The data used
Numerology relies on simple data based on the date of birth, all first names and the birth surname: stable, individual elements that make each person unique in society.
If you have changed your name or first name, or if you have dual nationality or two dates of birth (the real date and the declared one), we invite you to watch this short video (6 min) which explains which data to use in every possible situation.
No preliminary questioning is needed to access the elements that define you. The numbers alone are a wealth of information.
Calculations and interpretation
Carrying out a numerological study means performing various calculations and then, thanks to the symbolism of numbers, interpreting the results obtained.
The detail of the calculations is provided in Lydie Castells' publications.
Two ways to calculate
If you want to save time and avoid mistakes, two simple options are available to you: the Personal Tree (free) and the NumStrat tool.
The Personal Tree is a free tool that saves you time and prevents calculation errors.
NumStrat is an automated calculation tool (paid) that performs the numerological calculations for you and avoids any error.
