Due date calendar

Working out when your baby is due can get pretty complicated. Why not let us do the maths and work out your estimated due date for you.

 

Bear in mind that most women give birth within a two week period around their due date rather than on their actual due date, so don’t be too disappointed if your due date comes and goes!



How to use the due date calendar
Simply enter the first day of your last monthly period and how many days your cycle usually lasts in the box below. Our calculator will then calculate your due date for you.
