Time Difference Between Seoul and New York City

13 hours New York City is behind Seoul

Market hours in New York City and Seoul do not overlap, so real-time coordination between offices requires one side to work outside standard hours.

Both cities carry significant weight in their regional economies, and cross-border business activity between them spans banking, logistics, and professional services.

Knowing when both cities are simultaneously open for business is the first step in structuring meetings, deal timelines, and reporting windows.
