Open Meeting Planner →Tokyo and Seoul share electronics and finance as core industries, which is where the traffic between them comes from. The two keep the same clock, so the only thing to plan around is the calendar.
Both cities work Monday to Friday, Tokyo typically 09:00–18:00 and Seoul 09:00–18:00 local time. On the Tokyo side the dates that break a schedule are Golden Week (29 April to 5 May) and Obon (around 13–16 August); on the Seoul side, Seollal (three days around Lunar New Year, January or February) and Chuseok (three days in September or October). Replies slow in Tokyo during Golden Week and the year-end break and in Seoul during Chuseok.
Any slot inside 09:00–18:00 works for both, so pick the day rather than the hour. Neither city observes daylight saving, so the gap holds all year.
None — Tokyo and Seoul keep the same clock.
Both work Monday to Friday, so any weekday works.
The ones that most often surprise the other side are Golden Week (29 April to 5 May) and Obon (around 13–16 August) in Tokyo and Seollal (three days around Lunar New Year, January or February) and Chuseok (three days in September or October) in Seoul.
No. Neither city observes daylight saving, so the difference never changes.
