What is computational due date calculation?

Pregnancy care has advanced tremendously in the last 200 years, but most due date calculators are based on a simple formula called Naegele's Rule popularized in 1812. The simple formula does not take into account that the length of pregnancy changes based on the mother's and baby's characteristics. In addition, there is no one normal length of pregnancy, but a range of healthy pregnancy lengths. By just providing a single number, the forumula makes it seem like a baby should be born on a certain day which can cause confusion and increase anxiety for the mother.

Computational due date calculation does not rely on a simple formula. Instead, it uses powerful computer algorithms to match your pregnancy to over 11 million births to find similar pregnancies. Based on those similar pregnancies, it can provide accurate, personal, and meaningful estimates of when your baby will be born.
