How is the Due Date Calculated?
For most pregnancies, the estimated due date is calculated by adding 280 days (40 weeks) to the first day of your Last Menstrual Period (LMP), assuming a standard 28-day cycle.
Disclaimer: This calculator provides an estimate. Only about 5% of babies are born on their exact due date. Please consult with your healthcare provider for medical advice.
