CET vs. Moscow Time: No CET in Russia

Central European Time (CET, UTC+1) is not used in Russia. Russia spans 11 time zones (UTC+2 to UTC+12). Moscow Time (MSK) is UTC+3 year-round (since 2014, no DST).

Therefore, there is no CET/MSK difference because CET doesn't exist in Russia. In winter, CET (UTC+1) is 2 hours behind MSK (UTC+3). In summer, CEST (UTC+2) is 1 hour behind MSK. Always specify the Russian zone (e.g., MSK, YEKT, VLAT) when scheduling across regions.
