Calculate due date

The expected date of birth is an exciting milestone for parents-to-be. It is the date on which your baby is likely to be born. With our online due date calculator, you can easily and accurately calculate this date based on the first day of your last period and the length of your menstrual cycle.

How the calculation works

Traditionally, pregnancy is considered to be 40 weeks or 280 days from the first day of your last period. This estimate assumes a menstrual cycle of 28 days. However, if your cycle deviates from this norm, this will be taken into account in the calculation.

1. Date of last period: Start by entering the date of the first day of your last menstruation.
2. Length of menstrual cycle: Every woman is unique and not every cycle lasts 28 days. Some women have shorter cycles of 21 days, others have longer cycles of up to 35 days or more. Enter your typical cycle length into the calculator.

Based on this data, the tool calculates the expected date of birth for your baby.

Please note:

• The calculated due date is only an estimate. In fact, only around 4% of babies are born exactly on this predicted date.
• Many factors, including maternal health, diet, lifestyle and genetic factors, can influence the actual due date.
• For close monitoring of your pregnancy and confirmation of your due date, you should visit your gynecologist or midwife regularly.

Conclusion:

With our online due date calculator, you have a practical tool at hand to determine the expected date of birth of your baby. It serves as a guide on the exciting path to parenthood. Nevertheless, it is important to seek regular medical advice and examinations to ensure that your pregnancy progresses as smoothly as possible.
