When it is 9 am in Washington, D.C. it is 10 am in São Paulo — a workable window for scheduling. The latest reasonable overlap is around 4 pm in Washington, D.C. (5 pm in São Paulo). Outside this window there is effectively no good overlap for regular office hours.
Washington, D.C. and São Paulo have a comfortable window for a family call — no awkward alarms required. Washington, D.C. is 1 hour behind São Paulo, which gives you 2 hours of genuine overlap when both sides are free. Aim for between 6 pm and 8 pm in Washington, D.C. — that lands at 7 pm to 9 pm in São Paulo, 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.
