Athens is 3.75 hours behind Kathmandu
Best overlap: 11:45 AM to 6:45 PM in Kathmandu is 8:00 AM to 3:00 PM in Athens.
The hours that work for both Kathmandu and Athens are 11:45 AM to 6:45 PM (Kathmandu) and 8:00 AM to 3:00 PM (Athens). Athens is 3.75 hours behind Kathmandu, yet you get a full 7 hours of shared hours — enough to schedule around lunches, focus time, and preferences with ease. A quick caveat — Athens's clocks move for daylight saving and Kathmandu's don't, so the times here are right for only part of the year.
