Chaldean numerology is the oldest known letter-number system, traced to ancient Babylon (modern Iraq) more than 2,500 years ago. Unlike Pythagorean numerology, which follows alphabetical order, the Chaldean system assigns each letter a value from 1 to 8 based on its sound vibration and treats 9 as sacred, so 9 never sits on a letter and appears only as a calculated result. Chaldean readings work with two numbers: the single root digit and the two-digit compound number, whose symbolic meanings (10 to 52) were popularised by the numerologist Cheiro. The tools below cover the Chaldean name number, soul urge and personality numbers, compound number meanings, psychic and destiny numbers, a lucky-name compatibility check, and business name analysis.

Chaldean Numerology - Frequently Asked Questions
How is Chaldean numerology different from Pythagorean?
Pythagorean numerology assigns letters to numbers 1 to 9 in alphabetical order. Chaldean assigns values 1 to 8 by the sound vibration of each letter and never assigns 9 to a letter, because 9 is held sacred. As a result the same name often produces a different number in each system, and many people find the Chaldean reading more telling for names.
What is a Chaldean compound number?
Besides the single root digit, Chaldean numerology reads a two-digit compound number that carries a deeper symbolic message. The meanings of the compound numbers from 10 to 52, each with a traditional name such as the Royal Star of the Lion (23) or the Star of the Magi (17), were popularised by the numerologist Cheiro.
What are the psychic and destiny numbers?
The psychic (or birth) number comes from the day of the month you were born and shows how you see yourself, especially in early life. The destiny number comes from your full date of birth and shows the path you grow into. The lucky-name check compares your name number against both.
