Understanding Your Due Date

Your due date, also known as the estimated date of delivery (EDD), is calculated as 40 weeks from the first day of your last menstrual period. This prediction helps you and your healthcare provider plan for your baby's arrival, though only about 4% of babies are born exactly on their due date.
