PST to IST Time Converter (and IST to PST): DST-Safe Guide
“PST to IST” is a common search for scheduling with India, but the tricky part is that PST is often used as shorthand for Pacific Time (PT), which switches between PST and PDT. This guide gives you a reliable method, plus a shareable converter link.
Quick answer: IST is 12.5–13.5 hours ahead of Pacific Time
India Standard Time (IST) is fixed at UTC+5:30 (no DST). Pacific Time changes with daylight saving time:
- When Pacific Time is PST (standard time), IST is 13.5 hours ahead.
- When Pacific Time is PDT (daylight time), IST is 12.5 hours ahead.
Common PST/PDT → IST conversions
Here are a few examples that cover the most common scheduling cases:
- 9:00 AM PT → 9:30 PM IST (same day)
- 12:00 PM PT → 12:30 AM IST (next day)
- 5:00 PM PT → 5:30 AM IST (next day)
Why this conversion is easy to get wrong (DST + day rollover)
- People say “PST” year-round, but many dates are actually PDT.
- PT → IST often crosses midnight, so the day changes.
The DST transition weeks (March/November in the U.S.) are where “PST to IST” shortcuts cause missed meetings.
The DST-safe way to convert PT ↔ IST (works every time)
- Always include the date.
- Convert using cities (e.g., Los Angeles ↔ New Delhi) so DST rules apply correctly.
- Share a link so everyone sees the same moment.
Use the time zone converter for a specific timestamp. If you’re trying to find a fair meeting window between PT and IST working hours, use the Meeting Planner. If you’re coordinating more than two locations (e.g., PT + IST + UK), use Compare Cities.
Reverse conversion: IST → Pacific Time
When converting from IST back to PT, remember that IST is ahead — so you often go to the previous day in Pacific Time.
- 10:00 AM IST → 8:30 PM PT (previous day)
- 6:00 PM IST → 4:30 AM PT (same day)
Best practice for meeting invites (PT ↔ IST)
- Write the time in both zones (e.g., “10:00 AM PT / 10:30 PM IST”).
- Include a converter link for the exact timestamp.
- If your team is spread out, use the Meeting Planner to find overlap hours.
