The due date calculator

A great tool

The due date calculator gives you an estimate of when your baby is expected to be born. It can show you the centre of the birth period. Every pregnancy is unique and therefore your baby's actual due date may differ by days or even weeks from this calculated due date.

It is also possible that the due date will be postponed again. This happens if the examinations show that your baby is slightly further or less developed than you calculated.

Becoming a mum is exciting and scary at the same time. But with a calculated due date and regular check-ups, you can be sure that you are doing everything right and that your baby is in the best hands.

What is a due date calculator?

A due date calculator is an online tool that pregnant women can use to calculate the expected due date of their child. The calculator is usually based on the date of the last period and the average length of the menstrual cycle.

How does a due date calculator work?

A due date calculator uses the date of the last period to calculate the expected due date. The calculator also takes into account the average length of the menstrual cycle to provide a more accurate estimate. Some due date calculators also offer the option of calculating the week of pregnancy and tracking important milestones during pregnancy.

Why is a due date calculator important?

A due date calculator is important because it gives mums-to-be an estimate of when their baby is likely to be born. This helps them prepare for the arrival of their child and make important decisions, such as choosing where to give birth, planning maternity leave and organising childcare.

How accurate is a due date calculator?

A due date calculator can provide a fairly accurate estimate of the expected date of birth, but it's important to note that every pregnancy is unique. In fact, only about 4% of babies are born on that exact day. Most babies, 95.5%, are born in the four weeks around this calculated date, i.e. two weeks before or two weeks after.
All in all, a due date calculator is an extremely useful tool for expectant mothers to provide orientation and help them organise their pregnancy.
