Best time to meet between IST and MST
There is no overlap between 9 AM and 6 PM in both places.
If both sides can be flexible (7 AM – 10 PM):
- 7:00 AM – 10:00 AM IST = 7:30 PM – 10:30 PM MST
- 7:00 PM – 10:00 PM IST = 7:30 AM – 10:30 AM MST
The time difference changes during the year because of daylight saving time, so these windows shift by an hour at other times.
