Kathmandu is 4.75 hours ahead of Prague
Best overlap: 8:00 AM to 2:00 PM in Prague is 12:45 PM to 6:45 PM in Kathmandu.
Plan around 8:00 AM to 2:00 PM in Prague, which is 12:45 PM to 6:45 PM in Kathmandu, to catch everyone during office hours. Kathmandu is 4.75 hours ahead of Prague, but with 6 hours of common ground you can hold morning or afternoon meetings without anyone working odd hours. Note that Prague follows daylight saving while Kathmandu stays put, so the times above drift by an hour seasonally.
