Why people convert MDT to Moscow time
- Scheduling a call from MDT to Moscow: a 10:00 AM start in MDT lands at 7:00 PM in Moscow, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +9h gap: MDT and Moscow 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 Moscow is 6:00 PM in MDT.
- Keeping family and friends in sync: knowing that 8:00 PM in MDT is 5:00 AM in Moscow makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM MDT" 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 MDT takes the early slot, the next week Moscow does.
