Daylight saving time in Russia was originally introduced on 30 June [13 July, N.S.] 1917 by a decree of the Russian Provisional Government. However, it was abandoned by a Decree of the Soviet government five months later.
Daylight saving time was re-introduced in the USSR on 1 April 1981, by a decision of the Council of Ministers of the USSR. Daylight saving time began on 1 April and ended on 1 October each year, until mid-1984, when the USSR began following European daylight saving time rules, moving clocks forward one hour at 02:00 local standard time on the last Sunday in March, and back one hour at 03:00 local daylight time on the last Sunday in September until 1995, after which the change back occurred on the last Sunday in October. The usage of daylight saving time continued after the Soviet collapse but ended in 2011, when Russia stopped observing daylight saving time.
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. 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 Time was not reintroduced; Moscow Time returned to UTC+03:00 permanently. Since this reform, most Russian territories have a standard time ahead of mean solar time, including some cities which are ahead by a whole hour. For example, St. Petersburg at 30°E [+2h (*solar time)] has UTC+03:00, Yekaterinburg at 60°E (+4h*) has UTC+05:00, and Vladivostok at 132°E (+9h*) has UTC+10:00.
In the Russian Empire, most of the nation observed solar time. During the late 19th century, Moscow Mean Time was introduced on 1 January [13 January, N.S.] 1880, originally at GMT+02:30:17. 2:30:17 corresponds to 37.6166667°, the longitude of Moscow. Other parts of Russia kept solar time for several years. At this time, Russia had the Julian calendar with 12 or 13 days less date compared to Western Europe, so it is possible to say the Moscow actually had GMT-285:29:43 (GMT-11d 21h 29m 43s) (29 February [12 March, N.S.] 1800 − 28 February [12 March, N.S.] 1900), GMT-309:29:43 (GMT-12d 21h 29m 43s) (29 February [13 March, N.S.] 1900 − 3 July [16 July, N.S.] 1916) and GMT-309:28:41 (GMT-12d 21h 28m 41s) (3 July [16 July, N.S.] 1916 − 31 January [13 February, N.S.] 1918). Russia adopted the Gregorian calendar on Thursday, 14 February 1918, which most of Europe already used.
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). Between 1917-1922 the time was less ordered, with daylight savings time some of those years, some with two hours addition, and some of those years with one or two hours extra winter time.
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, daylight saving time (two hours ahead of standard time) was re-introduced; clocks were moved one hour forward on 1 April (the last Sunday of March since 1985) and one hour back on 1 October (the last Sunday of September since 1984, the last Sunday of October since 1996).
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.
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.
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, the following changes were introduced, which, in particular, some oblasts switched to Moscow Time (thus eliminating Samara Time; MSK+1 or UTC+4 without DST):
Some oblasts switched from Moscow Time to Eastern European Time:
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).
On 29 September 1991, 03:00:00, Samara Oblast changed its time zone from MSK to MSK+1 (thus reinstating Samara Time; MSK+1). So the zone boundaries on 20 October, Samara Oblast changed its time zone from UTC+03:00 to UTC+04:00.
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.
The following time zone changes occurred on 28 March 2010, which, in particular, led to abolition of two of the eleven time zones.
Although the Russian government wants to reduce the number of time zones even further, there have been protests in far-eastern Russia on the recent changes, including protests and a 20,000-strong petition in support of Kamchatka returning to UTC+12:00.
The decree No. 725 (31 August 2011) changed UTC offset for Moscow Time and the other time zones. Moscow Time Zone now used UTC+04:00 all year around. The notions of decree time and daylight saving time were abolished in the law, but in fact, this law mandated permanent daylight saving time (or even double daylight saving time in regions that had not abolished the decree time). Some areas changed offset from Moscow:
Some districts of the Sakha Republic switched from Magadan Time (Zone 9) to Vladivostok Time (from Zone 8):
Some districts of the Sakha Republic switched from Vladivostok Time (Zone 8) to Yakutsk Time (Zone 7):
As a result of the annexation of Crimea by the Russian Federation, local authorities in the Republic of Crimea and Sevastopol decreed that clocks in the newly proclaimed Russian federal subjects should jump ahead two hours at 10 p.m. on 29 March 2014 to switch from Eastern European Time (UTC+02:00) to Moscow Time (UTC+04:00).
Annual DST changes is not observed.
The following time zone changes occurred on 27 March 2016:
The following time zone change occurred on 24 April 2016:
After these changes, the UTC+11:00 time zone is also named Magadan Time, Srednekolymsk Time or Sakhalin Time.
The following time zone change occurred on 29 May 2016:
The following time zone change occurred on 24 July 2016:
The following time zone change occurred on 28 October 2018:
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.
Two federal subjects are contained in more than one tz zone. The Sakha Republic is divided into three: west, central, east. Sakhalin Oblast is divided into two: Sakhalin Island with Kurilsky and Yuzhno-Kurilsky districts in the Kuril Islands, and Severo-Kurilsky District in the Kuril Islands.
Two zones, namely Asia/Omsk and Asia/Novosibirsk, each cover area that did not observe the same rule set since 1970, all now using Omsk Time.
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.
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. Edition 2011i did not contain it anymore. The area remained at Asia/Irkutsk. The contained data in zone.tab was:
RU +5150+10736 Asia/Ulan_Ude Moscow+05 - Buryatia
The covered area was Republic of Buryatia.
Central European Summer Time (CEST), sometime referred also as Central European Daylight Time (CEDT), is the standard clock time observed during the period of summer daylight-saving in those European countries which observe Central European Time (UTC+1) during the other part of the year. It corresponds to UTC+2, which makes it the same as Central Africa Time, South African Standard Time and Kaliningrad Time in Russia.Irkutsk Time
Irkutsk Time (IRKT) is the time zone eight hours ahead of UTC (UTC+08:00) and 5 hours ahead of Moscow Time (MSK+5).
The time zone covers Buryatia and Irkutsk Oblast.
On 27 March 2011, Russia moved to year-round daylight saving time. Instead of switching between UTC+08:00 in winter and UTC+09:00 in summer, Irkutsk Time became fixed at UTC+09:00 until 2014, when it was reset back to UTC+08:00 year-round.Kaliningrad Time
Kaliningrad Time is the time zone two hours ahead of UTC (UTC+02:00) and 1 hour behind Moscow Time (MSK−1). It is used in Kaliningrad Oblast.
Until 2011, Kaliningrad Time was identical to Eastern European Time (UTC+02:00; UTC+03:00 with daylight saving time). On 27 March 2011, Russia moved to permanent DST, so that clocks would remain on what had been the summer time all year round, making Kaliningrad time permanently set to UTC+03:00. On 26 October 2014, this law was reversed, but daylight saving time was not reintroduced, so Kaliningrad is now permanently set to UTC+02:00.Main cities:
Kamchatka 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.
Kamchatka Summer Time (PETST) corresponded to UTC+13:00, but still 9 hours ahead of Moscow (MSD+9). This no longer exists, effective in the 2014 change.
On March 28, 2010, while most regions of Russia switched to Summer Time moving the clocks one hour forward, the two Russian regions using Kamchatka Time, Kamchatka Krai and Chukotka Autonomous Okrug, retained UTC+12:00, effectively joining Magadan Summer Time. This change was reversed on 26 October 2014.Krasnoyarsk Time
Krasnoyarsk Time (KRAT) is the time zone seven hours ahead of UTC (UTC+07:00) and 4 hours ahead of Moscow Time (MSK+4). KRAT is the official time zone for central and east Siberian regions of Krasnoyarsk Krai, Kemerovo Oblast, Khakassia and Tuva.
Novosibirsk Oblast used this time zone until 1993 when it was known as Novosibirsk Time NOVT/NOVST. It was renamed after that.
Between 27 March 2011 and 25 October 2014, Krasnoyarsk Time was fixed at UTC+08:00.In 2016, the Altai Republic, Altai Krai, Novosibirsk Oblast, and Tomsk Oblast, switched to Krasnoyarsk Time from Omsk Time.Moscow Time
Moscow Time (Russian: моско́вское вре́мя) 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 permanently on 26 October 2014; before that date it had been set to UTC+04:00 year-round since 27 March 2011.Moscow Time is used to schedule trains, ships, etc. throughout Russia, but airplane travel is scheduled using local time. Trains are going to follow local time by 1 August. Times in Russia are often announced throughout the country on radio stations as Moscow Time, which is also registered in telegrams, etc. Descriptions of time zones in Russia are often based on Moscow Time rather than UTC. For example, Yakutsk (UTC+09:00) is said to be MSK+6 in Russia.Omsk Time
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).RBU (radio station)
RBU is a time code radio station located in Moscow (56°44′00″N 37°39′48″E). It transmits a continuous 10 kW time code on 66⅔ kHz. This is commonly written as 66.66 or 66.666 kHz, but is actually 200/3 = 66.6̅ kHz. Until 2008, the transmitter site was near Kupavna 55°44′04″N 38°9′0″E and used as antenna three T-antennas spun between three 150 metres tall grounded masts. In 2008, it has been transferred to the Taldom transmitter at 56°44′00″N 37°39′48″E.
RBU is controlled by All-Russian Scientific Research Institute for Physical-Engineering and Radiotechnical Metrology. It is operated by Russian Television and Radio Broadcasting Network.Samara Time
Samara Time (SAMT) is the time zone 4 hours ahead of UTC (UTC+04:00) and 1 hour ahead of Moscow Time (MSK+1). Samara Time is used in Samara Oblast, Udmurtia, Astrakhan Oblast, Ulyanovsk Oblast, Saratov Oblast, and Volgograd Oblast.Vladivostok Time
Vladivostok Time (VLAT) (Russian: владивостокское время, vladivostokskoye vremya), 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).
On 27 March 2011, Russia moved to year-round daylight saving time. Instead of switching between UTC+10:00 in winter and UTC+11:00 in summer, Vladivostok Time became fixed at UTC+11:00 until 2014, when it was reset back to UTC+10:00 year-round.Yakutsk Time
Yakutsk Time (YAKT) is a time zone in Russia which is nine hours ahead of UTC, and six hours ahead of Moscow Time (MSK).The time zone covers Sakha Republic (western part), Amur Oblast and Zabaykalsky Krai.On 27 March 2011, Russia moved to year-round daylight saving time. Instead of switching between UTC+09:00 in winter and UTC+10:00 in summer, Yakutsk Time became fixed at UTC+10:00 until 2014, when it was reset back to UTC+09:00 year-round.Yekaterinburg Time
Yekaterinburg Time (YEKT) is the time zone five hours ahead of UTC (UTC+05:00) and 2 hours ahead of Moscow Time (MSK+2).
In 2011, Russia moved to year-round daylight saving time. Instead of switching between UTC+05:00 in winter and UTC+06:00 in summer, Yekaterinburg time was set to UTC+06:00 until 2014, when it was reset back to UTC+05:00 year-round.The time zone applies to the Ural Federal District, and Bashkortostan, Orenburg Oblast and Perm Krai in the Volga Federal District.
