Introduction

Knowing your estimated due date is one of the first things expectant mothers want to find out. Doctors use Naegele's rule, which adds 280 days (40 weeks) to the first day of your last menstrual period. This calculator uses that method and also shows trimester dates and current pregnancy week.

Or： Due Date = Conception Date + 266 days (38 weeks)
