Kathmandu is 2.25 hours behind Beijing
Best overlap: 11:00 AM to 6:00 PM in Beijing is 8:45 AM to 3:45 PM in Kathmandu.
Plan around 11:00 AM to 6:00 PM in Beijing, which is 8:45 AM to 3:45 PM in Kathmandu, to catch everyone during office hours. Kathmandu is 2.25 hours behind Beijing, but with 7 hours of common ground you can hold morning or afternoon meetings without anyone working odd hours.
