If you are scheduling a call between Athens and Sydney, the overlap window is limited to typical business hours. When it is 9 am in Athens it is 4 pm in Sydney — a workable window for scheduling. The latest reasonable overlap is around 10 am in Athens (5 pm in Sydney). Outside this window there is effectively no good overlap for regular office hours.
Scheduling a family call between Athens and Sydney takes a little planning. Athens is 7 hours behind Sydney, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in Athens — around 7 pm — which puts Sydney 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.
