Ho Chi Minh City is 11 hours ahead of Philadelphia

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

Philadelphia and Ho Chi Minh City sit on opposite ends of the clock — an 11-hour gap leaves no common business hours to work with. Lean on recorded updates, shared docs, and clear handoffs so the 11-hour gap doesn't stall progress between meetings. Bear in mind Philadelphia shifts for daylight saving while Ho Chi Minh City stays fixed — recheck these hours after each clock change.
