Calculating the due date and week of pregnancy (calculator)

Calculator, calculating the term: date of birth and week of pregnancy?

Calculating the most accurate date of birth is problematic. It is impossible to determine 9 months in advance the specific day when your baby will come into the world.

Why is it impossible to calculate the exact date of birth?

This may be because you do not know the exact time of fertilization. Even if you know the exact time of fertilization, many factors affect pregnancy and fetal growth.

The exact date of delivery is also hampered by the length of the menstrual cycle, irregular menstruation and various hormonal variations.

The gynaecologist will determine a more accurate term and date of delivery on the basis of a sonographic examination. The date of delivery is adjusted several times during the pregnancy based on the findings.

The calculator will serve you well in calculating the approximate date of delivery. It may differ from the actual date of delivery by up to 2 weeks.

As an added bonus, the calculator will calculate the approximate week of pregnancy. From this you can derive the number of days remaining until delivery.

But...

Physiological labour takes place between the 38th and 42nd week of pregnancy.
