Brasília is 8.75 hours behind Kathmandu
Best overlap: 4:45 PM to 6:45 PM in Kathmandu is 8:00 AM to 10:00 AM in Brasília.
Both offices are open during 4:45 PM to 6:45 PM Kathmandu time, which is 8:00 AM to 10:00 AM in Brasília. Because Brasília is 8.75 hours behind Kathmandu, the shared window is only about 2 hours. A fixed slot at 4:45 PM in Kathmandu (8:00 AM in Brasília) saves a lot of back-and-forth.
