Pythagorean

Letters → 1‑9 in cycles (a=1 … i=9, j=1 …)

• The Pythagorean method was developed by Pythagoras, a Greek mathematician and metaphysician of the 6th century BC.
• Values run from 1 to 9: numbers are assigned in sequence (A=1, B=2, C=3…) and cycle back to 1.
• It is the easiest, best-known system and the one most widely used by modern numerologists; it is also called Western or Modern numerology.
• It only works with single-digit numbers.
• Beyond self-knowledge, it is used to gain insight into other people: which types are most compatible with you, and why.

Chaldean

Babylonian system: values 1‑8 by vibration

• It is perhaps the oldest known numerology system, with its origin in ancient Babylon.
• Every letter has a value from 1 to 8.
• No letter is assigned the number 9: nine was considered sacred, and attaching it to a letter a great dishonesty.
• Letters and numbers are matched by sound and tone: the key is the vibration between the two.
• Being the older of the two major systems, it is also considered the more “accurate” one.
• It uses the name you are best known by: if your name is Peter Smith but you go by Pete, your chart is calculated on “Pete Smith”.
• It works with compound numbers: single digits represent outer influences, double digits the person's inner aspects.
• Your birth number is the day of the month you were born (May 21st → 21) — the one constant in your chart: it never changes.
