Copenhagen is 5 hours behind Ho Chi Minh City
Best overlap: 1:00 PM to 6:00 PM in Ho Chi Minh City is 8:00 AM to 1:00 PM in Copenhagen.
If you set up a recurring sync, 1:00 PM to 6:00 PM in Ho Chi Minh City (8:00 AM to 1:00 PM in Copenhagen) is the natural home for it. Copenhagen is 5 hours behind Ho Chi Minh City, leaving about 5 hours of daily overlap — enough for most meetings if you don't leave them too late in the day. Because Copenhagen and Ho Chi Minh City don't both observe daylight saving, plan to re-check the overlap around March and November.
