Melbourne is 5.25 hours ahead of Kathmandu
Best overlap: 8:45 AM to 12:45 PM in Kathmandu is 2:00 PM to 6:00 PM in Melbourne.
The hours that work for both Kathmandu and Melbourne are 8:45 AM to 12:45 PM (Kathmandu) and 2:00 PM to 6:00 PM (Melbourne). Melbourne is 5.25 hours ahead of Kathmandu, leaving about 4 hours of shared hours — plan recurring calls early in that window to leave buffer. A quick caveat — Melbourne's clocks move for daylight saving and Kathmandu's don't, so the times here are right for only part of the year.
