Context for scheduling
Seoul (South Korea)
Working hours: 09:00–18:00 (one-hour lunch around 12:00). Workweek: Monday to Friday.
Avoid scheduling around major holidays like Lunar New Year (Seollal) and Chuseok, when many offices close for several days. Friday late-afternoon meetings are common but usually short.
San Francisco (USA)
Working hours: 09:00–18:00, tech often later. Workweek: Monday to Friday.
Tech industry takes the week between Christmas and New Year as effective shutdown. Thanksgiving week is also quiet.
