Calgary is 13 hours behind Ho Chi Minh City

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

Ho Chi Minh City and Calgary sit on opposite ends of the clock — a 13-hour gap leaves no common business hours to work with. Lean on recorded updates, shared docs, and clear handoffs so the 13-hour gap doesn't stall progress between meetings. Bear in mind Calgary shifts for daylight saving while Ho Chi Minh City stays fixed — recheck these hours after each clock change.
