If you are scheduling a call between São Paulo and San Diego, the overlap window is limited to typical business hours. When it is 1 pm in São Paulo it is 9 am in San Diego — a workable window for scheduling. The latest reasonable overlap is around 5 pm in São Paulo (1 pm in San Diego). Outside this window there is effectively no good overlap for regular office hours.
São Paulo and San Diego have a comfortable window for a family call — no awkward alarms required. São Paulo is 4 hours ahead of San Diego, which gives you 4 hours of genuine overlap when both sides are free. Aim for between 6 pm and 10 pm in São Paulo — that lands at 2 pm to 6 pm in San Diego, after the school run and before anyone's ready for bed. For a Sunday catch-up or a midweek check-in, this is the sweet spot.
