PST to IST: quick answer
To convert fixed Pacific Standard Time (PST) to Indian Standard Time (IST), add 13 hours and 30 minutes. For example, 9:00 AM PST is 10:30 PM IST. If you mean current Pacific Time in Los Angeles, the difference is 13 hours 30 minutes during PST and 12 hours 30 minutes during Pacific Daylight Time (PDT).
The calculator defaults to real-world Pacific Time using America/Los_Angeles. Select Fixed PST offset only when the source explicitly means UTC−08:00 throughout the year.
How to convert PST or Pacific Time to IST
- Fixed PST: IST = PST + 13 hours 30 minutes.
- PDT: IST = PDT + 12 hours 30 minutes.
- Real Pacific Time: use the selected date so the converter can apply PST or PDT correctly.
Example: 4:00 PM fixed PST is 5:30 AM IST on the next date. On a date when Los Angeles observes PDT, 4:00 PM Pacific Time is 4:30 AM IST the next date.
PST, PDT and PT are not interchangeable
| Label | UTC offset | IST difference |
|---|---|---|
| PST | UTC−08:00 | IST is 13:30 ahead |
| PDT | UTC−07:00 | IST is 12:30 ahead |
| PT | PST or PDT by date | Use date-aware conversion |
PST is a fixed standard-time abbreviation. PT is the general regional label and changes between PST and PDT where daylight saving applies. Confirm the date and city for a real event.
Common PST to IST conversions
| Pacific time | IST from fixed PST | IST from PDT |
|---|---|---|
| 6:00 AM | 7:30 PM | 6:30 PM |
| 9:00 AM | 10:30 PM | 9:30 PM |
| 12:00 PM | 1:30 AM next day | 12:30 AM next day |
| 3:00 PM | 4:30 AM next day | 3:30 AM next day |
| 6:00 PM | 7:30 AM next day | 6:30 AM next day |
| 9:00 PM | 10:30 AM next day | 9:30 AM next day |
Calendar-date changes
With fixed PST, times from 10:30 AM onward fall on the next IST calendar date. During PDT, the next-date boundary begins at 11:30 AM Pacific Time. Include the date in invitations, release windows and support handoffs.
Best Pacific Time to India meeting window
A practical Pacific-side window is 7:00 AM–9:00 AM PT. It corresponds to 8:30 PM–10:30 PM IST during PST or 7:30 PM–9:30 PM IST during PDT. The overlap is limited, so rotating meeting times may be fairer for recurring teams.
Formula, methodology and verification
Fixed mode applies an exact PST offset of UTC−08:00. Real-world mode uses America/Los_Angeles for the selected date; IST uses Asia/Kolkata at UTC+05:30. Tests cover PST and PDT dates, US transition dates, midnight rollover, month/year boundaries and reciprocal PT → IST → PT checks.
Frequently asked questions
What is the fixed PST to IST difference?
IST is exactly 13 hours and 30 minutes ahead of fixed PST.
What is 9:00 AM PST in IST?
9:00 AM fixed PST is 10:30 PM IST on the same date. If the source is observing PDT, 9:00 AM Pacific Time is 9:30 PM IST.
Why can PST to IST show 12 hours 30 minutes?
That result applies when the selected Pacific location is observing PDT at UTC−07:00. Strict fixed PST remains UTC−08:00 and 13 hours 30 minutes behind IST.
Does India observe daylight saving time?
No. Modern Indian Standard Time remains at UTC+05:30 throughout the year.
Should I choose real-world Pacific Time or fixed PST?
Choose real-world Pacific Time for Los Angeles and most dated West Coast events. Choose fixed PST only when the source explicitly specifies UTC−08:00 regardless of the date.
