Time Difference Between Seoul and Sydney

12 hours Sydney is behind Seoul

Seoul and Sydney are separated by 13 hours, which shapes how residents, professionals, and travelers coordinate across both cities. Sydney observes daylight saving time; Seoul does not. The gap shifts by one hour during Canada’s DST period.

Market hours in Seoul and Sydney do not overlap, so real-time coordination between offices requires one side to work outside standard hours. Futures desks and global trading operations typically staff accordingly. 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.
