When to schedule

Standard business hours (9 AM–5 PM, Mon–Fri) in Iran Standard Time and Peru Time don't overlap on the same weekday. Peru Time is 8 hours behind Iran Standard Time.

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

  • 4 PM–8 PM in Iran Standard Time (7 AM–11 AM in Peru Time) — suggest 6:00 PM Iran Standard Time (9:30 AM Peru 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.
