PST to IST Converter – Pacific Time to India Time

PST to IST conversion: India Standard Time (UTC+5:30) is 13 hours 30 minutes ahead of Pacific Standard Time (UTC−8) and 12 hours 30 minutes ahead of Pacific Daylight Time (UTC−7), which California uses from March to November. The Kalinga Times converter below picks the right offset for any date.

Pacific Time to India time: quick answers

To convert Pacific Time to IST, add 13 hours 30 minutes in winter (PST) or 12 hours 30 minutes in summer (PDT); the result is often the next calendar day in India. The table lists common California times.

Converting from UTC instead, for example a server log or flight schedule? Use the utc to ist converter, which skips daylight saving entirely.

PST, PDT and IST offsets with 2026–2027 switch dates

Pacific Time changes twice a year while IST never changes, so the India–California gap is 13 h 30 min for about four months and 12 h 30 min for about eight months.

Clocks in California go forward on Sunday 8 March 2026 at 2:00 am and back on Sunday 1 November 2026 at 2:00 am local time; in 2027 the dates are 14 March and 7 November. The rule is the second Sunday in March to the first Sunday in November, set by the US Energy Policy Act of 2005 (15 U.S. Code § 260a), checked on 12 October 2026 against the IANA time zone database. India does not observe daylight saving: IST is UTC+5:30 all year.

India–California business hours overlap

A normal India working day (09:00–18:00 IST) and a California working day (09:00–17:00 local) do not overlap at all. The practical windows are early morning in California, which is evening in India, or late evening in California, which is the next morning in India. Working hours are in bold.

In summer, 20:00–22:00 IST lands at 7:30–9:30 am PDT, the most common slot for India–Bay Area stand-ups. In winter the same India evening is one hour earlier in California (6:30–8:30 am PST), so many teams move the call to 21:00–23:00 IST.

Which places use Pacific Time?

Pacific Time (America/Los_Angeles in the IANA database) covers California, Washington, most of Oregon and most of Nevada; British Columbia in Canada keeps the same clock. A conversion from any of these places to India gives the same result.

Scheduling tips for India–US West Coast calls

• Write both times in invites, for example “21:00 IST / 08:30 PDT”, and add the date for India because it is often the next day.
• The week after 8 March and the week after 1 November, recurring calls shift by one hour for India; re-check them.
• “PT” in an email means whichever of PST or PDT is in force; use the converter with the meeting date instead of guessing.
• For deadlines like “end of day PT”, 11:59 pm PDT is 12:29 pm IST the next day, and 11:59 pm PST is 1:29 pm IST the next day.
