When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Rio de Janeiro and Colombo don't overlap on the same weekday. Colombo is 9 hours ahead of Rio de Janeiro.
With some flexibility, there’s a workable window outside standard hours:
- 7 AM–12 PM in Rio de Janeiro (3 PM–8 PM in Colombo) — suggest 9:00 AM Rio de Janeiro (5:30 PM Colombo).
This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.
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.
