Numerology Challenges is one of the few areas of numerology where subtraction is used.

The Challenges are derived from your date of birth, using the month, the day, and the year, in that order. Use the following formula. (I will use an example to make the steps easier to understand.)

NOTE: When calculating your Challenge Numbers, all Master Numbers are reduced to single digits.

Numerology chart showing Challenge numbers - Challenges are found by deducting numbers

The Challenges are located below the birth date in the numerology chart.

In our example of Tom Cruise, born 7/3/1962, we reduce each of these units (the month, the day, and the year) to single digits. The result is 7, 3, 9.

To find the First Numerology Challenge number we subtract the month of birth from the day of birth, or vice versa. In our example, we subtract 3 from 7 = 4.

The Second Numerology Challenge results from subtracting the day of birth from the year of birth, or vice versa. In our example, we deduct 3 from 9 = 6.

The Third and main Numerology Challenge is found by subtracting the First and Second Challenge, or vice versa. In our example, 6 – 4 = 2.

NOTE: The 0 Challenge is very common.

The Fourth Challenge is found by subtracting the month of birth from the year of birth, or vice versa. In our example, we deduct 7 from 9 = 2.

In short:

The 1st Challenge is the difference between the month and day of birth.

The 2nd Challenge is the difference between the day and year of birth.

The 3rd or Main Challenge equals the difference between the 1st and 2nd Challenge

The 4th Challenge is the difference between the month and year of birth.

Notice that the First Challenge appears below the month and day of birth, the Second Challenge below the day and year of birth, the Third or Main Challenge is centered directly below the day of birth, while the Fourth Challenge fills the lower triangle of this star-shaped arrangement.


Each of us is born with both strengths and weaknesses. Numerology looks at life as if it were an educational process that is meant to bring out and enhance our talents, and turn our weaknesses into strengths. This serves to complete our being.

The job of becoming whole is one in which we must face our weaknesses and consciously work to improve ourselves. There are four Challenges to be faced during our lives. For many of us, the same challenge is repeated, while others have four distinctly different lessons to learn.

The Challenges on your life’s path provide specific lessons that you must attend to, and, in order to inspire and help you, life will place you in situations that require the specific characteristics of your Challenge numbers.

The four Challenges you are required to overcome during the course of this lifetime will influence you during different periods of your life, except for the Third or Main Challenge, which lasts from birth until death.

The Challenges are fluid periods of your life, not confined to specific years so much as general periods. All of your Challenges are present at birth, like actors standing in the wings.


The duration of the First Challenge usually lasts from birth until approximately the age of 30 to 35.

The Second Challenge usually lasts until the age of about 35 to 55/60.

This Challenge carries much weight and will be felt throughout your life. For that reason, it is also called the Main Challenge.

As you master this challenge, your life will come more and more under your own control. You will incorporate the positive aspects of the challenge into your character. This is it’s purpose in the first place. Therefore, there is implicit in the challenge a chance for great reward.

In short, this may be the secret to your success.

The Fourth Challenge is most strongly felt during the latter part of our lives, beginning at the age of approximately 55/60.
