When to schedule

Standard business hours (9 AM–5 PM, Mon–Fri) in Peru Time and Iran Standard Time don't overlap on the same weekday. Iran Standard Time is 9 hours ahead of Peru Time.

With some flexibility, there’s a workable window outside standard hours:

  • 7 AM–12 PM in Peru Time (3 PM–8 PM in Iran Standard Time) — suggest 9:00 AM Peru Time (5:30 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.

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.
