We need your date of birth to calculate your individual biorhythm.

As soon as a human being is weaned from the umbilical cord of the mother, our vegetative nervous system starts its own rhythm. This rhythm is known as the "biorhythm".

However, so that we can analyze and calculate even more precisely, we also need the first name, surname and place of birth.

The sum of these values then results in your rhythm/vibration.
