Timezone conversion
MST to IST Time — Convert Mountain Standard Time (US) to India Standard Time
IST is currently 11 hours and 30 minutes ahead of MST. The gap shifts across the year: around January IST is 12 hours and 30 minutes ahead of MST, and around July it is 11 hours and 30 minutes ahead of MST, because one or both zones observe daylight saving.
IST is currently 11 hours and 30 minutes ahead of MST.
Abbreviation disambiguation
MST is Mountain Standard Time (UTC−7). Most of the US Mountain zone switches to MDT (UTC−6) in summer, but Arizona (except the Navajo Nation) stays on MST year-round.
On Clockjumper, IST refers to India Standard Time (UTC+5:30). The same three letters are also used for Israel Standard Time (UTC+2) and Irish Standard Time (UTC+1) — check the city or UTC offset to be sure which is meant.
