Pythagorean numerology (fun only).
Life-path number is calculated by summing all digits of a birthdate (or numeric letter values of a name) and reducing to a single digit.
Entertainment/tradition — no scientific basis.
Like the zodiac tool, this reflects a long-standing cultural tradition rather than anything empirically tested — the appeal is more about reflection and pattern-finding than prediction.
'Ada Lovelace' → life-path 9.
This uses Pythagorean (Western) letter values 1–9. Chaldean systems use different mappings.
11, 22, and 33 are traditionally kept un-reduced. This tool reduces to a single digit by default.
No — like astrology, it's a cultural and symbolic tradition rather than an evidence-based system, and this tool is offered purely for entertainment.
