How numerology numbers are calculated
The Pythagorean system of numerology assigns a numeric value (1–9) to each letter of the alphabet in sequence. Your Life Path number comes from your birth date: the day, month, and year are each reduced to a single digit, then summed and reduced again. The Destiny number comes from your full birth name: each letter's numeric value is summed and reduced.
The reduction process repeatedly sums the digits of a number until a single digit (1–9) or master number (11, 22, 33) remains. Master numbers are considered more powerful and are not reduced further. For example, 1990 reduces as 1+9+9+0 = 19, then 1+9 = 10, then 1+0 = 1.

Tips for numerology
Use your full birth name
The Destiny number should be calculated from your full legal name at birth, not a nickname or married name. This is considered the most accurate in Pythagorean numerology.
Master numbers are special
If your calculation produces 11, 22, or 33, those are master numbers with their own distinct meanings. They are not reduced to 2, 4, or 6.
