Calgary is 11.5 hours behind Colombo

There is no standard 8-to-6 overlap. Someone joins early or late.

Don't expect an easy slot here: Colombo and Calgary are 11.5 hours apart, with no overlap across conventional business hours. A shared overlap of zero doesn't mean zero collaboration; it just means leaning harder on documentation and clear ownership. Note the seasonal wrinkle: when Calgary is on daylight saving and Colombo isn't, the gap between them grows or shrinks by an hour.
