Munich 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 Munich.
Tehran and Munich overlap from 9:30 AM to 6:30 PM (Tehran) to the equivalent 8:00 AM to 5:00 PM in Munich — that's your meeting window. You won't be short on options — 9 hours of overlap leaves space for recurring syncs and ad-hoc calls alike. One seasonal catch: Munich springs forward and falls back, but Tehran doesn't, so the gap changes by an hour for several months of the year.
