Formula & Mathematical Methodology: Digit Reduction Method

Personal year = reduce(birth month + birth day + target-year digits)
personal month = reduce(personal year + target month).
Personal year = reduce(birth month + birth day + target-year digits); personal month = reduce(personal year + target month).
  • n: The digit sum being reduced
  • M: A master number (11, 22, or 33) retained by the chosen convention

Rounding: Integer digit sums are shown without rounding.

Worked Example: Date of birth: June 15, 1995; October 2026

Use the default inputs to see each reduction step.

  1. Add birth month, birth day, and the target-year digits.
  2. Reduce the sum to a single digit or retained master number.
  3. Add the target month and reduce again for the personal month.
Result: Different numerology traditions use different mappings and reduction rules; this page names the selected convention.

  • Calendar Month: The month used for the personal-month calculation.

What the calculation includes
