If you are scheduling a call between Ho Chi Minh City and Istanbul, the overlap window is limited to typical business hours. When it is 1 pm in Ho Chi Minh City it is 9 am in Istanbul — a workable window for scheduling. The latest reasonable overlap is around 5 pm in Ho Chi Minh City (1 pm in Istanbul). Outside this window there is effectively no good overlap for regular office hours.
Ho Chi Minh City and Istanbul have a comfortable window for a family call — no awkward alarms required. Ho Chi Minh City is 4 hours ahead of Istanbul, which gives you 4 hours of genuine overlap when both sides are free. Aim for between 6 pm and 10 pm in Ho Chi Minh City — that lands at 2 pm to 6 pm in Istanbul, 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.
