How to understand it
For a date, add its digits and reduce to a single digit, preserving 11, 22 and 33 as master numbers in selected calculations. For a name, A through I map to 1 through 9 and the pattern repeats; vowels are AEIOU and Y counts as a consonant here.
An example
Two spellings can yield different results, so the chosen name and method belong beside the number. The arithmetic is the fact; the meaning is a reflective interpretation.
Use it carefully
Avoid entering sensitive information you do not wish to use. A result does not diagnose traits or determine compatibility.
Try a reflection
Which part of a number description invites a useful question, even if it does not fit perfectly?
