If you are scheduling a call between Ho Chi Minh City and São Paulo, there is very limited or no overlap in normal business hours. Consider early-morning or late-evening calls for one side, or use async communication.
Ho Chi Minh City and São Paulo have a comfortable window for a family call — no awkward alarms required. Ho Chi Minh City is 10 hours ahead of São Paulo, which gives you 4 hours of genuine overlap when both sides are free. Aim for between 6 pm and 10 pm in Ho Chi Minh City — that lands at 8 am to 12 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.
