The 1h offset between Hong Kong and Tokyo is not just a number — it reshapes the entire rhythm of collaboration. Tokyo clocks out while Hong Kong is still at lunch. Teams that don't plan this deliberately spend their overlap on firefighting instead of actual work.
The 7h overlap window runs at the edge of both teams' days. For Hong Kong's side it's a late-morning meeting; for Tokyo it's early afternoon. Neither is painful, which is exactly why it works. Anchor your recurring sync here and treat the rest of the day as async territory.
For any recurring sync between Hong Kong 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 Hong Kong, 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.
Hong Kong is UTC+8 and Tokyo is UTC+9, a difference of 1h. This gap is constant year-round.
