Pythagorean Numerology

Pythagorean numerology is one of the most popular numerology systems. In this Pythagorean numerology method, it turns the letters of your name and the digits of your date of birth into numbers from 1 to 9 by using an A-to-Z chart. This system helps you learn about your life direction, destiny, personality, and more. Read on to learn how you can calculate your number, the history of Pythagorean numerology, the name numerology Pythagorean chart, and more.

What Is Pythagorean Numerology?

Pythagorean numerology is a system that changes the letters of your name and the digits of your date of birth into numbers from 1 to 9, and each number shows personality traits, strengths, weaknesses and life direction.

This method is named after the ancient Greek philosopher Pythagoras, and this method works with two inputs, which include your full birth name and your full date of birth, and it uses five core numbers, which are the Life Path Number, Expression Number, Soul Urge Number, Personality Number and Birthday Number. The Life Path Number comes from the date of birth, while the Expression, Soul Urge and Personality Numbers are calculated from the name, and the Birthday Number comes from the day of birth.

Then every total is added again and again until it becomes a single digit, which is between 1 and 9. The only exceptions are 11, 22 and 33, which are called master numbers, and these numbers are usually kept as they are because they are believed to carry a higher potential. Each single digit is then read for its meaning, such as leadership for 1, sensitivity for 2 or creativity for 3. However, you should use this as a reflective tool only and not as a particular prediction.

History of Pythagorean Numerology: Pythagoras and the Modern System

Pythagoras was a Greek philosopher and mathematician who lived around 570-495 BCE. Pythagoras believed that numbers were the basis of order in the universe, from music and harmony to the movement of the stars and that everything in the universe could be understood through numbers. The Pythagoras number chart system is named in his honour because it follows his belief that numbers carry meaning. The modern letter chart, which assigns A to Z values from 1 to 9, took shape much later, mainly in the early 20th century, when Western numerologists and modern numerology writers popularised it.

Pythagorean Numerology Chart (A-Z Letter-Number Table)

In the Pythagoras numerology chart, each letter of the English alphabet is assigned a number from 1 to 9 in A-to-Z order. The sequence starts again after every ninth letter. For example, A, J and S have the value 1, while B, K and T have the value 2. Unlike the Chaldean chart, this system uses the number 9, and every number from 1 to 9 has letters. You can use the table below to turn any name into numbers.

Numbers	Letters
1	A, J, S
2	B, K, T
3	C, L, U
4	D, M, V
5	E, N, W
6	F, O, X
7	G, P, Y
8	H, Q, Z
9	I, R

Pythagorean Numerology Method: How to Calculate Your Numbers

To calculate your Pythagorean numerology numbers, first use the alphabet chart to replace letters with their numerical values, then add the values, and reduce the total to a single digit until you reach the numbers 11, 22 or 33, which are kept as they are because they are the master numbers.

Name Numerology (Pythagorean): Expression, Soul Urge and Personality

Pythagorean name numerology uses the letters of a person's name to calculate three important numbers, which include the Expression Number, Personality Number, and Soul Urge Number.

Expression Number: Your Expression Number is calculated from all the letters of your full birth name.
Soul Urge Number: Your Soul Urge Number is calculated from the vowels (A, E, I, O, U).
Personality Number: Your Personality Number is calculated from the consonants.

For example: Take the name Neha Kapoor

Using the Pythagorean alphabet chart:

Expression Number

Neha = N(5) + E(5) + H(8) + A(1) = 19
Kapoor = K(2) + A(1) + P(7) + O(6) + O(6) + R(9) = 31
Total = 19 + 31 = 50
Reduced number = 5 + 0 = 5

The Expression Number is 5.

Soul Urge Number

The vowels are E, A, A, O and O.

5 + 1 + 1 + 6 + 6 = 19, then 1 + 9 = 10, and 1 + 0 = 1.

The Soul Urge Number is 1.

Personality Number

The consonants are N, H, K, P and R.

5 + 8 + 2 + 7 + 9 = 31, then 3 + 1 = 4.

The Personality Number is 4.

Therefore, Neha Kapoor's numbers in this example are Expression 5, Soul Urge 1 and Personality 4.

Date of Birth Numbers

Pythagorean numerology also uses the date of birth to calculate the Life Path Number and the Birthday Number.

Life Path Number: For the Life Path Number, reduce the day, month and year separately, add the results, and reduce again.

For example, for 14 August 1990:

Day: 1 + 4 = 5
Month: 8
Year: 1 + 9 + 9 + 0 = 19, then 1 + 9 = 10, and 1 + 0 = 1
Total: 5 + 8 + 1 = 14, then 1 + 4 = 5

The Life Path Number is 5.

Birthday Number: The Birthday Number is simply the day of the month on which you were born. For someone born on the 14th, the Birthday Number is 1 + 4 = 5.

What Are the Master Numbers in Pythagorean Numerology?

Master numbers are the double-digit numbers 11, 22 and 33 and in Pythagorean numerology, these numbers are not reduced to a single digit when they appear as a final result or as a step in your calculation, such as the day, month or year in your life path. Each number has its own meaning.

Master Number 11: This number is associated with intuition, inspiration, and sensitivity. Its root digit is 2.

Pythagorean vs Chaldean Numerology

Numerology Chaldean and Pythagorean are the two main systems that are used for interpreting names and numbers. Both systems use numbers from 1 to 9, and both use a person’s name and date of birth for the calculation, but the main difference is how they assign numbers to letters.

Pythagorean numerology is simple and easy because it follows the A-Z order and gives importance to the life path number, while Chaldean numerology follows sound vibration and gives more importance to compound numbers.

Feature	Pythagorean numerology	Chaldean numerology
Letter assignment	A to Z sequence, repeating from 1 to 9	By sound vibration
Number 9	Used in the alphabet (I, R)	Not assigned to any letter in the standard chart
Compound numbers	Minor role	Central to the reading
Master numbers	Kept unreduced (11, 22, 33)	Treated as compound numbers (11/2, 22/4, 33/6)
Name emphasis	The birth name	The name you are known by
Typical audience	People interested in Western numerology and its core numbers	People interested in traditional Chaldean name numerology
