Why people convert MDT to Shanghai time
- Scheduling a call from MDT to Shanghai: a 10:00 AM start in MDT lands at 12:00 AM in Shanghai the next day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +14h gap: MDT and Shanghai 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 Shanghai is 11:00 PM in MDT.
- Keeping family and friends in sync: knowing that 8:00 PM in MDT is 10:00 AM in Shanghai 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 +14h gap is not.
- With a +14h gap there is no shared 9-to-5 window, so alternate the early start: one week MDT takes the early slot, the next week Shanghai does.
