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. Moscow Time has been UTC+4 year-round since 27 March 2011,[1] but will change to UTC+3 permanently on 25 October 2014.[2]

Moscow Time is used to schedule trains, ships, etc. throughout the Russian Federation, 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+10) is said to be MSK+6 within Russia.


In accordance with the 16 June 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 3 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.[2] On 27 March 2011, Muscovites set their clocks forward for a final time, effectively observing MSD, or UTC+4, permanently.

On March 29, 2014, after the accession of Crimea to the Russian Federation the Republic of Crimea and the city of Sevastopol 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 except Perm Krai, Bashkortostan and Orenburg Oblast) uses Moscow Time. In Kaliningrad Oblast, UTC+3 is used.

Past usage[edit]

Prior to 27 March 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 1922–30 and 1991–92, 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.
