Numerology

Numerology turns a birth date and a name into six core numbers — Life Path, Expression, Soul Urge, Personality, Birthday and Personal Year. Every calculator here shows its working, so you can check the result by hand and disagree with the reading if you want to.

Numerology: Calculators, Core Numbers and What They Mean

Calculators

Full chart calculator Every core number from your name and birth date, with the arithmetic shown. Name numerology Letter by letter, in both the Pythagorean and Chaldean systems. House number What an address reduces to, including addresses with letters. Compatibility How two Life Path numbers interact.

The core numbers

A numerology chart is built from six positions. Each answers a different question.

Life Path The road you keep walking. Calculated from your birth date. Expression What you are built to do. From every letter of your name. Soul Urge What you want privately. From the vowels. Personality How strangers read you. From the consonants. Birthday One specific talent, from the day of the month. Personal Year The theme of the twelve months you are in.

Six positions, six different spreads

How often does each number come up?

It depends on the position. Birth dates give Life Paths 1, 3, 5, 7, 8 and 9 about 11% each, while 2 and 4 lose part of their share to the master numbers 11 and 22. Names behave differently: vowels pile first names onto Soul Urge 6, which covers nearly a quarter of US babies given a top-1,000 name, 23.6%.

The brightest bar in each panel is the most common value. Life Path, Birthday and Personal Year are weighted by US births; the three name numbers use first names only.

Two systems, different answers

Pythagorean numbering runs A=1 through I=9 and repeats. Chaldean assigns values by sound instead of sequence and never uses 9 at all. Feed the same name into both and you get different numbers — which is worth knowing before anyone tells you their result is the correct one.

Compare both tables

Master numbers Why 11, 22 and 33 are never reduced — and what that costs. Karmic debt 13, 14, 16 and 19, and where they hide in a chart. Chaldean system The older table, and why it skips the number nine.

What numerology is, plainly

Numerology assigns numbers to letters and dates, reduces them to single digits, and reads meaning into the result. The Pythagorean version used across the West is attributed to Pythagoras, though the attribution is loose — the system as practiced today was assembled in the early twentieth century.

There is no mechanism by which a birth date could determine character, and no evidence that it does. What numerology offers is a fixed set of prompts: twelve descriptions, applied through a procedure you did not choose, which sometimes surfaces a thought you had been avoiding. That is a reasonable thing to want. It is not a reasonable basis for a medical, legal or financial decision.

Everything on this site shows its arithmetic for that reason. If the reading lands, you can see exactly which sum produced it. If it does not, you have lost nothing but a minute.
