Frequently Asked Questions

Everything you need to know about our calculators

What is the difference between Pythagorean and Chaldean numerology?

The Pythagorean system uses the numbers 1 through 9 to map letters. It is the most common Western framework. The Chaldean system, developed in ancient Babylon, is based on sound vibrations and uses numbers 1 through 8. In the Chaldean system, the number 9 is considered sacred and is excluded from calculations except when it represents the final sum.
