Kathmandu is 10.75 hours ahead of Ottawa
There is no standard 8-to-6 overlap. Someone joins early or late.
Set against a 10.75-hour difference, Ottawa and Kathmandu run their workdays on completely separate schedules. Block a single recurring off-hours slot that both teams agree on, rather than negotiating a new awkward time every week. Seasonal note: Ottawa uses daylight saving and Kathmandu doesn't, so double-check the times in your own months — they can move by an hour.
