Open Meeting Planner →Seoul's electronics and automotive and Lisbon's tourism and technology are different worlds, which is exactly why they call each other. The gap is 8 hours, with Seoul the one whose clock reads later.
The working week is Monday to Friday on both sides: roughly 09:00–18:00 in Seoul and 09:00–18:00 in Lisbon. On the Seoul side the dates that break a schedule are Seollal (three days around Lunar New Year, January or February) and Chuseok (three days in September or October); on the Lisbon side, Freedom Day (25 April) and Portugal Day (10 June). Replies slow in Seoul during Chuseok and in Lisbon during August.
The office days never overlap; the workable slots are Lisbon's early morning against Seoul's evening. Rotate the inconvenience rather than fixing it on one side. Only Lisbon changes its clocks, so the gap shifts by an hour twice a year while Seoul stays put.
Seoul is 8 hours ahead of Lisbon. The gap changes by an hour around the clock changes.
There is no hour when both offices are open. The closest is early morning in Lisbon against the end of the day in Seoul; alternate which side takes the awkward slot.
Alternate. A standing call that is always 07:00 for Lisbon or always 19:00 for Seoul is resented within a month; rotating it keeps both sides in the room.
For the working day, yes — the gap is not wide enough to push office hours across midnight.
