If you are scheduling a call between Dallas and São Paulo, the overlap window is limited to typical business hours. When it is 9 am in Dallas it is 11 am in São Paulo — a workable window for scheduling. The latest reasonable overlap is around 3 pm in Dallas (5 pm in São Paulo). Outside this window there is effectively no good overlap for regular office hours.
Dallas and São Paulo have a comfortable window for a family call — no awkward alarms required. Dallas is 2 hours behind São Paulo, which gives you about an hour of genuine overlap when both sides are free. Aim for between 6 pm and 7 pm in Dallas — that lands at 8 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.
