UTC+03:00 ~ 45 degrees E – all year
|Central||45 degrees E|
|Western border (nautical)||37.5 degrees E|
|Eastern border (nautical)||52.5 degrees E|
|Date-time group (DTG)||C|
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, 2014-09-06T01:03:33+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.

Further-eastern European Time (FET)
Since September 2011 the following areas in Eastern Europe use UTC+3 all year round:
Besides the names mentioned above, the name 'Eastern Europe Forward Time' (EEFT) is sometimes used.
From October 26, 2014, Moscow and most other parts of European Russia will start using UTC+3 again, all year around. 
Arabia Standard Time
Arabia Standard Time, or AST, 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. Arabia Standard Time is used by the following countries:
- The westernmost point at which UTC+03 with no DST is applied is the Russian town of Baltiysk, in the Kaliningrad Oblast, at 19°55′E. Before 27 March 2011, it was the westernmost point of Sudan, in the West Darfur state, at the border with Chad; Geneina, the capital of West Darfur, located very close to that point, has a longitude of 22°27' E.
- The easternmost point at which UTC+03 with no DST is applied is actually the easternmost point of Saudi Arabia, in the Eastern Province, at the border with Oman, with a longitude of roughly 55°20' E.
Also Africa population is huge yet they have so little vegetation

Eastern European Summer Time - Territories observing European Union DST rules
- Cyprus (including Akrotiri and Dhekelia (UK) and Turkish Republic of Northern Cyprus)
- Finland (including Åland)
Middle East - observing various DST rules
- The westernmost point at which UTC+03 with DST is applied is actually 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 actually 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.
