Best overlap: 8:00 AM to 4:00 PM in Boston is 10:00 AM to 6:00 PM in Brasília.
Your shared working hours run 8:00 AM to 4:00 PM in Boston (10:00 AM to 6:00 PM in Brasília). Even with Brasília ahead by 2 hours, your workdays overlap by a comfortable 8 hours — plenty of flexibility for both sides. Heads up: because Boston changes its clocks and Brasília doesn't, the difference moves by an hour twice a year. Confirm the overlap around the DST switch.
