What is the difference between Chaldean and Pythagorean numerology?

The letter table. Pythagorean assigns 1 to 9 in alphabetical blocks; Chaldean assigns 1 to 8 based on the vibration each sound was believed to carry, and reserves 9 as sacred so no letter receives it. The two systems will often give you different numbers for the same name, and neither is a miscalculation of the other.

Why is there no 9 in the Chaldean system?

The tradition treats 9 as sacred — the number of completion — and holds it apart from the alphabet. It can still appear as a final result once the compound number is reduced; it simply is never the value of a letter.

What is a compound number?

The total of your letters before it is reduced to a single digit. Chaldean numerology reads it as the outer influence around a name, while the reduced root describes the inner character. A 37 and a 46 both reduce to 1, but the tradition reads them very differently.

Which name should I enter?

The name you are actually known by, day to day. This is the clearest difference in practice: Pythagorean numerology reads the full birth name, while Chaldean reads the name in current use — the one being spoken aloud.

Are these readings predictions?

No. They are the traditional interpretations recorded for each compound number, presented as what the system says rather than as claims about what will happen.
