How is the due date calculated?
Pregnancy due dates are estimated based on the first day of your last menstrual period (LMP) and the average cycle length. Using Naegele's rule, our calculator adds 280 days (40 weeks) to that date, adjusted for your personal cycle duration. While most pregnancies last about 40 weeks, remember that this is only an estimate—only about 4% of babies are born exactly on their due date!
