A 0h time gap separates Seoul (UTC+9) and Tokyo (UTC+9). When you pick up your morning coffee in Tokyo, your counterpart in Seoul is already a few hours into their day. Getting a meeting right means understanding exactly where those working days intersect.
With 8h of shared business hours, there's enough room for one focused daily meeting. The discipline is keeping it exactly that: focused. 0h gaps don't forgive meeting sprawl — a 30-minute standup that runs to 45 minutes starts eating into someone's actual work time. Book it, timebox it, end it on schedule.
For any recurring sync between Seoul and Tokyo, set the calendar invite in one canonical timezone and confirm the other side sees the correct local time. DST transitions can silently shift the effective meeting time by an hour for several weeks without either party noticing until someone is waiting alone on the call.
Add the rest of your team above and the planner scales to everyone at once. A three-city team spanning Seoul, Tokyo, and a third timezone often has less overlap than any two-city pair in isolation — surfacing that constraint early prevents scheduling that works on paper but burns people out in practice.
Seoul is UTC+9 and Tokyo is UTC+9, a difference of 0h. This gap is constant year-round.
The best meeting time is during the 8h of shared business hours — typically 9:00 AM to 5:00 PM GMT+9.
No. Neither Seoul nor Tokyo observes daylight saving time, so the 0h gap is constant year-round.
