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.
As standard time (year-round)
- Principal cities: Istanbul, Moscow, Saint Petersburg, Doha, Riyadh, Baghdad, Nairobi, Dire Dawa, Addis Ababa, Manama, Sana'a, Aden, Minsk, Kuwait City, Asmara, Antananarivo, Kampala, Amman, Damascus
- Somaliland (disputed territory)
- South Africa
Arabia Standard Time
Arabia Standard Time, or AST (indicated by KSA on some Arabic TV stations), is used by some of the 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+04:00) but the government abolished DST in March 2008.
Arabia Standard Time is used by the following countries:
Most of European Russia, including Moscow, Saint Petersburg, Rostov-on-Don, Novaya Zemlya, Franz Josef Land. From October 26, 2014 Moscow and most other parts of European Russia started using UTC+03:00 again, year-round. Also on September 7, 2016, Turkey started using UTC+03:00 year-round. Besides the names mentioned above, the name "Eastern Europe Forward Time"' (EEFT) is sometimes used.

- Ukraine (standard time)
- The easternmost part, including Luhansk (the territories under Ukrainian control)
- The very easternmost part in the country
Areas outside UTC+03:00 longitudes using UTC+03:00 time
- The very east of Severny Island with 69°2' E as the easternmost point
Areas between 52°30' E and 67°30' E ("physical" UTC+04:00)
- Saudi Arabia
- The easternmost part of Sharqiyah

- The western part, including nation's capital Nairobi

- The westernmost point at UTC+03:00 is the westernmost point of contiguous Russia, near Lavry, Pskov Oblast (27°19' E). The time zone employed there (corresponding to 45°E) is 17°41' E of physical time, i.e. roughly 1 hour and 11 minutes ahead of physical time, making for the largest overall discrepancy between time used and physical time for UTC+03:00.
- The easternmost point at UTC+03:00 is Cape Zhelaniya, Severny Island, Novaya Zemlya, Russia (69°06' E). The time zone 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+03:00.
- On February 8, 2011, Russian president Dmitry Medvedev issued a decree cancelling daylight saving time in Russia. Under the decree, all clocks in Russia advanced by 1 hour on March 27, 2011, but did not change back the following October, effectively making Kaliningrad Time UTC+03:00 permanently, and Moscow Time UTC+04:00 permanently. This proved unpopular because of the dark mornings, children walking to school and people going to work in complete darkness. On October 26, 2014, Russia permanently returned to standard time by setting the clocks back by 1 hour effectively making Kaliningrad Time UTC+02:00 permanently and Moscow Time UTC+03:00 permanently.
- Ukraine had UTC+02:00 plus regularly EEST from 1990 till 2011 (in years 1981–1990 Moscow Summer Time) until the Ukrainian parliament added 1 hour "on the territory of Ukraine from March 27, 2011" and canceled daylight saving time on September 20, 2011, de facto making EEST (UTC+03:00) the new standard time. After strong criticism from the mass media, on 18 October 2011 the Ukrainian parliament cancelled its previous decision.
