Business hours: calls and meetings
If both sides work from 09:00 to 18:00 local time, the workdays overlap from 10:00 to 18:00 Brasília time, which is 09:00 to 17:00 on UTC-4: 8 shared hours. A 09:00 start on UTC-4 is already 10:00 in Brasília, and the Brasília workday ends 1 hour before the local one, so the best slots for a call with Brasília are late morning and early afternoon. Always state the zone when you send an invitation ("14:00 Brasília time"), and use the meeting planner to compare several cities at once, or the time zone converter for an exact date.
One zone for five states in the Center-West and North
UTC-4 is the zone of the Center-West states Mato Grosso and Mato Grosso do Sul, and of Rondônia, Roraima and most of Amazonas, including Manaus. It is also the zone with the most municipalities outside Brasília time: 337, against 35 on UTC-5. Airline tickets, bus timetables and bank cutoffs there always use local time, so check which side of the border a schedule refers to.
