How Does the Pregnancy Due Date Calculator Work?

This calculator is based on Naegele’s Rule, a medically accepted method used by gynecologists during early pregnancy.

It calculates your estimated due date by:

• Taking the first day of your last menstrual period (LMP)

• Adding 280 days (40 weeks) to it

This is the same formula doctors use before early ultrasound confirmation.

Is the Calculated Due Date Accurate?

The calculated due date is an estimate, not a fixed promise.

In reality:

• Only about 5% of babies are born exactly on their due date

Your actual delivery date may vary depending on:

• Ovulation timing

• Menstrual cycle length

• Early ultrasound results

• Overall maternal health

Doctors often adjust the due date after the first ultrasound scan.

Why Knowing Your Due Date Is Important

Understanding your expected delivery date helps you:

• Track your baby’s development week by week

• Plan prenatal doctor appointments

• Prepare emotionally and physically
