Kathmandu is 2.75 hours ahead of Nairobi
Best overlap: 8:00 AM to 4:00 PM in Nairobi is 10:45 AM to 6:45 PM in Kathmandu.
Plan around 8:00 AM to 4:00 PM in Nairobi, which is 10:45 AM to 6:45 PM in Kathmandu, to catch everyone during office hours. Kathmandu is 2.75 hours ahead of Nairobi, but you'd hardly notice — 8 hours of shared hours makes this feel like working in neighbouring time zones.
