Montreal is 2 hours behind Brasília
Best overlap: 10:00 AM to 6:00 PM in Brasília is 8:00 AM to 4:00 PM in Montreal.
Book within 10:00 AM to 6:00 PM Brasília time (8:00 AM to 4:00 PM in Montreal) and both teams will be at work. Montreal is 2 hours behind Brasília, but you'd hardly notice — 8 hours of shared hours makes this feel like working in neighbouring time zones. Daylight saving complicates things slightly: Montreal observes it, Brasília doesn't, so the difference flexes by an hour part of the year.
