How Numero.Guru Calculates
Every result on Numero.Guru comes from classical, published numerology systems — not black-box guesswork. This page documents the exact systems, letter-value tables and sources our calculation engine implements, and the experts who verify it.
Which numerology systems does Numero.Guru use?
Numero.Guru uses the Chaldean system for name and mobile-number analysis, the Pythagorean system for life path and expression numbers, the classical Lo Shu 3×3 grid for date-of-birth grid analysis, and Vedic Muhurta principles for auspicious date selection. Each tool states which system it applies.
- Chaldean — letters map to 1–8 by sound vibration (9 is held sacred and unassigned). Used for names, brands, mobile and vehicle numbers.
- Pythagorean — letters map A=1…I=9 cyclically. Used for life path, expression, soul urge and personal year numbers.
- Lo Shu Grid — birth-date digits placed on the classical 3×3 magic square, revealing missing and repeated numbers.
- Vedic Muhurta — day-lord and number harmony principles behind the Lucky Date Finder.
