About PST to IST Time
PST covers Los Angeles, San Francisco, Seattle, Las Vegas and Vancouver. IST covers Delhi, Mumbai, Bengaluru, Hyderabad, Chennai and Kolkata.
Normal working days barely overlap: when one side starts, the other has finished. Calls usually mean early morning for one and evening for the other — the timeline above shows exactly how early.
The clocks do not change on the same day, so a recurring meeting can shift by an hour in March and again in November. Check any standing call in the two weeks after each change.
How it works
India Standard Time is 13.5 hours ahead of Pacific Time (Los Angeles) between November and March, and 12.5 hours ahead the rest of the year.
- Take the PST time you want to convert.
- Add 13.5 hours between autumn and spring, or 12.5 hours during daylight saving.
- Roll the date forward or back if the result crosses midnight.
The gap changes because the two places start and end daylight saving on different dates — for a few weeks each spring and autumn the difference is an hour off its usual value. The converter above uses the live IANA time zone database, so it is right on those days too.
Zone details: PST is −8 in winter and −7 in summer (UTC), IST is +5:30 all year.
Examples
A working day in PST, seen from IST (during daylight saving):
| PST | IST |
|---|---|
| 09:00 PST | 21:30 IST |
| 12:00 PST | 00:30 IST (next day) |
| 15:00 PST | 03:30 IST (next day) |
| 18:00 PST | 06:30 IST (next day) |
| 21:00 PST | 09:30 IST (next day) |
Meetings usually work best where the two working days overlap. Drag the timeline above to see the overlap for any hour, or use the full time zone converter for any other pair of cities.
