PST is 13 hours 30 minutes behind IST in winter and 12 hours 30 minutes behind, as PDT, in summer. IST is India Standard Time, UTC+5:30 all year. PST is US Pacific Time, PST at UTC−8 in winter and PDT at UTC−7 in summer. Paste a Unix timestamp, an ISO 8601 string or a plain date such as June 1 2026 3:00 pm and the converter shows that moment in both zones, with UTC and Unix time alongside.

Common questions
- What is the time difference between IST and PST?
- PST is 13 hours 30 minutes behind IST in winter and 12 hours 30 minutes behind, as PDT, in summer. The table on this page lists common IST hours with their PST equivalents, and the converter gives the exact gap for any date you enter.
- What time is it in PST right now?
- The PST panel at the top of the page shows the current local time there, next to IST, so you can compare at a glance. The offset line under it reports the gap for this moment, so you do not have to work out which side of a clock change you are on.
- How do I convert a specific IST time to PST?
- Type the IST time into the box and the panel shows the same moment in PST. For example, 09:00 in IST on 1 June 2026 is 20:30 the day before in PST. A time with no zone is read as IST on this page; the selector under the box switches that to PST or to your own zone, and a Unix number or an ISO 8601 string with an offset is always read as written.
- Does the IST to PST difference change with daylight saving time?
- Yes, twice. PST moves its clocks on 8 March and 1 November in 2026, while IST stays at UTC+5:30 all year, so the gap changes by an hour on each of those dates. parsetime computes the offset for the exact instant you enter, so the days around a change come out right as well.
