How this works
Only the calendar day is reduced: for example, 29 → 2 + 9 → 11 → 1 + 1 → 2. This follows the existing birth-number engine.
Numerology is a traditional interpretation, not a probability or proof of future events. Missing digits do not diagnose health, character or destiny.
Destiny uses the existing full-date digit-sum method, retaining master numbers 11, 22 and 33. Mulank reduces the day of birth to one digit.
