Why people convert Moscow to MDT time
- Scheduling a call from Moscow to MDT: a 10:00 AM start in Moscow lands at 1:00 AM in MDT, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -9h gap: Moscow and MDT have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in MDT is 12:00 AM in Moscow.
- Watching a live event or market open: Moscow viewers need 12:00 AM in MDT to catch a 9:00 AM start there, and 9:00 AM if the event is anchored to Moscow.
- Always state the zone abbreviation, not just the hour. "3:00 PM MSK" is unambiguous; "3 PM" across a -9h gap is not.
- With a -9h gap there is no shared 9-to-5 window, so alternate the early start: one week Moscow takes the early slot, the next week MDT does.
