Why people convert Seoul to COT time
- Scheduling a call from Seoul to COT: a 10:00 AM start in Seoul lands at 8:00 PM in COT the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -14h gap: Seoul 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 7:00 PM in Seoul.
- Watching a live event or market open: Seoul viewers need 7:00 PM in COT to catch a 9:00 AM start there, and 2:00 PM if the event is anchored to Seoul.
- Always state the zone abbreviation, not just the hour. "3:00 PM KST" is unambiguous; "3 PM" across a -14h gap is not.
- With a -14h gap there is no shared 9-to-5 window, so alternate the early start: one week Seoul takes the early slot, the next week COT does.
