In short

Calculate the Pythagorean numerology of your name: expression number, soul urge, personality number and balance, with full interpretations.

  • Nicknames matter. Read the name you are actually called by for how you are perceived day to day.
  • Y is a vowel when it carries the vowel sound and a consonant when it does not.
  • Married or changed names are read as a second layer over the birth name, not a replacement.
  • A soul urge that clashes with the expression number usually explains why a comfortable life can still feel wrong.

Assigning number values to letters is an ancient practice: Hebrew gematria, Greek isopsephy and Arabic abjad all predate the common era, and all were used for interpretation as well as encoding. Modern name numerology uses a Pythagorean grid mapping A through I to one through nine and repeating.

The Chaldean alternative assigns different values and omits nine as sacred. Both circulate; the Pythagorean system is the standard in English-language practice and is what is used here.
