SU HIJUTSU ／ A date, drawn as numbers
About Su Hijutsu and its method
We publish the arithmetic so every result can be checked.
Our scope
The site uses the Gregorian birth date, sums its digits and retains 11, 22 and 33 during reduction. The nine-cell diagram counts digit frequency. Other schools use different rules.
Written interpretation
After you submit a date, the server sends the calculated numbers to an OpenAI model for a fresh interpretation in the selected language. The model can vary its wording. The numbers themselves are determined by arithmetic.
Use and limits
The text is a reflective reading. It is not a factual assessment of personality, health, relationships or future events.
