About MST and IST
US Mountain Time (MST/MDT) is used in Denver and Salt Lake City. Clocks shift to MDT from March to November. Note that Arizona stays on MST all year.
India Standard Time (IST) is used across all of India, including Mumbai, Delhi, Bengaluru, Chennai and Kolkata. India does not observe daylight saving time.
Time difference between MST and IST
IST is 12 hours 30 minutes ahead of MST in winter (January) and 11 hours 30 minutes ahead of MST in summer (July), because of daylight saving changes. The clocks and table above are computed live from the official IANA time zone database in your browser, so daylight saving transitions are always already included.

Best hours for meetings
Scan the table for rows where both sides land inside working hours (9:00 to 18:00). Rows where one side is early morning or late evening are workable for a quick call; avoid rows where either side is in the middle of the night.
