When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Adelaide and Istanbul don't overlap on the same weekday. Istanbul is 7 hours behind Adelaide.
With some flexibility, there’s a workable window outside standard hours:
- 3 PM–8 PM in Adelaide (7 AM–12 PM in Istanbul) — suggest 5:00 PM Adelaide (9:30 AM Istanbul).
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.
