IST to PST time
PST is 12 hours 30 minutes behind IST.
Time difference between IST and PST
PST is 12 hours 30 minutes behind IST. IST is on India Standard Time (UTC+05:30) and PST is on Pacific Daylight Time (PDT (UTC−07:00)).
The gap is not constant. Because of daylight saving it varies from 12 hours 30 minutes to 13 hours 30 minutes over the year.
Convert IST time to PST time
These examples use the current offsets, UTC+05:30 for IST and UTC−07:00 for PST. Use the converter above for any other time or date.
PST is behind, so from midnight to 12:30 PM in IST it is still the previous calendar day in PST.

Best time to call or meet: IST and PST working hours
The standard 9:00 AM to 5:00 PM working days in IST and PST do not overlap.
Between 8:00 AM and 8:00 PM, both cities are awake from 8:00 AM to 8:30 AM in IST (7:30 PM to 8:00 PM in PST), which usually means an early start or a late finish for one side.
Weekends, public holidays and local working weeks differ by country, so check those before booking.
Daylight saving time in India Standard Time and Pacific Time
India Standard Time does not change its clocks for daylight saving, so its UTC offset stays the same all year.
Pacific Time observes daylight saving time. Its next change is on Nov 1, 2026 at 2:00 AM, when clocks go back 1 hour (UTC−07:00 to UTC−08:00).
