Pregnancy Due Date Calculator — Overview

A Pregnancy Due Date Calculator estimates the expected date of delivery for a pregnant woman. It is one of the first and most exciting calculations for expectant parents.

How is it calculated?

The most common method is Naegele's rule, which is used by this calculator. It works by taking the first day of your last menstrual period (LMP), adding one year, subtracting three months, and adding seven days.

Frequently Asked Questions

The due date is only an estimate. Only about 5% of babies are born on their exact due date. A normal pregnancy can last anywhere between 38 and 42 weeks.

If your menstrual cycles are irregular, a due date calculated based on your LMP might be less accurate. An early ultrasound is often a more precise method for dating the pregnancy in such cases.
