About This Calculator
This calculator uses Naegele's rule, which adds 280 days (40 weeks) to the first day of your last menstrual period. Only 4-5% of babies are born on their exact due date. Most are born within 2 weeks before or after. Your healthcare provider may adjust your due date based on ultrasound measurements.
