Seoul to Sydney: the time difference

On 2026-10-05 at 9:00 AM in Seoul, it is 11:00 AM in Sydney (Monday, October 5, 2026). Sydney is 2 hours ahead of Seoul.

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. 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.
