Why people convert South Korea to CET time
- Scheduling a call from South Korea to CET: a 10:00 AM start in South Korea lands at 2:00 AM in CET, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -8h gap: South Korea and CET 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 CET is 1:00 AM in South Korea.
- Watching a live event or market open: South Korea viewers need 1:00 AM in CET to catch a 9:00 AM start there, and 8:00 AM if the event is anchored to South Korea.
- Always state the zone abbreviation, not just the hour. "3:00 PM KST" is unambiguous; "3 PM" across a -8h gap is not.
- With a -8h gap there is no shared 9-to-5 window, so alternate the early start: one week South Korea takes the early slot, the next week CET does.
