How accurate is the due date?

Only about 5% of babies are born on the exact EDD (Expected Date of Delivery) given to them. This date is an estimate based on an average 40 week pregnancy. The most accurate way to determine the date is the ultrasound scan done at 12 weeks.

How to calculate the due date of the baby?

According to Naegele's rule: Counting back 3 months from the date of the last menstrual period (LMP), adding 7 days and a year. Or: LMP + 280 days.
