Best overlap: 8:00 AM to 1:00 PM in Amsterdam is 1:00 PM to 6:00 PM in Ho Chi Minh City.
Keep meetings inside 8:00 AM to 1:00 PM in Amsterdam — that maps to 1:00 PM to 6:00 PM in Ho Chi Minh City. Ho Chi Minh City is 5 hours ahead of Amsterdam, leaving about 5 hours of daily overlap — enough for most meetings if you don't leave them too late in the day. Finally, Amsterdam observes daylight saving and Ho Chi Minh City doesn't, so this window shifts by an hour for part of the year — recheck it each spring and autumn.
