Open Meeting Planner →Seoul's electronics and automotive and Johannesburg's mining and banking are different worlds, which is exactly why they call each other. Seoul runs 7 hours ahead of Johannesburg.
The working week is Monday to Friday on both sides: roughly 09:00–18:00 in Seoul and 08:00–17:00 in Johannesburg. Watch for Seollal (three days around Lunar New Year, January or February) and Chuseok (three days in September or October) in Seoul and Heritage Day (24 September) and Freedom Day (27 April) in Johannesburg. Replies slow in Seoul during Chuseok and in Johannesburg during mid-December to mid-January.
Only 1 office hour overlap — 16:00–17:00 in Seoul, 09:00–10:00 in Johannesburg — so recurring meetings should hold that slot and everything else can go asynchronous. Neither city observes daylight saving, so the gap holds all year.
Seoul is 7 hours ahead of Johannesburg. The gap is the same all year.
16:00–17:00 Seoul time, which is 09:00–10:00 in Johannesburg — the 1-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.
