Kathmandu is 8.75 hours ahead of Santiago
Best overlap: 8:00 AM to 10:00 AM in Santiago is 4:45 PM to 6:45 PM in Kathmandu.
If you set up a recurring sync, 8:00 AM to 10:00 AM in Santiago (4:45 PM to 6:45 PM in Kathmandu) is the natural home for it. Kathmandu is 8.75 hours ahead of Santiago, so you only get about 2 hours of overlap a day — worth locking in a standing time like 8:00 AM in Santiago (4:45 PM in Kathmandu) before it slips. Keep an eye on the calendar — Santiago observes daylight saving and Kathmandu doesn't, which nudges this window by an hour twice a year.
