Best overlap: 1:00 PM to 6:00 PM in Amsterdam is 8:00 AM to 1:00 PM in Rio de Janeiro.
If you set up a recurring sync, 1:00 PM to 6:00 PM in Amsterdam (8:00 AM to 1:00 PM in Rio de Janeiro) is the natural home for it. Rio de Janeiro is 5 hours behind Amsterdam, leaving about 5 hours of daily overlap — enough for most meetings if you don't leave them too late in the day. Keep an eye on the calendar — Amsterdam observes daylight saving and Rio de Janeiro doesn't, which nudges this window by an hour twice a year.
