Moscow Time

Moscow Time (MSK, Russian: моско́вское вре́мя, romanized: moskovskoye vremya) is the time zone for the city of Moscow, Russia, and most of western Russia, including Saint Petersburg.

Other zones east of the 37.5° meridian to Arkhangelsk, Vologda, Yaroslavl, Kostroma, Ivanovo, Vladimir, Ryazan, Tula, Lipetsk, Voronezh and Rostov-on-Don were also included in the second belt.

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.

Most of the European part of Russia (west of the Ural Mountains) uses Moscow Time.
