Numerology is an ancient metaphysical system that assigns numerical values to letters and numbers, and it believes that these numbers carry specific vibrations and energies. By understanding the meanings and symbolism behind numbers, numerologists believe they can gain insight into a person's personality traits, life path, and even future events. Here are the main principles of numerology:

Life Path Number: One of the most important numbers in numerology is the Life Path number. It is derived from a person's date of birth and represents the core essence of their life's journey. Calculating the Life Path number involves reducing the birthdate to a single-digit or master number. For example, someone born on November 10, 1985, would have a Life Path number of 1 (1+1+1+0+1+9+8+5=26, and 2+6=8).

Expression Number: The Expression number is also known as the Destiny or Name number. It is derived from the full birth name and reveals a person's natural talents, abilities, and potential. Each letter in the name is assigned a numerical value, and the numbers are then added together and reduced to a single digit or master number.

Soul Urge Number: The Soul Urge number represents a person's innermost desires, motivations, and emotional needs. It is calculated using the vowels in a person's full birth name. Each vowel is assigned a numerical value, and the numbers are added together and reduced to a single digit or master number.

Personal Year Number: The Personal Year number provides insight into the theme and energy that will be predominant during a particular year. It is calculated using the month and day of birth, combined with the current calendar year. The resulting number can help individuals understand the opportunities, challenges, and lessons they may encounter during a specific year.
