If you are scheduling a call between Tokyo and Hanoi, the overlap window is limited to typical business hours. When it is 11 am in Tokyo it is 9 am in Hanoi — a workable window for scheduling. The latest reasonable overlap is around 5 pm in Tokyo (3 pm in Hanoi). Outside this window there is effectively no good overlap for regular office hours.
Scheduling a family call between Tokyo and Hanoi takes a little planning. Tokyo is 2 hours ahead of Hanoi, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in Tokyo — around 7 pm — which puts Hanoi at 5 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.
