When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Alaska Time and Iran Standard Time don't overlap on the same weekday. Iran Standard Time is 12 hours ahead of Alaska Time.
With some flexibility, there’s a workable window outside standard hours:
- 7 AM–9 AM in Alaska Time (6 PM–8 PM in Iran Standard Time) — suggest 8:00 AM Alaska Time (7:30 PM Iran Standard 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.
