Your Personality Number is the sum of the consonants in your full name reduced to a single digit, with 11, 22 and 33 kept as master numbers. It is read as the outer self: the first impression and image people pick up before they know you well. Enter your name to calculate it, see the consonant total, and read the ruling planet of the root.
Because it is drawn only from the consonants of your name, the Personality Number describes your outer self - the way you present before others reach your inner world. It works like a first layer, the part of you people meet and read at a glance.
It is the narrower of the three name numbers. The vowels are set aside entirely, so nothing of what you privately want enters the figure; what remains is the consonant frame of the name, which numerology treats as the surface people meet first. Read it beside the Soul Urge rather than instead of it.
In name numerology your letters divide three ways. The vowels give your Soul Urge, the consonants give your Personality Number, and all the letters together give your Expression (Destiny) number - so Personality is one piece of your full name reading.
The three are computed from the same letters, so they are arithmetically related rather than independent: in the Pythagorean system the vowel sum and the consonant sum add up to the full-name total before any of the three is reduced. That is why a Personality Number on its own is a partial reading, and why the Expression number is the one that accounts for every letter.
Every letter that is not A, E, I, O or U is treated as a consonant here, and that includes Y. Each one takes its value from the Pythagorean cyclic table: A=1 through I=9, then J=1 through R=9, then S=1 through Z=8. The values are added across the whole name and the total is then reduced.
The reduction keeps the master numbers, so a consonant total of 11, 22 or 33 is left standing and everything else falls to a single digit from 1 to 9. Only the letters A to Z are counted at all, which means spaces, hyphens, apostrophes and the full stops after initials make no difference to the sum. Enter the name in the exact form you want read.
