LP = \text{DigitSum}(Y) + \text{DigitSum}(M) + \text{DigitSum}(D) \pmod 9Each date reduces to base digits 1–9 or master numbers (11, 22). Harmony scores evaluate elemental resonance (Fire/Air/Water/Earth) and complementary numerical triads.
Worked Example
Scenario: Person 1 born March 12, 1994 (Life Path 2) and Person 2 born November 28, 1995 (Life Path 9).
Person 1: 3 + 12 + 1994 -> 3 + 3 + 23(5) = 11 / 2 (The Peacemaker).
Person 2: 11 + 28 + 1995 -> 11 + 10(1) + 24(6) = 18 -> 9 (The Humanitarian).
2 and 9 form a deeply compassionate, mutually supportive spiritual partnership.
