Kathmandu is 4.75 hours ahead of Copenhagen
Best overlap: 8:00 AM to 2:00 PM in Copenhagen is 12:45 PM to 6:45 PM in Kathmandu.
Plan around 8:00 AM to 2:00 PM in Copenhagen, which is 12:45 PM to 6:45 PM in Kathmandu, to catch everyone during office hours. That's a roomy 6 hours of common time each day, so finding a slot that suits everyone is rarely a problem. Note that Copenhagen follows daylight saving while Kathmandu stays put, so the times above drift by an hour seasonally.
