Best overlap: 11:00 AM to 6:00 PM in Edinburgh is 8:00 AM to 3:00 PM in São Paulo.
Keep meetings inside 11:00 AM to 6:00 PM in Edinburgh — that maps to 8:00 AM to 3:00 PM in São Paulo. Despite the 3-hour difference, a 7-hour overlap keeps things simple and gives both teams breathing room. Finally, Edinburgh observes daylight saving and São Paulo doesn't, so this window shifts by an hour for part of the year — recheck it each spring and autumn.
