Calgary is 12.75 hours behind Kathmandu
There is no standard 8-to-6 overlap. Someone joins early or late.
For Kathmandu and Calgary, the standard workday in one city falls outside office hours in the other — that's what 12.75 hours of distance does. Keep live syncs short and infrequent, and let written updates carry the day-to-day between Kathmandu and Calgary. Because only Calgary changes its clocks, the overlap above isn't fixed; expect a one-hour shift when Calgary enters or leaves daylight saving.
