When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Rio de Janeiro and Sydney don't overlap on the same weekday. Sydney is 13 hours ahead of Rio de Janeiro.
With some flexibility, there’s a workable window outside standard hours:
- 6 PM–8 PM in Rio de Janeiro (7 AM–9 AM the next day in Sydney) — suggest 7:00 PM Rio de Janeiro (8:00 AM Sydney).
This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.
This window may shift by an hour during daylight saving time.
Public holidays in 2026
National public holidays can affect availability — a counterpart is likely off work on their own holidays, so it's worth planning meetings and deadlines around them.
