Brasília is 2 hours ahead of Miami
Best overlap: 8:00 AM to 4:00 PM in Miami is 10:00 AM to 6:00 PM in Brasília.
8:00 AM to 4:00 PM in Miami is when Brasília is also working, at 10:00 AM to 6:00 PM their time. Even with Brasília ahead by 2 hours, your workdays overlap by a comfortable 8 hours — plenty of flexibility for both sides. Because only Miami changes its clocks, the overlap above isn't fixed; expect a one-hour shift when Miami enters or leaves daylight saving.
