PST is 13h30m behind IST. Subtract 13 hours 30 minutes from IST to get PST. The best India → US-West-Coast call windows are 7:30 – 9:30 PM IST (6:00 – 8:00 AM PST the same day) or 9:30 AM – 12:00 PM IST (8:00 – 10:30 PM PST the previous day). During US daylight saving the gap becomes 12h30m and windows shift an hour.
PST is currently 12h30m behind IST.
Right now New Delhi / Mumbai (India) is on GMT+5:30 (UTC+5:30) and Los Angeles / San Francisco (US West Coast) on PDT (UTC-7). This flips back to the standard IST/PST gap once daylight saving ends.
Live clocks above use each region's current local time (DST-aware). The reference table below uses the fixed IST → PST standard offset — see the DST section for how the gap changes across the year.

Daylight saving and how the gap changes
IST stays at UTC+5:30 year-round because India does not observe DST. The US Pacific zone switches to PDT (UTC-7) from the second Sunday of March to the first Sunday of November. So the India ↔ Pacific-Coast gap is 13h30m in US winter and 12h30m in US summer.
Common mistake: abbreviation collision
This page treats "IST" as India Standard Time (Asia/Kolkata, UTC+5:30). Irish and Israel Standard Time share the abbreviation but are different zones with different offsets.
Frequently asked questions
- What is the time difference between IST and PST?
- IST (India Standard Time) is 13 hours and 30 minutes ahead of PST (US Pacific Standard Time). When it's 10:00 AM IST in Mumbai, it's 8:30 PM PST the previous day in Los Angeles.
- What time is 9 AM IST in PST?
- 9:00 AM IST is 7:30 PM PST the previous day.
- What time is 6 PM IST in PST?
- 6:00 PM IST is 4:30 AM PST the same day.
- Does daylight saving affect the India ↔ US-West-Coast gap?
- Yes. From mid-March to early November the US is on PDT (UTC-7) instead of PST, so the gap becomes 12h30m rather than 13h30m. India does not observe DST.
- When is the best time to schedule an India → US-West-Coast meeting?
- 7:30 – 9:30 PM IST (6:00 – 8:00 AM PST) works before the LA team's workday. The alternative is 9:30 AM – 12:00 PM IST (8:00 – 10:30 PM PST the previous day). Rotating between the two shares the early / late burden.
