Atlanta is 1 hour behind São Paulo

São Paulo and Atlanta overlap from 9:00 AM to 6:00 PM (São Paulo) to the equivalent 8:00 AM to 5:00 PM in Atlanta — that's your meeting window. A 9-hour overlap gives you real choice here — early or late in the window both work comfortably. Note the seasonal wrinkle: when Atlanta is on daylight saving and São Paulo isn't, the gap between them grows or shrinks by an hour.
