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