Why people convert COT to MSK time
- Scheduling a call from COT to MSK: a 10:00 AM start in COT lands at 6:00 PM in MSK, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +8h gap: COT and MSK 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 MSK is 5:00 PM in COT.
- Watching a live event or market open: COT viewers need 5:00 PM in MSK to catch a 9:00 AM start there, and 4:00 PM if the event is anchored to COT.
- Always state the zone abbreviation, not just the hour. "3:00 PM COT" is unambiguous; "3 PM" across a +8h gap is not.
- With a +8h gap there is no shared 9-to-5 window, so alternate the early start: one week COT takes the early slot, the next week MSK does.
