A life path number is a term used in numerology, a belief system that attributes meaning to numbers and their influence on human life. It is calculated based on an individual's birth date and is said to reveal insights into one's personality, strengths, weaknesses, and life purpose. The life path number is derived by adding the digits of the birth date together and reducing the sum to a single digit, except for master numbers 11, 22, and 33, which are not reduced further. For example, someone born on May 15, 1990, would calculate their life path number as follows: 5 (May) + 1 + 5 (day) + 1 + 9 + 9 + 0 = 30, which reduces to 3 (3 + 0 = 3). In Hebrew, the term can be translated as מספר מסלול החיים (mispar maslul ha-chayim). Other relevant translations include Zahl des Lebenswegs in German and número do caminho da vida in Portuguese. Numerology enthusiasts believe that understanding one's life path number can provide guidance and self-awareness, though it is important to note that numerology is not scientifically validated and is considered a pseudoscience.
