Why people convert PST to Bangkok time
- Scheduling a call from PST to Bangkok: a 10:00 AM start in PST lands at 1:00 AM in Bangkok the next day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +15h gap: PST and Bangkok have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Bangkok is 12:00 AM in PST.
- Coordinating a PST-based team with Bangkok contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM PST" is unambiguous; "3 PM" across a +15h gap is not.
- With a +15h gap there is no shared 9-to-5 window, so alternate the early start: one week PST takes the early slot, the next week Bangkok does.
