If you are scheduling a call between San José and Buenos Aires, the overlap window is limited to typical business hours. When it is 9 am in San José it is 12 pm in Buenos Aires — a workable window for scheduling. The latest reasonable overlap is around 2 pm in San José (5 pm in Buenos Aires). Outside this window there is effectively no good overlap for regular office hours.
Scheduling a family call between San José and Buenos Aires takes a little planning. San José is 3 hours behind Buenos Aires, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in San José — around 7 pm — which puts Buenos Aires 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.
