Baby’s due day Calculator

Estimate the due date by counting 40 weeks from the LMP

The due date can help your doctor to determine the pregnancy status. It is still normal to give birth up to two weeks before and two weeks after an estimated delivery date. You can even choose your child’s birth date as long as your child is healthy. Most pregnancies last around 40 weeks (or 38 weeks from conception), so you can estimate your due date by counting 40 weeks (280 days), from the first day of your last menstrual period (LMP). It can also be calculated by subtracting three months and adding seven days to the LMP. For example, the LMP = 22 July, - 3 months and + 7 days, the due date = 29 April.
