Numerology — Pythagorean and Chaldean, with the working shown

Scores a name under both letter tables and works a life path from a birth date by both of the usual methods, printing every step. A Korean name gets its own panel: neither table has a value for 김, so the number depends on which romanisation you pick, and the tool shows the common spellings side by side.

Two letter tables and a birth date, with every step of the arithmetic printed. Numerology is the one tradition in this corner whose computation you can check in your head, which is why the page shows all of it and attributes the interpretation instead of asserting it.

For fun

This is entertainment. The arithmetic is exact and you can check every step of it; what a number is supposed to say about a person is folklore from around 1900, and there is nothing behind it.

Letter table

A–I is 1–9, J–R is 1–9 again, S–Z is 1–8. The modern Western default, from writers of the 1900s–1920s. Nothing to do with Pythagoras.

The two methods agree.

Sources

  • The Pythagorean table as popularised by L. Dow Balliett (1900s) and Juno Jordan (1920s); the Chaldean table as it is universally printed. Neither is ancient, and the names of both are marketing.
  • Accent folding follows the Spanish charts (Ñ as N, tildes ignored — numato.pl, significadodelosnumeros.com) and the French ones (É/È/Ê as E, Ç as C — dcode.fr).
  • The romanisations come from this site’s own Revised Romanisation module, with the common passport spellings listed beside it.

How to use it

  1. Pick a table, and know that they disagree

    Pythagorean numbers A–Z straight through; Chaldean groups them differently and has no 9 at all. The same name gets different numbers under the two, so a page that gives you one number without naming its table has told you nothing you could check.

  2. Set the Y switch yourself

    Whether Y counts as a vowel changes the soul-urge number and leaves the expression number alone. The sources genuinely disagree and there is no authority to settle it, so the choice is yours and the page records which way you set it.

  3. Read the two life paths together

    One method reduces the year, month and day separately and adds; the other adds every digit at once. They can never disagree about the final single digit — digit sums preserve a number modulo nine — so the only thing they can differ about is whether an 11, 22 or 33 surfaced on the way. That is the whole of the argument practitioners have about it.

Common questions

What number does a Korean name have?

None, until you spell it in Latin letters. Both tables are tables of A–Z, invented by English-speaking writers around 1900; 김 is not in either. So the tool romanises and then shows you the common passport spellings — Kim and Gim, Lee and Yi and Rhee — with the different numbers they produce. That is not a limitation of the tool; it is what this arithmetic is measuring.

Is any of this Pythagoras or Chaldean?

No. Both names are marketing. The "Pythagorean" table was popularised by L. Dow Balliett in the 1900s and Juno Jordan in the 1920s; the "Chaldean" table has no demonstrated connection to Chaldea. Neither is ancient, and the page says so where the name appears.
