Best overlap: 8:00 AM to 3:00 PM in Buenos Aires is 11:00 AM to 6:00 PM in Edinburgh.
For a call that suits both sides, look at 8:00 AM to 3:00 PM in Buenos Aires / 11:00 AM to 6:00 PM in Edinburgh. Despite the 3-hour difference, a 7-hour overlap keeps things simple and gives both teams breathing room. Finally, Edinburgh observes daylight saving and Buenos Aires doesn't, so this window shifts by an hour for part of the year — recheck it each spring and autumn.
