Time difference between Seoul and Lisbon

Lisbon is 8 hours behind Seoul

Seoul, South Korea is UTC+9 · Lisbon, Portugal is UTC — 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 Lisbon goes forward on the last Sunday in March and back on the last Sunday in October.

Seoul stays put all year while Lisbon moves, so the gap changes twice a year from Lisbon'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 Lisbon do not overlap at all. With 8 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.
