Due Date Calculator
About Due Date Calculation
This calculator helps estimate your due date using different methods. The most common method is based on the first day of your last menstrual period (LMP), which is known as Naegele's rule.
Important Notes:
- Only about 5% of women deliver on their exact due date.
- Most pregnancies last between 37 and 42 weeks.
- Your healthcare provider may adjust the due date based on ultrasound measurements.
- This calculator provides an estimate and should not replace medical advice.
