Vienna is 4 hours ahead of Brasília
Best overlap: 8:00 AM to 2:00 PM in Brasília is 12:00 PM to 6:00 PM in Vienna.
Both teams are at their desks between 8:00 AM to 2:00 PM in Brasília and 12:00 PM to 6:00 PM in Vienna. You won't be short on options — 6 hours of overlap leaves space for recurring syncs and ad-hoc calls alike. Note the seasonal wrinkle: when Vienna is on daylight saving and Brasília isn't, the gap between them grows or shrinks by an hour.
