When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Christchurch and Riyadh don't overlap on the same weekday. Riyadh is 9 hours behind Christchurch.
With some flexibility, there’s a workable window outside standard hours:
- 4 PM–8 PM in Christchurch (7 AM–11 AM in Riyadh) — suggest 6:00 PM Christchurch (9:00 AM Riyadh).
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.
Note: the working week in Saudi Arabia runs Sunday–Thursday; Friday–Saturday is the weekend, so overlap on those days is limited.
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.
