A due date calculator estimates when your baby will be born. It's a tool based on science, not guesswork. Most calculators use either: The first day of your last menstrual period LMP , or The date of conception if known Based on these, the tool calculates your EDD by adding 280 days 40 weeks , the average length of human pregnancy. Those using IVF can also calculate their due date using their IVF transfer date . A due date calculator works by using the day of your last menstrual cycle and the average cycle length to estimate when your baby may arrive. In a typical pregnancy, the expected due date is around 40 weeks , though some pregnancies may continue up to 42 weeks . This calculation helps parents and healthcare providers track pregnancy milestones and monitor fetal growth throughout each stage. For pregnancies involving fertilisation treatments such as IVF, the due date may be based on the embryo transfer date rather than the last period. In these cases, the age of the embryo at transfer is used to determine gestational age and estimate the expected delivery date more accurately. Why Is Knowing Your EDD So Important?
