Why people convert COT to Taiwan time
- Scheduling a call from COT to Taiwan: a 10:00 AM start in COT lands at 11:00 PM in Taiwan, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +13h gap: COT and Taiwan 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 Taiwan is 10:00 PM in COT.
- Watching a live event or market open: COT viewers need 10:00 PM in Taiwan to catch a 9:00 AM start there, and 11:00 AM if the event is anchored to COT.
- Always state the zone abbreviation, not just the hour. "3:00 PM COT" is unambiguous; "3 PM" across a +13h gap is not.
- With a +13h gap there is no shared 9-to-5 window, so alternate the early start: one week COT takes the early slot, the next week Taiwan does.
