What this tool does
This calculator converts each letter of a name to its Pythagorean value, sums them, and reduces to an expression number from 1 to 9 or a master number.
In Pythagorean numerology every letter carries a number from 1 to 9. Your full name sums to an expression number: the talents your name spells out.

Common questions
Do I need my birth time?
No. Name numerology converts letters to numbers - neither your birth date nor time enters the expression number at all.
Which name should I enter?
Traditions differ: the full birth-certificate name gives the classical expression number, while the name you actually use daily shows the energy you currently broadcast. Comparing both is often revealing.
What about the vowels-only number?
Summing only the vowels gives the soul urge number, and only the consonants gives the personality number. This tool computes the full expression number from every letter.
Do accents and hyphens count?
The Pythagorean chart uses the 26 base letters, so accents, spaces, and punctuation are ignored in the calculation.
