Best Time to Meet Between Seattle and Sydney

Time difference between Seattle and Sydney

The 17h offset between Seattle and Sydney is not just a number — it reshapes the entire rhythm of collaboration. Sydney clocks out while Seattle is still at lunch. Teams that don't plan this deliberately spend their overlap on firefighting instead of actual work.

The 1h overlap window runs at the edge of both teams' days. For Seattle's side it's a late-morning meeting; for Sydney 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.

Recurring calendar invites for Seattle–Sydney meetings need a DST audit every year. If one city's clocks change before the other's, there's a window — sometimes three weeks, sometimes five — where the same calendar slot lands an hour earlier or later than intended. Always schedule with explicit timezone labels, not just clock times.

Add the rest of your team above and the planner scales to everyone at once. A three-city team spanning Seattle, Sydney, 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.
