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