Wondering when your baby will arrive? Use our free due date calculator to estimate your baby's expected date of birth based on the first day of your last menstrual period (LMP). Quick, simple, and medically trusted.
This calculator uses the standard method of adding 280 days (40 weeks) to the first day of your last period to estimate your due date. Most healthcare providers use this method because it’s simple and reliable for women with regular menstrual cycles.
Knowing your estimated due date helps you and your doctor plan your prenatal care, track your baby's growth, and prepare for delivery. Remember, this is only an estimate — every pregnancy is unique, and only about 5% of babies are born exactly on their due date!
This calculator provides an estimate only and should not replace medical advice. Always consult your healthcare provider for accurate pregnancy tracking, prenatal care, and birth planning.
