Seoul

Seoul is 13 hours ahead of Columbus right now.
Does the gap change?
The gap isn't fixed. Columbus changes its clocks for daylight saving time and Seoul doesn't, so the difference moves during the year:
- From around November 2, 2026: Seoul ahead by 14 hours
- From around March 15, 2027: Seoul ahead by 13 hours
Best time to meet
Normal office hours in Seoul and Columbus don't overlap. The most workable window is 6 PM to 10 PM in Columbus, which is 7 AM to 11 AM in Seoul, with one side starting early or finishing late.
For a recurring meeting, it's fairest to rotate which city takes the inconvenient slot.
