Which zone this page means. MST is standard time only; MDT (UTC-6) applies from March to November. Arizona stays on MST all year. IST means India Standard Time (UTC+5:30), Irish Standard Time (UTC+1) and Israel Standard Time (UTC+2). This page means the Indian zone, which is one of the few on a half-hour offset.
MST is behind IST by 11.5 hours today
On 28 August 2026, Mountain Standard Time is on MDT at
UTC-06:00 and India Standard Time is on IST at
UTC+05:30. The gap between them is 11.5 hours, with IST ahead. So 9:00 am in MST is
8:00 pm in IST, and 5:00 pm in MST is
4:00 am in IST. Going the other way, see IST to MST.
The gap is not constant, and that is the part that catches people out
Mountain Standard Time is currently observing daylight saving and changes next on 1 November 2026, when clocks go back an hour. India Standard Time does not observe daylight saving at all, so the whole of the seasonal change comes
from the MST side: the gap moves by an hour twice a year even though nothing changes in
India Standard Time.
When you can actually both be at work
Taking a working day as 9:00 am to 5:00 pm local at each end, there
are0 overlapping hours
in a normal day. There is none: the two working days do not touch at all, so any live meeting between Mountain Standard Time and India Standard Time has to sit outside somebody's normal hours. The table above shows which end has the shorter stretch to give up.
Zone rules are set by legislation and change, sometimes at short notice. This page is
built against tzdata 2026a, last reviewed
2026-08-18. Quarterly. Zone rules change by legislation, sometimes at short notice. Version and review date are shown on every zone page. The converter above reads
your browser's own copy of the zone database, so if a rule has changed since this page was built the
live answer follows the new rule — and so does everything above, which is worked out from the same
database when you open the page.
Every convention used above — whether the start date counts, how month ends are
clamped, which holidays close an office — is written out on the
methodology page, including the daylight-saving rules behind the 11.5-hour gap above.
The current offset is shown at the top of this page. It is computed for today's date rather than quoted as an average, because the two regions change their clocks on different dates and the gap is different for a few weeks each year.
Is MST the same as Mountain Standard Time all year?
Not necessarily. Standard time and summer time are separate zones with separate abbreviations, so much of the year the technically correct abbreviation is the daylight one. The page states which is in force on today's date.
When do the clocks change in these zones?
The next change date for each zone is shown in the result panel, along with what the offset becomes afterwards.
What is a good meeting time between MST and IST?
The business-hours overlap window is shown below the converter. Where there is no overlap the page says so rather than suggesting an impossible time.
