If you are scheduling a call between Hanoi and Vienna, the overlap window is limited to typical business hours. When it is 2 pm in Hanoi it is 9 am in Vienna — a workable window for scheduling. The latest reasonable overlap is around 5 pm in Hanoi (12 pm in Vienna). Outside this window there is effectively no good overlap for regular office hours.
Scheduling a family call between Hanoi and Vienna takes a little planning. Hanoi is 5 hours ahead of Vienna, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in Hanoi — around 7 pm — which puts Vienna at 2 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.
