When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Buenos Aires and Christchurch don't overlap on the same weekday. Christchurch is 15 hours ahead of Buenos Aires.
With some flexibility, there’s a workable window outside standard hours:
- 4 PM–8 PM in Buenos Aires (7 AM–11 AM the next day in Christchurch) — suggest 6:00 PM Buenos Aires (9:00 AM Christchurch).
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.
