Why people convert MDT to India time
- Scheduling a call from MDT to India: a 10:00 AM start in MDT lands at 9:30 PM in India, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +11h 30m gap: MDT and India 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 India is 8:30 PM in MDT.
- Watching a live event or market open: MDT viewers need 8:30 PM in India to catch a 9:00 AM start there, and 12:30 PM 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 +11h 30m gap is not.
- With a +11h 30m gap there is no shared 9-to-5 window, so alternate the early start: one week MDT takes the early slot, the next week India does.
