Why people convert MDT to Bangkok time
- Scheduling a call from MDT to Bangkok: a 10:00 AM start in MDT lands at 11:00 PM in Bangkok, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +13h gap: MDT and Bangkok 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 Bangkok is 10:00 PM in MDT.
- Watching a live event or market open: MDT viewers need 10:00 PM in Bangkok to catch a 9:00 AM start there, and 11:00 AM if the event is anchored to MDT.
- Always state the zone abbreviation, not just the hour. "3:00 PM MDT" is unambiguous; "3 PM" across a +13h gap is not.
- With a +13h gap there is no shared 9-to-5 window, so alternate the early start: one week MDT takes the early slot, the next week Bangkok does.
