Chaldean Numerology
An older system, listening for the vibration in each letter sounded aloud.
The Chaldean system is the oldest known numerology method, originating in ancient Babylon. Unlike Pythagorean numerology, it assigns letters based on sound vibration rather than alphabetical order — and the number 9 is considered sacred, never assigned to any letter.
Because the Chaldean letter chart maps differently, the same name often produces different numbers than the Pythagorean system. Many practitioners consider Chaldean numbers to reveal the deeper, hidden vibrations of a name — the energy operating beneath the surface. This page calculates all your name-based numbers using the Chaldean system and compares them side by side with their Pythagorean counterparts.
Chaldean numerology traditionally uses the name you are commonly known by, rather than your full birth name. You can enter either.

Chaldean numerology assigns letters to numbers 1-8 (9 is sacred and unassigned) based on sound vibrations rather than alphabetical order. This produces different name numbers than the Pythagorean system and often reveals hidden aspects of your personality.
