There are 11 time zones in Russia, which currently observe times ranging from UTC+02:00 to UTC+12:00. Daylight saving time (DST) has not been used in Russia since 26 October 2014. From 27 March 2011 to 26 October 2014, permanent DST was used.
Prior to 2011, Russia moved its clocks backward and forward on the same annual cycle as Europe. On 27 March 2011, clocks were advanced as usual, but they did not go back on 30 October 2011, effectively making Moscow Time UTC+04:00 permanently.[5] On 26 October 2014, following another change in the law, the clocks in most of the country were moved back one hour, but summer daylight saving time was not reintroduced; Moscow Time returned to UTC+03:00 permanently.[6]
History
Russian Empire
In the Russian Empire, most of the nation observed solar time. Until Saturday, 7 October [19 October, N.S.] 1867 at 3:30p.m. GMT+14:59 in the capital of New Archangel (Sitka) (00:31 GMT), Alaska belonged to Russia (Russian America) which used the Julian calendar, which was 11 or 12 days behind the Gregorian calendar (as used by the rest of Russia) and had local times up to GMT+15:10. The westernmost area of Russia was Congress Poland, with local times down to GMT+01:10.
During the late 19th century, Moscow Mean Time was introduced on 1 January [13 January, N.S.] 1880, originally at GMT+02:30:17.[7] 2:30:17 corresponds to 37.6166667°, the longitude of Moscow. Other parts of Russia kept solar time for several years.
Russia adopted the Gregorian calendar in 1918, when Wednesday 31 January (O.S.) was followed by Thursday 14 February (N.S.), which dropped 13 days from the calendar.
Soviet Union
After the Soviet Union was created, Moscow Time became UTC+02:00 and the various other time zones (up to UTC+12:00) were introduced throughout Russia and the rest of the Soviet Union, for example Irkutsk Time UTC+07:00 (Irkutsk has since this always been MSK+5).[7] Between 1917 and 1922 the time was less ordered, with daylight saving time some of those years, some with two hours addition, and some of those years with one or two hours extra winter time.[7]
On 21 June 1930, the Soviet Union advanced all clocks by one hour, effectively making the nation run on daylight saving time all year (the so-called decree time).
On 1 April 1981, 00:00:00, Oymyakonsky District changed its time zone from MSK+6 to MSK+8.[8] The change occurred during DST effectively changing the offset from UTC+09:00 to UTC+12:00, the offset without DST was therefore changed from UTC+09:00 to UTC+11:00. [citation needed]
On 1 April 1982, 00:00:00, Chukotka Autonomous Okrug changed its time zone from MSK+10 to MSK+9, thus eliminating Anadyr Time (MSK+10 or UTC+13:00 without DST).[9] The change occurred during DST effectively changing the offset from UTC+14:00 to UTC+13:00, the offset without DST was therefore changed from UTC+13:00 to UTC+12:00.
On 27 March 1988, 02:00:00, Saratov and Volgograd oblasts changed its time zone from MSK+1 to MSK.[10][11] The change occurred during DST effectively changing the offset from UTC+05:00 to UTC+04:00, the offset without DST was therefore changed from UTC+04:00 to UTC+03:00.
On 26 March 1989, Kaliningrad Oblast switched from Moscow Time to Eastern European Time, and the following areas switched to Moscow Time (thus eliminating Samara Time; MSK+1 or UTC+04:00 without DST):
Russia and most republics in the Soviet Union abolished the decree time (not moving the clocks) on 31 March 1991, but Russia reversed this the following year (except Samara Oblast which was already in UTC+04:00).[citation needed]
On 20 October 1991, Samara Oblast changed its time zone from MSK to MSK+1 (thus reinstating Samara Time; MSK+1), so from UTC+03:00 to UTC+04:00.[12]
On 23 May 1993, Novosibirsk Oblast changed its time zone from MSK+4 to MSK+3.[13] The change occurred during DST effectively changing the offset from UTC+08:00 to UTC+07:00, the offset without DST was therefore changed from UTC+07:00 to UTC+06:00.
Although the Russian government wanted to reduce the number of time zones even further, there were protests in far-eastern Russia on the changes, including a 20,000-strong petition in support of Kamchatka returning to UTC+12:00.[21]
Decree No.725 of 31 August 2011 changed the UTC offset for Moscow Time and the other time zones.[22]Moscow Time Zone began using UTC+04:00 all year around. The notions of decree time and daylight saving time were abolished, but in fact, this decree mandated permanent daylight saving time (or even double daylight saving time in regions that had not abolished the decree time).
The decree also changed the offset of some parts of the Sakha Republic from Moscow. Oymyakonsky District switched from Magadan Time (MSK+8) to Vladivostok Time (MSK+7), and the following areas switched from Vladivostok Time (MSK+7) to Yakutsk Time (MSK+6):
In July 2014, further changes were passed, which took effect on 26 October 2014. Almost all of Russia moved back one hour, so Moscow Time became UTC+03:00 again. Some areas changed offset from Moscow:[24]
The parts of the Magadan Time zone that remained on MSK+8 were given a new time zone name, Srednekolymsk Time, UTC+11:00. Annual DST changes were not observed.[25]
The following time zone changes occurred on 27 March 2016:[26]
Astrakhan and Ulyanovsk oblasts moved forward one hour from UTC+03:00 to UTC+04:00 (from Moscow to Samara time)
Altai Krai and Altai Republic moved forward one hour from UTC+06:00 to UTC+07:00 (from Omsk to Krasnoyarsk time)
Zabaykalsky Krai moved forward one hour from UTC+08:00 to UTC+09:00 (from Irkutsk to Yakutsk time)
Sakhalin Oblast moved forward one hour from UTC+10:00 to UTC+11:00 (from Vladivostok to Srednekolymsk time), except Severo-Kurilsky District, which was already in UTC+11:00 (Srednekolymsk Time)
On 24 April 2016, Magadan Oblast moved forward one hour from UTC+10:00 to UTC+11:00 (from Vladivostok to Srednekolymsk time).[27] After this change, the UTC+11:00 time zone was again called Magadan Time.[28]
On 29 May 2016, Tomsk Oblast moved forward one hour from UTC+06:00 to UTC+07:00 (from Omsk to Krasnoyarsk time).[29]
On 24 July 2016, Novosibirsk Oblast moved forward one hour from UTC+06:00 to UTC+07:00 (from Omsk to Krasnoyarsk time).[30]
On 4 December 2016, Saratov Oblast moved forward one hour from UTC+03:00 to UTC+04:00 (from Moscow to Samara time).[31][32]
On 28 October 2018, Volgograd Oblast moved forward one hour from UTC+03:00 to UTC+04:00 (from Moscow to Samara time),[33] but this change was reverted on 27 December 2020.[34][35]
After the Russian annexation of Donetsk, Kherson, Luhansk and Zaporizhzhia oblasts in September 2022, the parts of these oblasts under Russian administration remained on Moscow Time (UTC+03:00) and did not revert to UTC+02:00 with the rest of Ukraine at the end of its daylight saving time period in October 2022.[36] In April 2023, the Russian time zone law was changed to formally include these oblasts in Moscow Time.[37]
Railway time
Until 2018, all timetables on Russian Railways (except Sakhalin railways) followed Moscow Time. From 2018 time tables follow local time.[38][39] Airports and flights follow local time.[40]
The list below shows the 16 zones for Russia as defined in the file zone.tab of the database. The database aims to identify regions that had the same time offset rules since 1970.
On the last Sunday in October 2011, daylight-saving time ended in tzdata, but all zones moved forward one hour. In other words, the clocks did not change, but the names of the time zones reverted permanently to their standard time variants and there will be no more daylight-saving time. [citation needed]
If available, the change column lists the offset changes that caused a creation of a new zone in the tz database.
"Initial zone" means that in 1970 there was already a difference in time offset from the offsets in any other zone.
Asia/Ulan Ude was a time zone identifier from the zone file of the tz database. The reference point was Ulan-Ude. It was added in tz version 2011e.[43] Edition 2011i did not contain it anymore. The area remained at Asia/Irkutsk. The contained data in zone.tab was:
Central European Time (CET) is a standard time of Central, and parts of Western Europe, which is one hour ahead of Coordinated Universal Time (UTC). The time offset from UTC can be written as UTC+01:00. It is used in most parts of Europe and in a few North African countries. CET is also known as Middle European Time and by colloquial names such as Amsterdam Time, Berlin Time, Brussels Time, Budapest Time, Madrid Time, Paris Time, Rome Time, Prague time, Warsaw Time or Romance Standard Time (RST).
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.
Moscow Time is the time zone for the city of Moscow, Russia, and most of western Russia, including Saint Petersburg. It is the second-westernmost of the eleven time zones of Russia. It has been set to UTC+03:00 without DST since 26 October 2014; before that date it had been set to UTC+04:00 year-round on 27 March 2011.
UTC+11:00 is an identifier for a time offset from UTC of +11:00. This time is used in:
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 ahead of 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.
UTC+04:00 is an identifier for a time offset from UTC of +04:00. In ISO 8601, the associated time would be written as 2019-02-07T23:28:34+04:00. This time is used in:
Omsk Time (OMST) is a time zone in Russia that is six hours ahead of UTC (UTC+06:00), and 3 hours ahead of Moscow Time (MSK). It is used in Omsk Oblast.
Yekaterinburg Time (YEKT) is the time zone five hours ahead of UTC (UTC+05:00) and 2 hours ahead of Moscow Time (MSK+2).
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.
Bangladesh Standard Time serves as the official time zone for Bangladesh. It operates six hours ahead of Coordinated Universal Time and is observed uniformly across the country as a national standard. In 2009, Bangladesh briefly observed daylight saving time (DST) as a measure to address an ongoing electricity crisis. However, this decision was reversed by the government in 2010.
Magadan Time (MAGT) is a time zone in Russia, named after Magadan, the administrative center of Magadan Oblast. It is 11 hours ahead of UTC (UTC+11) and 8 hours ahead of Moscow Time (MSK+8).
Samara Time (SAMT) is the time zone four hours ahead of UTC (UTC+4) and 1 hour ahead of Moscow Time (MSK+1). Samara Time is used in Astrakhan Oblast, Samara Oblast, Saratov Oblast, Udmurtia, and Ulyanovsk Oblast.
Irkutsk Time (IRKT) is the time zone eight hours ahead of UTC (UTC+08:00) and 5 hours ahead of Moscow Time (MSK+5).
Vladivostok Time (VLAT), is a time zone in Russia, named after the city of Vladivostok. It is ten hours ahead of UTC (UTC+10:00) and seven hours ahead of Moscow Time (MSK+7).
Kamchatka Time or Petropavlovsk Time (PETT; Russian: камчатское время, kamchatskoye vremya), also known as Anadyr Time (ANAT), is a time zone in Russia, named after the Kamchatka Peninsula. It is 12 hours ahead of UTC (UTC+12:00) and 9 hours ahead of Moscow Time (MSK+9). This time zone is used in the two easternmost regions of Russia after October 2014 and was also used before the time zone reform of 2010.
As of 2022, daylight saving time is used in the following Asian countries:
Daylight saving time (DST), also known as summer time, is the practice of advancing clocks during part of the year, typically by one hour around spring and summer, so that daylight ends at a later time of the day. As of 2024, DST is observed in most of Europe, most of North America and parts of Africa and Asia around the Northern Hemisphere summer, and in parts of South America and Oceania around the Southern Hemisphere summer. It was also formerly observed in other areas.
The Republic of Sakha is the only federal subject of Russia which uses more than one time zone. Sakha spans three time zones.
