Why people convert Bangkok to COT time
- Scheduling a call from Bangkok to COT: a 10:00 AM start in Bangkok lands at 10:00 PM in COT the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -12h gap: Bangkok and COT 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 COT is 9:00 PM in Bangkok.
- Watching a live event or market open: Bangkok viewers need 9:00 PM in COT to catch a 9:00 AM start there, and 12:00 PM if the event is anchored to Bangkok.
- Always state the zone abbreviation, not just the hour. "3:00 PM ICT" is unambiguous; "3 PM" across a -12h gap is not.
- With a -12h gap there is no shared 9-to-5 window, so alternate the early start: one week Bangkok takes the early slot, the next week COT does.
