Best time for work calls

If you are scheduling a call between Boston and Hanoi, 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.

Best time for family calls

Scheduling a family call between Boston and Hanoi takes a little planning. Boston is 11 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 Boston — around 7 pm — which puts Hanoi at 6 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.
