:57+03:00 (boldface only here to be clear).
Some areas in the world use UTC+03:00 all year, other areas only part of the year.
As standard time (all year round)
Principal cities: Istanbul, Moscow, Baghdad
Most of European Russia, including Moscow, St. Petersburg, Rostov-on-Don, Novaya Zemlya, Franz Josef Land. From October 26, 2014 Moscow and most other parts of European Russia started using UTC+3 again, all year around.  Also on September 7, 2016, Turkey started using UTC+3 all year round.
Besides the names mentioned above, the name 'Eastern Europe Forward Time' (EEFT) is sometimes used.
Arabia Standard Time
Arabia Standard Time, or AST (also known as KSA in some Arab TV stations), is used by some countries in the Middle East. As this time zone is predominantly in the equatorial region, there is no significant change in day length throughout the year, so daylight saving time is not observed. Between 1982 and 2007, Iraq observed Arabia Daylight Time (UTC+4) but the government abolished DST in March 2008.
Arabia Standard Time is used by the following countries:
- The easternmost point at which UTC+03 with no DST is applied is the easternmost point of Saudi Arabia, in the Eastern Province, at the border with Oman, with a longitude of roughly 55°20' E.
As daylight saving time (Northern Hemisphere summer only)
Principal cities: Kiev, Bucharest, Beirut
- The westernmost point at which UTC+03 with DST is applied is the westernmost point of contiguous Russia, near Lavry, Pskov Oblast (27°19' E). During the summer the time employed there (corresponding to 60°E) is 33°41' E of physical time, i.e. roughly 2 hours and 14 minutes ahead of physical time, making for the largest discrepancy between time used and physical time for UTC+3 with DST. This is the largest discrepancy overall for UTC+03 even if UTC+03 with no DST is included.
- The easternmost point at which UTC+03 with DST is applied is Cape Zhelaniya, Severny Island, Novaya Zemlya, Russia (69°06' E). During the winter the time employed there (corresponding to 45°E) is 24°06' W of physical time, i.e. roughly 1 hour and 36 minutes behind physical time, making for the largest discrepancy between time used and physical time for UTC+3 with DST for that time of the year, but not overall (see note 1 above).
- On February 8, 2011, Russian President Dmitry Medvedev issued a decree cancelling DST in Russia. Under the decree, all clocks in Russia will advance one hour on March 27, 2011, but will not change back the following October, effectively making Kaliningrad Time UTC+03 permanently, and Moscow Time UTC+04 permanently.
- Ukraine had UTC+2 plus regularly EEST from 1992 till 2011 (in years 1981–89 Moscow Summer Time) until the Ukrainian parliament added one hour "on the territory of Ukraine from March 27, 2011" and canceled DST on September 20, 2011 de facto making EEST (UTC+3) the new standard time. After strong criticism from the mass media, on 18 October 2011 the Ukrainian parliament cancelled its previous decision.
