Time difference between Seoul and Sydney

Sydney is 1 hour ahead of Seoul

Seoul, South Korea is UTC+9 · Sydney, Australia is UTC+10 — on standard time

The gap is not the same all year

Every converter gives one number for this pair. That number is right for most of the year and wrong for part of it, because Seoul does not change its clocks and Sydney goes forward on the first Sunday in October and back on the first Sunday in April.

Seoul stays put all year while Sydney moves, so the gap changes twice a year from Sydney's side alone. A recurring meeting set in Seoul's calendar will drift by an hour without anyone touching it.
