Sydney to Seoul: the time difference
On 2026-10-05 at 9:00 AM in Sydney, it is 7:00 AM in Seoul (Monday, October 5, 2026). Seoul is 2 hours behind of Sydney.
Sydney’s summer is the northern hemisphere’s winter. Its daylight-saving changes can move in the opposite direction from those in North America, making a single year-round difference unreliable. Seoul and Tokyo currently share the same UTC offset. Calls with North America commonly cross midnight, so include the weekday when sharing a Seoul meeting time.
