how to find your Your Challenge number

Challenge number

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. Most of us overcome our Challenges at least to some extend, if not entirely.
The duration of the First Challenge usually lasts from birth until approximately the age of 30 to 35. The Second Challenge most strongly influences you during the middle part of your life until about age 55 to 60. The Third Challenge is also called your Main Challenge and is felt throughout life. The Fourth and Final Challenge starts around age 60 to 65.
Before we guide you to your First Challenge number, you may want to take a look here, to learn more about the calculation methods for Challenges. 

Challenges are one of the few areas in numerology where we deduct numbers!
Your First Challenge is calculated by subtracting your month from your day of birth, or vice versa. It is the difference between the month and day of birth.
Because we subtract, a result of 0 (zero) is possible.
It is also quite common to have a Challenge repeat more than once

example: birth month = June =06 
               birth day      =03 =    03
1st challenge number  = 6 - 3 = 03          

Next, deduct the value of the month from the value of the day, or vice versa and refer to the table below to find your First Challenge number. (Make a note of your First Challenge number - you will need it later.)
