Open Meeting Planner →Seoul's electronics and automotive and Athens's shipping and tourism are different worlds, which is exactly why they call each other. The gap is 6 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 09:00–17:00 in Athens. 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 Athens side, Orthodox Easter (Good Friday to Easter Monday, April or May) and Independence Day (25 March).
The shared window is short: 15:00–17:00 Seoul time, 09:00–11:00 in Athens. Guard it for the conversations that need everyone, and let the rest happen in writing. Only Athens changes its clocks, so the gap shifts by an hour twice a year while Seoul stays put.
Seoul is 6 hours ahead of Athens. The gap changes by an hour around the clock changes.
15:00–17:00 Seoul time, which is 09:00–11:00 in Athens — the 2-hour stretch when both are inside 09:00–17:00.
Both work Monday to Friday, so any weekday works.
For the working day, yes — the gap is not wide enough to push office hours across midnight.
