Best time for work calls
If you are scheduling a call between Chicago and Boston, the overlap window is limited to typical business hours. When it is 9 am in Chicago it is 10 am in Boston — a workable window for scheduling. The latest reasonable overlap is around 4 pm in Chicago (5 pm in Boston). Outside this window there is effectively no good overlap for regular office hours.
Best time for family calls
Chicago and Boston have a comfortable window for a family call — no awkward alarms required. Chicago is 1 hour behind Boston, which gives you 2 hours of genuine overlap when both sides are free. Aim for between 6 pm and 8 pm in Chicago — that lands at 7 pm to 9 pm in Boston, 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.
