Pregnancy Due Date Calculator

Wondering when your baby might arrive? This simple pregnancy calculator estimates your due date based on either the first day of your last menstrual period or your conception date (if you know it).

How It Works

By entering a few key details below, you’ll get an estimated due date, along with your current week of pregnancy.

Option 1: Enter the first day of your last menstrual cycle — this is the most common and reliable method.
Option 2: If you’re certain about your conception date (the day of ovulation or fertilization), select that option for a more personalized result.
