Anchorage is 16 hours behind Ho Chi Minh City
Best overlap: 8:00 AM to 10:00 AM in Ho Chi Minh City is 4:00 PM to 6:00 PM in Anchorage.
For the smoothest call, aim inside 8:00 AM to 10:00 AM in Ho Chi Minh City, i.e. 4:00 PM to 6:00 PM in Anchorage. Overlap is at a premium — roughly 2 hours — so claim 8:00 AM in Ho Chi Minh City (4:00 PM in Anchorage) for recurring calls and keep them on time. Because Anchorage is on the previous day, weekend boundaries can shift; check that neither side is meeting on their day off. Daylight saving complicates things slightly: Anchorage observes it, Ho Chi Minh City doesn't, so the difference flexes by an hour part of the year.
