Convert a specific time from MSK to MST
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.
What is the time difference between MSK and MST?
Mountain Time is 9 hours behind Moscow Time. To go from MSK to MST you subtract 9 hours. That gap is not fixed. Across 2026 the distance between these two zones takes 2 different values, from 9 hours to 10 hours, because Mountain moves its clocks and Moscow does not. This page recomputes it rather than assuming.

What are the best hours to schedule a call between MSK and MST?
No hour of the standard 9:00 am to 5:00 pm working day falls inside working hours on both sides. Moscow and Mountain 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.
| MSK | MST | Working hours | Note |
|---|---|---|---|
| 4:00 pm | 7:00 am | MSK only | afternoon in Moscow, early morning in Mountain |
| 5:00 pm | 8:00 am | neither side | evening in Moscow, mid morning in Mountain |
| 6:00 pm | 9:00 am | MST only | evening in Moscow, mid morning in Mountain |
Does daylight saving change MSK to MST?
Moscow Time does not move its clocks at all, so its UTC+3 offset holds every day of the year.
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.
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 MSK ahead of or behind MST?
MSK is ahead of MST by 9 hours: when it is 12:00 pm in Moscow, it is 3:00 am in Mountain. 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 "msk to mst" they nearly always mean the zone rather than the literal winter offset, so this page resolves MSK to Europe/Moscow and MST to America/Denver and applies whichever offset is genuinely in force on the day.
Moscow Time covers Moscow and western Russia, fixed since 2014. Mountain Time covers Denver, Salt Lake City, Albuquerque and Calgary. The identifiers behind them are Europe/Moscow and America/Denver, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
