Best overlap: 11:00 AM to 6:00 PM in Edinburgh is 8:00 AM to 3:00 PM in Buenos Aires.
For the smoothest call, aim inside 11:00 AM to 6:00 PM in Edinburgh, i.e. 8:00 AM to 3:00 PM in Buenos Aires.

Don't be caught out by clock changes — Edinburgh observes daylight saving and Buenos Aires doesn't, so the offset varies by an hour through the year.
