Best time for work calls
If you are scheduling a call between Kolkata and Chicago, 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 Kolkata and Chicago takes a little planning. Kolkata is 10.5 hours ahead of Chicago, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in Kolkata β around 7 pm β which puts Chicago at 8:30 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.
