If you are scheduling a call between Brasília and San Francisco, the overlap window is limited to typical business hours. When it is 1 pm in Brasília it is 9 am in San Francisco — a workable window for scheduling. The latest reasonable overlap is around 5 pm in Brasília (1 pm in San Francisco). Outside this window there is effectively no good overlap for regular office hours.
Scheduling a family call between Brasília and San Francisco takes a little planning. Brasília is 4 hours ahead of San Francisco, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in Brasília — around 7 pm — which puts San Francisco at 3 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.
