Kathmandu is 4.75 hours ahead of Oslo
Best overlap: 8:00 AM to 2:00 PM in Oslo is 12:45 PM to 6:45 PM in Kathmandu.
The sweet spot is 8:00 AM to 2:00 PM Oslo time, matching 12:45 PM to 6:45 PM in Kathmandu. Scheduling is forgiving here: with 6 hours of overlap, a missed slot just means picking another one the same day. Just remember Oslo changes its clocks for daylight saving and Kathmandu doesn't, so confirm the overlap whenever the seasons turn.
