Calculations and methodology

Numerology relies on simple, stable and individual data — your date of birth, all your first names and your birth surname.

Data used

A numerological study uses only objective biographical data: date of birth, every first name and the birth surname. No preliminary questionnaire is needed — the numbers themselves contain abundant information.

The detail of the calculations is provided in Lydie Castells' publications. Calculations are performed and then interpreted through the symbolism of numbers.
