How is a Pregnancy Due Date Calculated?

A pregnancy typically lasts around 40 weeks (280 days) from the first day of your last menstrual period (LMP). This calculator helps you estimate your due date based on either your LMP or the date of conception.

Methods of Calculation:

  • Last Menstrual Period (LMP): Adds 280 days (40 weeks) to the first day of your last period.
  • Conception Date: Adds 266 days (38 weeks) to the estimated date of conception.

While this calculator provides an estimate, your actual due date may vary. Ultrasound examinations and consultations with healthcare professionals provide more accurate estimations.

Important Note: Every pregnancy is unique, and this tool is for informational purposes only. Always consult your doctor or midwife for professional advice regarding your pregnancy.
