Convert a specific time from MST to MSK
Pick any time and date to convert it both ways. The conversion runs in your browser against the real zone rules, so a date inside a daylight saving period gets that period's offset rather than today's.

Moscow Time is 9 hours ahead of Mountain Time. To go from MST to MSK you add 9 hours. That gap is not fixed.

What are the best hours to schedule a call between MST and MSK?
No hour of the standard 9:00 am to 5:00 pm working day falls inside working hours on both sides. Mountain and Moscow are 9 hours apart, which is too far for an overlap, so somebody has to take a call outside their own working day. The least painful options are below, ranked by how close both sides sit to the middle of the afternoon.
| MST | MSK | Working hours | Note |
|---|---|---|---|
| 7:00 am | 4:00 pm | MSK only | early morning in Mountain, afternoon in Moscow |
| 8:00 am | 5:00 pm | neither side | mid morning in Mountain, evening in Moscow |
| 9:00 am | 6:00 pm | MST only | mid morning in Mountain, evening in Moscow |
Does daylight saving change MST to MSK?
Mountain Time is currently on MDT and changes next on Sunday, November 1, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC-6 to UTC-7.
Moscow Time does not move its clocks at all, so its UTC+3 offset holds every day of the year.
Because the two sides do not move together, the answer to this conversion changes during the year. For part of the year the gap is 9 hours and for the rest it is 10 hours. The table above is built for today, not for an average day.
Is MST ahead of or behind MSK?
MST is behind MSK by 9 hours: when it is 12:00 pm in Mountain, it is 9:00 pm in Moscow. One wrinkle worth knowing: MST and MDT are two names for the same zone, not two zones. Mountain Time reads MST in winter and MDT in summer. When somebody types "mst to msk" they nearly always mean the zone rather than the literal winter offset, so this page resolves MST to America/Denver and MSK to Europe/Moscow and applies whichever offset is genuinely in force on the day.
Mountain Time covers Denver, Salt Lake City, Albuquerque and Calgary. Moscow Time covers Moscow and western Russia, fixed since 2014. The identifiers behind them are America/Denver and Europe/Moscow, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
