Numerology calculator
Life path from a date, and the name number in both the Pythagorean and Chaldean systems — because they disagree, and most calculators pick one without telling you.
The sums
Life path
Add every digit of the date of birth, then reduce. 15 June 1990 is 1+9+9+0+0+6+1+5 = 31, and 3+1 = 4. The calculator shows both this and the variant where day, month and year are reduced separately first — they usually agree, and where they do not, you can see it rather than wonder.
Master numbers
11, 22 and 33 are conventionally left unreduced. That is a convention rather than arithmetic, so every reduction step is printed — a practitioner who reduces them anyway can read the number underneath.
Two systems that disagree
Pythagorean runs 1 to 9 straight down the alphabet in blocks. Chaldean uses an older assignment with no 9 at all — nine was held apart. The same name routinely comes out differently, and when it does, this page says so instead of quietly choosing.

Soul urge and personality
The vowels of a name taken alone give the soul urge number; the consonants give the personality number. Both are shown, on the Pythagorean values.
