Which zone this page means. 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. PST is standard time only. From the second Sunday in March to the first Sunday in November the Pacific zone is on PDT (UTC-7). Most people write PST year-round.
IST is ahead of PST by 12.5 hours today
On 28 August 2026, India Standard Time is on IST at
UTC+05:30 and Pacific Standard Time is on PDT at
UTC-07:00. The gap between them is 12.5 hours, with PST behind. So 9:00 am in IST is
8:00 pm in PST, and 5:00 pm in IST is
4:00 am in PST. Going the other way, see PST to IST.
The gap is not constant, and that is the part that catches people out
Pacific Standard Time is currently observing daylight saving and changes next on 1 November 2026. India Standard Time does not observe daylight saving, so the gap moves only when Pacific Standard Time changes
its clocks — twice a year, by one hour.
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 India Standard Time and Pacific 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 12.5-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 IST the same as India 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 IST and PST?
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.
