When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Chile Time and Australian Central Time don't overlap on the same weekday. Australian Central Time is 14 hours ahead of Chile Time.
With some flexibility, there’s a workable window outside standard hours:
- 6 PM–8 PM in Chile Time (7 AM–9 AM the next day in Australian Central Time) — suggest 7:00 PM Chile Time (8:30 AM Australian Central Time).
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.
