São Paulo is 5 hours behind Milan

Best overlap: 1:00 PM to 6:00 PM in Milan is 8:00 AM to 1:00 PM in São Paulo.

The overlap falls at 1:00 PM to 6:00 PM in Milan, or 8:00 AM to 1:00 PM if you're in São Paulo. You get roughly 5 hours of shared time, so aim for the middle of that window to keep the call comfortable for both teams. Heads up: because Milan changes its clocks and São Paulo doesn't, the difference moves by an hour twice a year. Confirm the overlap around the DST switch.
