Due date calculator

Use the calculator to figure out your baby's due date. Fill in the fields in the top 2 rows, hit "Calculate!" and the information in the bottom 3 rows will fill in automatically. When you go to your doctor for prenatal care, they will also confirm your due date. Their calculation may be a few days different than yours. But this will give you a good idea of when to expect your new baby.
