How do I convert PST to JST?
PST (Pacific Time (US & Canada)) uses the IANA timezone identifier America/Los_Angeles (standard offset -08:00), while JST (Japan Standard Time) uses Asia/Tokyo (standard offset +09:00). 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 Los Angeles / San Francisco and Tokyo?
Check the rows highlighted with "Best Meeting Overlap" in the 24-hour table above, where both PST and JST fall within standard 9:00 AM – 5:00 PM working hours.
Does PST to JST account for Daylight Saving Time (DST)?
Yes. Castov uses the browser's native IANA tzdb engine (America/Los_Angeles and Asia/Tokyo), which automatically applies official Daylight Saving Time transitions.
