Best time for work calls

If you are scheduling a call between Sydney and Seattle, the overlap window is limited to typical business hours. When it is 9 am in Sydney it is 4 pm in Seattle — a workable window for scheduling. The latest reasonable overlap is around 10 am in Sydney (5 pm in Seattle). Outside this window there is effectively no good overlap for regular office hours.

Best time for family calls

Scheduling a family call between Sydney and Seattle takes a little planning. Sydney is 17 hours ahead of Seattle, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in Sydney — around 7 pm — which puts Seattle at 2 am. Someone will need to stretch a little, but at least no one's setting a middle-of-the-night alarm. Weekends tend to give the most flexibility if you can agree on a time in advance.
