If you are scheduling a call between Hanoi and Sydney, the overlap window is limited to typical business hours. When it is 9 am in Hanoi it is 12 pm in Sydney β a workable window for scheduling. The latest reasonable overlap is around 2 pm in Hanoi (5 pm in Sydney). Outside this window there is effectively no good overlap for regular office hours.
Scheduling a family call between Hanoi and Sydney takes a little planning. Hanoi is 3 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 Hanoi β around 7 pm β which puts Sydney at 10 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.
