Why people convert Bangkok to PST time
- Scheduling a call from Bangkok to PST: a 10:00 AM start in Bangkok lands at 7:00 PM in PST the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -15h gap: Bangkok and PST 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 PST is 6:00 PM in Bangkok.
- Keeping family and friends in sync: knowing that 8:00 PM in Bangkok is 5:00 AM in PST makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM ICT" 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 Bangkok takes the early slot, the next week PST does.
