Kathmandu is 4.75 hours ahead of Rome
Best overlap: 8:00 AM to 2:00 PM in Rome is 12:45 PM to 6:45 PM in Kathmandu.
Your window to reach both cities is 8:00 AM to 2:00 PM in Rome, which converts to 12:45 PM to 6:45 PM in Kathmandu. A 6-hour overlap gives you real choice here — early or late in the window both work comfortably. 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.
