Pregnancy Due Date Calculator
Our pregnancy calculator is very easy to use. Simply select the date of the first day of your last period to start calculating your due-date.
Pregnancy normally lasts around 40 weeks from the first day of your last menstrual period. Confused already? Forget complicated charts - try our handy due date calculator to help you work out when you can expect your baby to arrive.
If you are recently pregnant and wondering ‘when is my due date?’ Just enter the first day of your last period and our pregnancy calculator will estimate your baby’s due date. Some women have menstrual cycles that are not exactly 28 days though, so if your cycle is longer or shorter than 28 days, please adjust the number as required.
Pregnancy Week Calculator
Want to know which week of pregnancy you are in? Our pregnancy calculator will do that too. Follow the prompts for due date calculation and we’ll also let you know the approximate week of your pregnancy.
Please remember that the pregnancy calculator just gives an estimate and that the majority of women do not give birth on their due date.
