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 11 time zones of Russia.
During the winter, between the last Sunday of October and the last Sunday of March, Moscow Standard Time (MSK, МСК) is 3 hours ahead of UTC, or UTC+3. During the summer, Moscow Time shifts forward an additional hour ahead of Moscow Standard Time to become Moscow Summer Time (MSD), making it UTC+4.
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.
Moscow Time is in use for scheduling trains, airplanes, ships, etc. throughout the Russian Federation, this time is registered in telegrams, etc. Times in Russia are often announced throughout the country on radio stations as Moscow Time.
