Your numbers, in plain language.
Numerology reads the same birth details your chart uses, your date and full name, as a small set of numbers. Here is what each one means, without the jargon.
Where the six numbers come from
Numerology reduces two pieces of information, your full birth name and your date of birth, to single digits. Crescent computes six of them rather than the one most sites stop at, because they are drawn from different source material and describe different things.
Life Path comes from your birth date, added together and reduced. It is the most quoted number and the closest thing numerology has to a Sun sign. Expression comes from every letter of your full birth name and describes natural aptitude. Soul Urge uses only the vowels in that name and is read as private motivation, the thing you want without announcing it. Personality uses only the consonants and describes the version of you other people meet first.
Birthday is simply the day of the month you were born, unreduced, and is read as one specific talent. Personal Year is the only number that moves: it combines your birth day and month with the current year and cycles from one to nine, so it describes the chapter you are in rather than who you are.
Master numbers
Most totals reduce to a single digit, but 11, 22 and 33 are conventionally left alone and treated as master numbers. Crescent preserves them rather than reducing 11 to 2, because collapsing them discards the distinction the system is making.
Why the full birth name matters
The name numbers are computed from the name on your birth certificate, not the name you use day to day. Nicknames, married names and anglicised spellings all produce different totals, which is the most common reason two numerology sites disagree about the same person. If your result looks wrong, the input is almost always the reason.
How this relates to your chart
Numerology and astrology are separate systems with separate histories, and neither derives from the other. They are offered side by side here because they take almost the same input. If you would rather see what the sky itself was doing at your birth, Crescent computes a full natal chart from a real ephemeris, and the glossary of core concepts explains how that differs from a horoscope.
