Seattle and Sydney have a 17-hour time difference. For remote teams, there are 2 working hours of daily overlap in standard schedules (9–18).

The best meeting window is 17:00–18:00 Seattle time (10:00–11:00 Sydney time).

The 2-hour overlap is a narrow but valuable window — reserve it for critical decisions and blockers. Outside of it, async-first processes keep work flowing: structured tickets, recorded walkthroughs, and clear written context.

Sydney opens the workday first, 17 hours ahead of Seattle. A common pattern: Seattle starts with async context from Sydney, the overlap window handles live decisions, and Sydney closes with a clear handoff for Seattle to act on overnight.
