Pregnancy Calculator – Know Your Baby’s Due Date

Pregnancy is an exciting journey, and knowing your baby’s due date helps you plan for each stage. Our Pregnancy Calculator is a simple and free tool that allows you to calculate your expected delivery date based on your last menstrual period (LMP) or conception date.

How the Pregnancy Calculator Works

Our pregnancy calculator uses a standard formula:

  • Step 1: Enter the first day of your last menstrual period (LMP).
  • Step 2: Or, if you know it, enter the conception date.
  • Step 3: Click “Calculate” to see your estimated due date.

Most pregnancies last about 40 weeks, and our tool considers this to give you an accurate prediction.
