Why people convert China to MDT time
- Scheduling a call from China to MDT: a 10:00 AM start in China lands at 8:00 PM in MDT the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -14h gap: China 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 7:00 PM in China.
- Watching a live event or market open: China viewers need 7:00 PM in MDT to catch a 9:00 AM start there, and 2:00 PM if the event is anchored to China.
- Always state the zone abbreviation, not just the hour. "3:00 PM CST" is unambiguous; "3 PM" across a -14h gap is not.
- With a -14h gap there is no shared 9-to-5 window, so alternate the early start: one week China takes the early slot, the next week MDT does.
