Milan is 1.5 hours behind Tehran
Best overlap: 9:30 AM to 6:30 PM in Tehran is 8:00 AM to 5:00 PM in Milan.
Book within 9:30 AM to 6:30 PM Tehran time (8:00 AM to 5:00 PM in Milan) and both teams will be at work. Milan is 1.5 hours behind Tehran, but with 9 hours of common ground you can hold morning or afternoon meetings without anyone working odd hours. For part of the year the maths changes: Milan observes daylight saving, Tehran does not, shifting the overlap by an hour.
