Milan 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 Milan.
The overlap falls at 12:45 PM to 6:45 PM in Kathmandu, or 8:00 AM to 2:00 PM if you're in Milan. With 6 hours in common, treat scheduling almost as if the two cities were in the same region. Because only Milan changes its clocks, the overlap above isn't fixed; expect a one-hour shift when Milan enters or leaves daylight saving.
