FAQ
How many hours between New York and Seoul?
Seoul is 13 hours ahead of New York (+13 hours).
When is the best time for a meeting?
There is no time that suits both: New York works 09:00–17:00 and Seoul works 09:00–18:00 locally, and those never coincide. Someone has to take the call outside office hours.
