Brasília is 3 hours behind Accra
Best overlap: 11:00 AM to 6:00 PM in Accra is 8:00 AM to 3:00 PM in Brasília.
Keep meetings inside 11:00 AM to 6:00 PM in Accra — that maps to 8:00 AM to 3:00 PM in Brasília. Because you share 7 hours of the workday, there's no need to compromise; book the time that suits the meeting, not the map.
