If you are scheduling a call between Helsinki and Seoul, the overlap window is limited to typical business hours. When it is 9 am in Helsinki it is 3 pm in Seoul — a workable window for scheduling. The latest reasonable overlap is around 11 am in Helsinki (5 pm in Seoul). Outside this window there is effectively no good overlap for regular office hours.
Scheduling a family call between Helsinki and Seoul takes a little planning. Helsinki is 6 hours behind Seoul, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in Helsinki — around 7 pm — which puts Seoul at 1 am. Someone will need to stretch a little, but at least no one's setting a middle-of-the-night alarm. Weekends tend to give the most flexibility if you can agree on a time in advance.
