The Babylist Due Date Calculator is a pregnancy tracking tool used to estimate the expected delivery date of a baby. It is commonly based on the first day of the last menstrual period (LMP) or the date of conception.
Pregnancy is typically around 40 weeks (280 days), and this calculator helps expectant parents understand important milestones throughout pregnancy. It is widely used for planning, prenatal care scheduling, and tracking fetal development stages.
While it does not replace medical advice, it provides a helpful estimate for expecting parents and healthcare planning.
