When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Tehran and Vancouver don't overlap on the same weekday. Vancouver is 10 hours behind Tehran.
With some flexibility, there’s a workable window outside standard hours:
- 6 PM–8 PM in Tehran (7 AM–9 AM in Vancouver) — suggest 7:00 PM Tehran (8:30 AM Vancouver).
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.
