If you are scheduling a call between Ho Chi Minh City and Seoul, the overlap window is limited to typical business hours. When it is 9 am in Ho Chi Minh City it is 11 am in Seoul — a workable window for scheduling. The latest reasonable overlap is around 3 pm in Ho Chi Minh City (5 pm in Seoul). Outside this window there is effectively no good overlap for regular office hours.
Ho Chi Minh City and Seoul have a comfortable window for a family call — no awkward alarms required. Ho Chi Minh City is 2 hours behind Seoul, which gives you about an hour of genuine overlap when both sides are free. Aim for between 6 pm and 7 pm in Ho Chi Minh City — that lands at 8 pm to 9 pm in Seoul, after the school run and before anyone's ready for bed. For a Sunday catch-up or a midweek check-in, this is the sweet spot.
