Mulank numerology, explained
Mulank numerology reduces your birth date to a set of single-digit numbers — 1 through 9 — each mapped to a Major Arcana tarot archetype. Unlike sun-sign astrology, it doesn't need your birth time or location, just the date. This guide walks through exactly how each number is calculated, with worked examples, so you can check the math yourself or just understand what AstroFree's free Mulank calculator is doing behind the scenes.
