When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Rio de Janeiro and Chongqing don't overlap on the same weekday. Chongqing is 11 hours ahead of Rio de Janeiro.
With some flexibility, there’s a workable window outside standard hours:
- 7 AM–9 AM in Rio de Janeiro (6 PM–8 PM in Chongqing) — suggest 8:00 AM Rio de Janeiro (7:00 PM Chongqing).
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.
