Chaldean Numerology
An ancient numerological system originating in Babylon — assigns different letter values than Pythagorean and is considered by many practitioners to be the older and more spiritually precise system.
Chaldean Numerology is believed to originate in ancient Babylon (Chaldea) and predates the Pythagorean system. Unlike Pythagorean Numerology, which assigns letters values sequentially, Chaldean assigns values based on the vibrational frequency of each sound.
The key differences from Pythagorean: the number 9 is considered sacred in Chaldean and is not assigned to any letter; the values run 1–8 for letters. Chaldean also treats some two-digit "compound numbers" as meaningful in their own right rather than always reducing to single digits.
Chaldean is considered by many numerologists to be more subtle and precise for name readings, while Pythagorean is more widely used and more accessible. Most contemporary Western practitioners use Pythagorean; practitioners in India and the Middle East more often use Chaldean or its regional variants.
