If you are scheduling a call between Hanoi and São Paulo, there is very limited or no overlap in normal business hours. Consider early-morning or late-evening calls for one side, or use async communication.
Scheduling a family call between Hanoi and São Paulo takes a little planning. Hanoi is 10 hours ahead of São Paulo, 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 São Paulo at 9 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.
