Adoption History & Astronomical Facts
Year Established: 1919
Adopted in 1919 by the Council of People's Commissars. In 2011, President Dmitry Medvedev abolished seasonal clock changes and locked Russia on permanent summer time (UTC+4). Following years of complaints from parents and doctors regarding winter morning darkness, President Vladimir Putin signed Federal Law No. 248-FZ in 2014, moving the country permanently back to winter standard time (UTC+3).
Until August 2018, every railway departure board and train ticket across Russia—from Saint Petersburg on the Baltic Sea all the way to Vladivostok on the Pacific coast—was printed strictly in Moscow Time, forcing travelers in Siberia to constantly convert between their local time and the Moscow timetable.
