Best time for work calls
If you are scheduling a call between San José and Istanbul, 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.
Best time for family calls
Scheduling a family call between San José and Istanbul takes a little planning. San José is 9 hours behind Istanbul, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in San José — around 7 pm — which puts Istanbul at 4 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.
