Pregnancy due date calculator
As long as you have periods on a regular cycle of every 28 days, we calculate your due date as nine months and seven days from the first day of your last period. It can be really confusing to work out, so that’s where our pregnancy due date calculator comes in handy!

Calculate your baby's due date
Our pregnancy due date calculator does all the maths for you! It gives you a useful guide to when your baby’s likely to be born, but remember; the majority of babies are late and only around 5 or 6 percent of women give birth on their due date.
Please enter the first day of your last period
