# Name Numerology Calculator (Chaldean and Pythagorean)

Score a name letter by letter in both systems, returning the Expression, Soul Urge, Personality and Naamank values, the Chaldean compound number with its classical reading, and any karmic debt in the total.

Accepts names in Devanagari, Bengali, Tamil, Telugu, Gujarati, Kannada, Malayalam, Gurmukhi and Odia; POST to /numerology/transliterate first for a Latin suggestion. The authoritative spelling is the one the person actually writes, so the transliteration is a suggestion and not an answer.

## Inputs

- **birth_date** — date of birth (`YYYY-MM-DD`). **No time, place or timezone required.**
- **name_at_birth** *(optional)* — full name as given at birth, in Latin letters.
  Drives Expression, Soul Urge and Personality.
- **name_in_use** *(optional)* — the name used day to day. Drives the Naamank.
- **system** *(optional)* — `pythagorean`, `chaldean` or `both` (default `both`).
- **y_mode** *(optional)* — `heuristic` (default), `vowel` or `consonant`. Controls
  whether Y counts as a vowel, which moves Soul Urge and Personality but never Expression.
