Time difference between Seoul and Anchorage

Anchorage is 17 hours behind Seoul

Seoul, South Korea is UTC+9 · Anchorage, the United States is UTC−9 — 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 Anchorage goes forward on the second Sunday in March and back on the first Sunday in November.

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

When they can both be at their desks

Nine-to-five in Seoul and nine-to-five in Anchorage do not overlap at all. With 17 hours between them, one side is always outside working hours, and the practical question is which side takes the early start or the late finish rather than when to meet.
