Calgary is 14 hours behind Shanghai

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

Coordinating Shanghai and Calgary is tricky: 14 hours of separation means their standard hours don't intersect. Async-first is your friend here. Reserve real-time meetings for the rare occasions someone can log on before or after hours. The window above shifts seasonally: Calgary keeps daylight saving while Shanghai ignores it.
