IST to MST Converter
Convert India Standard Time to Mountain Time
Convert India Standard Time (IST) to Mountain Time (MST) in one place. This free converter shows the current time in both zones, lets you turn any IST time into the matching MST time, and includes a full conversion table for the day. Right now MST is 11 hours and 30 minutes behind IST. Mountain Time switches between Mountain Standard Time (MST) and Mountain Daylight Time (MDT) across daylight saving.
Because it reads live time zone rules, the offset stays correct through daylight saving changes on either side, so you never have to work the difference out by hand. It is handy for scheduling calls and meetings, catching a live stream or match, or keeping in touch with family and colleagues across the two regions.
