Convert a specific time from MST to EET
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 MST and EET?
Eastern European Time is 9 hours ahead of Mountain Time. To go from MST to EET you add 9 hours. That gap is not fixed. Across 2026 the distance between these two zones takes 2 different values, from 8 hours to 9 hours, because the two sides change their clocks on different dates. This page recomputes it rather than assuming.

What are the best hours to schedule a call between MST and EET?
No hour of the standard 9:00 am to 5:00 pm working day falls inside working hours on both sides. Mountain and Eastern European 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 | EET | Working hours | Note |
|---|---|---|---|
| 7:00 am | 4:00 pm | EET only | early morning in Mountain, afternoon in Eastern European |
| 8:00 am | 5:00 pm | neither side | mid morning in Mountain, evening in Eastern European |
| 9:00 am | 6:00 pm | MST only | mid morning in Mountain, evening in Eastern European |
Does daylight saving change MST to EET?
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.
Eastern European Time is currently on EEST and changes next on Sunday, October 25, 2026, when the clock falls back from 3:59 am to 3:00 am and the offset moves from UTC+3 to UTC+2.
Because the two sides do not move together, the answer to this conversion changes during the year. The United States changes on the second Sunday in March and the first Sunday in November, while the United Kingdom and European Union change on the last Sunday in March and the last Sunday in October. Those dates are weeks apart, which opens a window each spring and autumn where the usual gap is an hour out. The table above is built for today, not for an average day.
Is MST ahead of or behind EET?
MST is behind EET by 9 hours: when it is 12:00 pm in Mountain, it is 9:00 pm in Eastern European. 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 eet" they nearly always mean the zone rather than the literal winter offset, so this page resolves MST to America/Denver and EET to Europe/Athens and applies whichever offset is genuinely in force on the day.
Mountain Time covers Denver, Salt Lake City, Albuquerque and Calgary. Eastern European Time covers Athens, Helsinki, Bucharest and Kyiv. The identifiers behind them are America/Denver and Europe/Athens, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
