Frequently Asked Questions (IST → PST)

How do I convert IST to PST?

IST (India Standard Time) uses the IANA timezone identifier Asia/Kolkata (standard offset +05:30), while PST (Pacific Time (US & Canada)) uses America/Los_Angeles (standard offset -08:00). Use the interactive slider or the 24-hour table above to convert any hour accurately with automatic Daylight Saving Time (DST) adjustment.

What are the best meeting hours between Mumbai / Bengaluru and Los Angeles / San Francisco?

Check the rows highlighted with "Best Meeting Overlap" in the 24-hour table above, where both IST and PST fall within standard 9:00 AM – 5:00 PM working hours.

Does IST to PST account for Daylight Saving Time (DST)?

Yes. Castov uses the browser's native IANA tzdb engine (Asia/Kolkata and America/Los_Angeles), which automatically applies official Daylight Saving Time transitions.
