If you are scheduling a call between San José and Seoul, there is very limited or no overlap in normal business hours. Consider early-morning or late-evening calls for one side, or use async communication.
San José and Seoul have a comfortable window for a family call — no awkward alarms required. San José is 15 hours behind Seoul, which gives you 4 hours of genuine overlap when both sides are free. Aim for between 6 pm and 10 pm in San José — that lands at 9 am to 1 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.
