When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Los Angeles and Tehran don't overlap on the same weekday. Tehran is 11 hours ahead of Los Angeles.
With some flexibility, there’s a workable window outside standard hours:
- 7 AM–10 AM in Los Angeles (5 PM–8 PM in Tehran) — suggest 8:00 AM Los Angeles (6:30 PM Tehran).
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.
