Time Difference Between Seoul and Sydney

How far apart are Seoul and Sydney?

Sydney (Australia) runs 1 hour ahead of Seoul (South Korea). In practical terms, the working day in Sydney starts while Seoul is still in the early hours or asleep, which is what makes scheduling between the two take a little planning.

Best time to schedule a call or meeting

The comfortable window — when both cities are inside normal 9-to-5 hours — runs from about 9:00 AM to 4:00 PM in Seoul time, roughly 7 hours. Schedule calls inside that band and neither side is working unsocial hours.

A note on daylight saving

The difference shown here reflects the current offset between Seoul and Sydney. Because regions switch to and from daylight saving on different dates — and some do not observe it at all — the gap can move by an hour for a few weeks each spring and autumn. If you are booking something months ahead, it is worth re-checking close to the date.
