How we compute this

◆ The method
Step 01

Reduce the birth date

Sum each component of the full birth date — month, day, year — then reduce to a single digit. Master numbers 11, 22, and 33 are preserved throughout the reduction.

1990-07-14 → (1+9+9+0) + (7) + (1+4) = 19 + 7 + 5 = 31 → 4
Step 02

Map the full name

Convert each letter of the full birth name to a digit using the Pythagorean mapping (A=1, B=2, … I=9, J=1, …). Vowels alone drive the Soul Urge; consonants alone drive the Personality.

A=1 · B=2 · C=3 · D=4 · E=5 · F=6 · G=7 · H=8 · I=9 · J=1 …
Step 03

Hold the masters

Across all five core numbers, 11 / 22 / 33 are never reduced — they carry master-number charge and obligation. The date yields Life Path; the full name yields Expression, Soul Urge, Personality.

11 → 11 / 2 · 22 → 22 / 4 · 33 → 33 / 6

This same date, in other systems
