Best time for family calls
Boston and Chicago have a comfortable window for a family call — no awkward alarms required. Boston is 1 hour ahead of Chicago, which gives you 4 hours of genuine overlap when both sides are free. Aim for between 6 pm and 10 pm in Boston — that lands at 5 pm to 9 pm in Chicago, 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.
