About the Pregnancy Calculator

This calculator estimates your due date based on different calculation methods:

Last Menstrual Period (LMP): Adds 280 days (40 weeks) to the first day of your last period
Conception Date: Adds 266 days (38 weeks) to the conception date
Ultrasound Date: Calculates based on gestational age at the time of ultrasound

Understanding Your Results:

The due date is an estimate – only about 5% of women deliver on their exact due date. Most babies are born within two weeks before or after the estimated date.
