CALCULATION METHODS IN NUMEROLOGY

This chart was done with the free ChartMaker program.

Some differences exist among numerologists and their systems of calculations. We have done our best to maintain absolute integrity to the Pythagorean system based on extensive research covering more than three decades. If you have encountered some of those differences in your own research, consider this: All calculations in numerology are based on an underlying logic that is easy to recognize yet largely unknown even among many professional numerologists. 

Although the calculation methods are very simple -- a matter of adding or subtracting single- and double-digit numbers -- numerology is based on a rather complex cosmic network of inter-connecting patterns and cycles. These patterns and cycles are recognizable. It is in recognizing these patterns, that we are able to predict events and influences when certain criteria are met. 

What follows are short descriptions of how each number in the chart was calculated. Click any of the aspects listed below, or scroll further down the page and read about the aspects one at a time. 

NOTE:
When we talk about "reducing a number to a single-digit," we mean adding each of the digits until a single-digit is left. For example, we reduce the number 367 by adding 3 + 6 + 7 = 16. Next, we add 1 + 6 = 7. We have now reduced the number 367 to the single-digit number 7.

NOTE: In many areas of your chart, Master numbers are not reduced during the calculations. For example, to reduce the year 1966 to a single digit, we add 1+9+6+6=22. Twenty-two is a Master number, therefore, we do not reduce 22 any further. 
Many numerologists will write 22/4, because the 22 is also a 4. This is purely a matter of personal preference.

THE LIFE PATH

Excerpt from the book Numerology; Key To Your Inner Self.

YOUR DATE OF BIRTH -- A DOORWAY IN TIME

We don't do what we want and yet we are responsible for what we are -- that is the fact.
Jean Paul Sartre

If ever there was a moment of total transformation, it was the moment of your birth. In that instant, you stepped through a door in time into a new reality -- the reality of human life. You left behind the memory of what was before, and entered the physical realm in the purest condition: untouched by this world; not yet influenced; not yet inhibited; and free of concepts  expectations, judgments, and self-consciousness. (Small wonder that everybody around you instantly fell in love with you!)

Yet, even at that moment, you were a person with your own unique character, as unique as your DNA. Everything that is you existed in potential, much like a play that is about to begin.

Your life is indeed like a play. Birth is the raising of the curtain; death the curtain's descent. The play has evolved through various stages of preparation, but does not really begin until you are born. 
When all the players go on stage, they have been prepared for their parts. Their characters are outlined, and the stage is set. At the moment the curtain is raised, the play itself exists as a potential within the characters, the director, the musicians, and the audience. 

In the same way, the moment of your birth provides that broad outline for your life. Your entire life exists as a potential that has been prepared for. You have ultimate freedom to do with your life as you like: To fulfill its potential completely, or to make some smaller version of yourself. It all depends upon your effort and commitment. You make the decisions to fulfill, to whatever extent, the potential life that exists within you. That is your choice. In this sense, the possible you is implicit during the moment of your birth. 

The Life Path number.

The most important number in your numerology chart is based on the date of your birth, the moment when the curtain goes up in your life. This number is called the Life Path number. It can be compared to the plot of a potential play. The Life Path number gives us a broad outline of the opportunities, challenges, and lessons we will encounter in this lifetime.

End of excerpt.

The Life Path, as is the case with all numbers derived from your date of birth, has to do with the momentum, the direction, of your life. The Life Path is a cycle.

MATHEMATICAL PROCEDURES in NUMEROLOGY

How to Find Your Life Path number.

First, we reduce each unit (month/day/year) of the birth date to a single-digit or a Master number. 
Next we add each of the resulting digits (or Master numbers) together and reduce the total again to a single-digit.
Example:
October 12, 1936.
October is the 10th month. Reduce 10 to a single-digit. 1 + 0 = 1
The day of birth is 12. We reduce 12 to 3 (1 + 2 = 3)
The year of birth is 1936. We reduce 1936 to 1 + 9 + 3 + 6 = 19. 1 + 9 = 10. 1 + 0 = 1. The year 1936 reduces to 1.

We now add the resulting single digits.

month = 1, day = 3, year = 1. Total is 5

The Life Path number is 5. 

Another example: November 22, 1911
November is the 11th month. The 11 is a Master number and is not reduced. 
The 22nd day is also a Master number: 22. 
The year 1911 reduces to 12, which reduces to 3.

We reduce 36 to 9. The Life Path is 9.

THE BIRTH DAY NUMBER.

About the Birth Day number:
The day you were born bears great significance in understanding who you are and where your talents lie. The day of birth indicates some special talent you possess. It is a gift to you that will help you along your Life's Path. Your day of birth is one of your four core numbers -- the Life Path, Expression, Heart's Desire, and Personality being the other four. It is the least significant of the five core numbers, but perhaps the most finite, in that it reveals a specific ability you possess in a marked degree.

Your Birth Day number is the number of the day you were born, and is examined as both a single- and a double-digit number. The reason for this twofold way of looking at the number is that a double-digit Birth Day number suggests that you possess additional characteristics not directly revealed by the single-digit number. For example, a person born on day 15 can be said to have a 6 Birth Day number (1 + 5), but the double digits, the 1 and the 5, suggest other abilities and character traits not revealed by the 6 alone. The 15 brings very different underlying talents to the 6 than does the 24, which is derived from the 2 and the 4, also a 6, but is quite different in nature. This is particularly important when understanding the Birth Day number, and for that reason all thirty-one Birth Days are described separately.
