Best time for work calls

If you are scheduling a call between San Diego and Boston, the overlap window is limited to typical business hours. When it is 9 am in San Diego it is 12 pm in Boston — a workable window for scheduling. The latest reasonable overlap is around 2 pm in San Diego (5 pm in Boston). Outside this window there is effectively no good overlap for regular office hours.

Best time for family calls

Scheduling a family call between San Diego and Boston takes a little planning. San Diego is 3 hours behind Boston, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in San Diego — around 7 pm — which puts Boston 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.
