Rome is 4.75 hours behind Kathmandu
Best overlap: 12:45 PM to 6:45 PM in Kathmandu is 8:00 AM to 2:00 PM in Rome.
Kathmandu and Rome overlap from 12:45 PM to 6:45 PM (Kathmandu) to the equivalent 8:00 AM to 2:00 PM in Rome — that's your meeting window. Rome is 4.75 hours behind Kathmandu, yet you get a full 6 hours of shared hours — enough to schedule around lunches, focus time, and preferences with ease. A quick caveat — Rome's clocks move for daylight saving and Kathmandu's don't, so the times here are right for only part of the year.
