Free numerology lookup by name and birth date
Enter your Gregorian birth date in the box below and your Life Path number appears at once, with the Birthday and Attitude numbers and four Pinnacles; add your full name for Expression, Soul Urge and Personality — free, calculated right on the page. The tool reduces the birth month, day and year separately to one digit — keeping 11, 22 and 33 — then adds the three and reduces again: 15/05/1990 gives 5 + 6 + 1 = 12, which reduces to 1 + 2 = 3; it works deterministically, so the same birth date always gives the same number.

Which numbers does the tool calculate?
From a birth date alone, the tool returns your Life Path, Birthday number, Attitude number (day plus month), four Pinnacles with the age range of each stage, and the Challenge numbers. When you add your full name, its letters are stripped of accents and converted with the Pythagorean table to add Expression (all letters), Soul Urge (vowels), Personality (consonants) and the Maturity number (Life Path plus Expression). Every calculation is deterministic and runs on the server without AI: the same name and birth date always give the same numbers.
Example: the Life Path for 15 May 1990
Reduce each part first: month 5 stays 5; day 15 becomes 1 + 5 = 6; year 1990 becomes 1 + 9 + 9 + 0 = 19, then 1 + 9 = 10, then 1. Add the three parts: 5 + 6 + 1 = 12, and reduce once more: 1 + 2 = 3 — the Life Path is 3. The same birth date gives Birthday 6, Attitude 11 (5 + 6 = 11, kept because it is a master number) and four Pinnacles 11, 7, 9, 6 for the age stages 0–33, 34–42, 43–51, 52+.
Two conventions decide the final number: Inti Soul keeps 11, 22 and 33 instead of reducing them further; and when the total just before the last reduction is 13, 14, 16 or 19, the reading adds a karmic debt note — the number shown is still the reduced one. Sites using other conventions can give a different number.

Read the result as a question, not a label
A number does not say who you are or what will happen. Read it as a rhythm to watch for a few days: where it fits the way you live, and where it does not. To go deeper layer by layer, read what numerology is, the meaning of Life Path 1–9, 11, 22, 33, the four-pinnacle pyramid, the birth-date chart and its eight arrows and this year's personal year.
Frequently asked questions
Where can I read my numerology for free?
Right on this page. Enter a Gregorian birth date and your Life Path number appears at once — 15/05/1990 gives 3 — with the Birthday and Attitude numbers and four Pinnacles; add your full name for Expression, Soul Urge and Personality. Free, calculated right on the page, for people aged 18 and over. A free Inti Soul account gives you one overview numerology reading about yourself, written from your name and birth date — once, for life; topic-by-topic readings are part of Premium.
Which convention does the Life Path calculator use?
Reduce the Gregorian birth month, day and year separately (add their digits, keeping 11, 22 and 33), add the three results, then reduce to one digit — unless the total is 11, 22 or 33. For 29/11/1987: month 11 is kept, day 29 becomes 11, year 1987 becomes 25, then 7; 11 + 11 + 7 = 29, which reduces to 11 — Life Path 11.
Solar or lunar birth date?
The solar (Gregorian) birth date: the tool takes a Gregorian date and calculates on that date. If you only know your lunar birth date, convert it to the Gregorian calendar first.
Do I need an account?
You can preview it right on the page: a birth date alone gives your Life Path, Birthday and Attitude numbers, four Pinnacles and the Challenge numbers; add your full name for Expression, Soul Urge and Personality. A free account saves the reading and opens one overview interpretation.
Is AI involved in the result?
Not for the numbers on this page: they are computed deterministically from your name and birth date, and the same input always gives the same result. The reading in your account is an interpretation written by AI from exactly those numbers.
Is my birth date stored?
The reading is not written to the database. If you choose to create an account, what you entered is kept on your device only to continue where you left off.
