About the São Paulo-Boston gap
São Paulo sits in the America/Sao_Paulo time zone (UTC−3), while Boston uses America/New_York (EDT). That puts Boston 1 hour behind of São Paulo right now.
These two cities do not handle daylight saving the same way, one adjusts its clocks seasonally and the other does not. The difference between them therefore moves by an hour twice a year, which is a common cause of missed meetings. The clocks above always show the live position rather than an assumed offset.
For scheduling, the practical overlap runs from 10:00 to 17:00 in São Paulo. Booking inside that band means neither party is dialling in before breakfast or after dinner.
