Best time for family calls

The most manageable option is early evening in Kolkata β around 7 pm β which puts Seoul at 10:30 pm. 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.
