Tel Aviv is 6 hours ahead of São Paulo
Best overlap: 8:00 AM to 12:00 PM in São Paulo is 2:00 PM to 6:00 PM in Tel Aviv.
For the smoothest call, aim inside 8:00 AM to 12:00 PM in São Paulo, i.e. 2:00 PM to 6:00 PM in Tel Aviv. Tel Aviv is 6 hours ahead of São Paulo, so the practical overlap is about 4 hours — generous enough for meetings, tight enough to be worth booking ahead. For part of the year the maths changes: Tel Aviv observes daylight saving, São Paulo does not, shifting the overlap by an hour.
