reference : 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 .
Next we add each of the resulting digits (or Master numbers) together and reduce the total again to a single-digit.
Food for thought:
This age-old method is founded on the concept that your Life Path is based on your three Period Cycles. Therefore, in order to calculate your Life Path number, you actually calculate your Period Cycles first. Your three Period Cycles are based on your month, day, and year of birth, and represent the early, middle, and later part of your life respectively. Your complete life's cycle — your Life Path — has all the attributes reflected in the Life Path's number. However, the Life Path is also influenced by the properties and traits revealed in each of these Period Cycles.
While there are three ways to calculate the Life Path, most numerologists, consider those methods flawed, because they are not based on the Period Cycles, thereby ignoring the logic on which this science is based.
A: The method used in our examples and considered correct by most numerologists. Example: May 15, 1949 would be 5 + 6 (the 15th day reduced to 6) + 5 (the year 1949 reduced to 23 and then 5) = 16/7.
B: Adds the month + day + year = sum, and then reduced. Example: May 15, 1949 would be 5 + 15 + 1949 = 1969, which reduces to 25/7. This method is used by very few numerologists, if any.
C: Adds each single digit as it appears in the date of birth. For example, May 15, 1949 would be
5 + 1 + 5 + 1 + 9 + 4 + 9 = 34/7.
Notice that we used the same date in all three examples but the results were different in each case: 16/7, 25/7, and 34/7. Using the prevailing method reveals a 16 Karmic Debt
