If you are scheduling a call between Athens and Hanoi, the overlap window is limited to typical business hours. When it is 9 am in Athens it is 1 pm in Hanoi — a workable window for scheduling. The latest reasonable overlap is around 1 pm in Athens (5 pm in Hanoi). Outside this window there is effectively no good overlap for regular office hours.
Scheduling a family call between Athens and Hanoi takes a little planning. Athens is 4 hours behind Hanoi, 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 Hanoi at 11 pm. 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.
