Moscow Time

For the newspaper, see The Moscow Times.

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 nine time zones of Russia. It has been set to UTC+3 permanently on October 26, 2014;[1] before that date it had been set to UTC+4 year-round since March 27, 2011.[2]

Moscow Time is used to schedule trains, ships, etc. throughout Russia, while airplane travel is scheduled using local time. Times in Russia are often announced throughout the country on radio stations as Moscow Time, and this time 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+9) is said to be MSK+6 within Russia.


In accordance with the June 16, 1930 Decree of the Council of People's Commissars, the Decree Time was introduced by adding one hour to the time in each time zone of the USSR, so that Moscow Time became three hours ahead of Coordinated Universal Time.[citation needed]

Until 2011, during the winter, between the last Sunday of October and the last Sunday of March, Moscow Standard Time (MSK, МСК) was three hours ahead of UTC, or UTC+3; during the summer, Moscow Time shifted forward an additional hour ahead of Moscow Standard Time to become Moscow Summer Time (MSD), making it UTC+4.

In 2011, the Russian government proclaimed that daylight saving time would in future be observed all year round, thus effectively displacing standard time—an action which the government claimed emerged from health concerns attributed to the annual shift back-and-forth between standard time and daylight saving time.[1] On March 27, 2011, Muscovites set their clocks forward for a final time, effectively observing MSD, or UTC+4, permanently.

On March 29, 2014, after the annexation of Crimea by the Russian Federation, the Republic of Crimea and the city of Sevastopol—two federal subjects established by Russia on the Crimean Peninsula—switched their time to MSK.

In July 2014, the State Duma passed a bill repealing the 2011 change, putting Moscow Time on permanent UTC+3.


Most of the European Russia (the portion of Russia west of the Ural Mountains) uses Moscow Time. In Kaliningrad Oblast, Kaliningrad time (UTC+2) is used. Samara Oblast and Udmurtia use Samara time (UTC+4) and Perm Krai, Bashkortostan and Orenburg Oblast use Yekaterinburg time (UTC+5).

Past usage

Prior to March 27, 2011, Moscow Time was UTC+3. Daylight saving time was used in the summer, advancing it to UTC+4.

UTC+3 was also formerly used in European parts of what was then the USSR:

Moscow Summer Time (UTC+4), was first applied in 1981 and was used:

In 1922–1930 and 1991–1992, Moscow observed EET (UTC+2). Daylight saving time (UTC+3) was observed in the summer of 1991, and the city and region reverted to UTC+3 by the summer of 1992.

The time in Moscow has been as follows (the list of DST usage is probably not accurate here):[3]

From 1880 UTC+2:30
From July 1919 UTC+3
From October 1922 UTC+2 (EET)
From June 21, 1930 UTC+3
From April 1, 1981 UTC+3 with DST
From March 31, 1991 UTC+2 with DST
From Jan 19, 1992 UTC+3 with DST
From March 27, 2011 UTC+4
From October 26, 2014 UTC+3
