IST to MDT time conversion
The difference between IST and MDT is fixed: MDT is 11 hours 30 minutes behind IST. For example, 9:00 AM (09:00) IST is 21:30 MDT, and 6:00 PM (18:00) IST is 06:30 MDT. The chart above lists the conversion for every hour of the day.
These conversions use each zone's standard UTC offset — UTC+05:30 for IST (India Standard Time) and UTC−06:00 for MDT (Mountain Daylight Time) — so the result is exact and does not shift with Daylight Saving Time. To convert a real calendar date between cities with automatic DST handling, use the full time zone converter.
