Conception Date Calculator

(Reverse Due Date Calculator)

Fill in your pregnancy Due Date








The Pregnancy Conception Calculator can help to find out the pregnancy conception date based on the pregnancy due date. The pregnancy conception day is the day when your baby is conceived.

Please remember that your due date is only an estimate. On average only 5% of births take place exactly on the estimated due date. Most are born within a week either side of the estimated due date.
