Tarot and Numerology: How Numbers Link the Two
The Short Answer: Two Languages That Share Numbers
Tarot and numerology are two symbolic languages that speak through numbers: both read a number as a theme, not as a fact. Both share the same raw material, the numbers 1 to 10 and the Major Arcana sequence 0 to 21, yet each uses it in its own way. In tarot, a number sets the stage and the suit sets the arena. In numerology, a birth date or a name reduces to a number that names a broad pattern. Neither system is scientifically validated, and neither one can guarantee an outcome, a date, or a yes or no answer.
The Number Ladder in Tarot: Ace to Ten
A standard tarot deck holds 78 cards: 22 Major Arcana and 56 Minor Arcana. The Rider-Waite-Smith deck, published in 1909 and illustrated by Pamela Colman Smith, is the deck most number meanings are built on. There, Strength is card 8 and Justice is card 11.
The Minor Arcana runs Ace to Ten in each of four suits, and the number carries the same broad theme in every suit. The suit tells you where it plays out: Wands action, Cups emotion, Swords thought, Pentacles material life. The ladder: Aces new beginnings; Twos balance and choice; Threes growth and expression; Fours structure and stability; Fives change and disruption; Sixes harmony and adjustment; Sevens reflection and challenge; Eights power and movement; Nines near completion; Tens completion, the end of a cycle.
The digits 1 to 9 also map to the first nine Major Arcana cards: 1 The Magician, 2 The High Priestess, 3 The Empress, 4 The Emperor, 5 Hierophant, 6 Lovers, 7 Chariot, 8 Strength, 9 The Hermit.
Two Ways to Read a Name: Pythagorean and Chaldean
Numerology also reads numbers from names, and the two dominant Western systems disagree about how letters become numbers, which shows the charts are human conventions, not discoveries of nature.
The Pythagorean system assigns letters 1 to 9 in strict alphabetical order: 1 is A, J, S; 2 is B, K, T; 3 is C, L, U; 4 is D, M, V; 5 is E, N, W; 6 is F, O, X; 7 is G, P, Y; 8 is H, Q, Z; 9 is I, R. Read the full birth name as written on the birth certificate, and reduce the total to one digit, except for master numbers 11, 22, and 33, which stay whole as intensified forms of 2, 4, and 6.
The Chaldean system assigns letters by sound vibration rather than by alphabet order, using only the numbers 1 to 8. No letter carries the number 9. The chart: 1 is A, I, J, Q, Y; 2 is B, K, R; 3 is C, G, L, S; 4 is D, M, T; 5 is E, H, N, X; 6 is U, V, W; 7 is O, Z; 8 is F, P. Read the name as currently used, and read two digit totals before reducing them.
YES shows the difference: Pythagorean 7 plus 5 plus 1, total 13, then 4, and Chaldean 1 plus 5 plus 1, total 7. Pick one system and stay with it for a whole reading.
Pythagoras of Samos, who lived around 570 to 495 BCE, taught that number was the fundamental substance of reality, but he did not invent the modern letter chart. That chart came later, shaped in large part by L. Dow Balliett in the early twentieth century. For more, see what is numerology.
Your Life Path Number, Step by Step
The Life Path number is the best known number in numerology. It comes from the full birth date and is read as the broad path a life follows: a theme, not a verdict.
The standard method reduces month, day, and year separately, then adds the three results and reduces again if needed. If any component reduces to a master number, 11, 22, or 33, keep it whole: a birth day of 29 reduces to 11 and stays 11.
September 14, 1987: 9, 14 to 5, 1987 to 25 then 7; 9 plus 5 plus 7 is 21, then 3. Life Path 3. December 14, 1992: 12 to 3, 14 to 5, 1992 to 21 then 3; 3 plus 5 plus 3 is 11, a master number. Life Path 11. June 15, 1990: 6, 15 to 6, 1990 to 19, then 10, then 1; 6 plus 6 plus 1 is 13, then 4. Life Path 4.
Some calculators add all the digits of the full birth date in one string and then reduce, and that variant can give a different result on master numbers.
No full list of meanings for Life Path numbers 1 to 9 is given here, because that list was not verified entry by entry.
Birth Cards: Your Date as Major Arcana
Birth cards translate a birth date into Major Arcana cards. The method was developed by Angeles Arrien and first published by Mary K. Greer in Tarot for Your Self in 1984. A birth card never changes: it is a lifelong archetype, not a prediction.
The Greer method has four steps. First, add the month, the day, and the full year as whole numbers. Second, add the digits of that total until the result is 22 or less: that is the Personality Card. Third, reduce it to a single digit: that is the Soul Card. Fourth, the two special cases: the Fool is numbered 0 in the deck but counts as 22, and a total of exactly 19 gives three cards instead of two.
July 23, 1988: 7 plus 23 plus 1988 is 2018; 2 plus 0 plus 1 plus 8 is 11. Personality Card 11, Justice; 1 plus 1 is 2. Soul Card 2, The High Priestess.
Greer groups the cards into nine constellations sharing a Soul Card: 3 The Empress with 12 Hanged Man; 4 The Emperor with 13 Death; 5 Hierophant with 14 Temperance; 6 Lovers with 15 Devil; 7 Chariot with 16 Tower; 8 Strength with 17 Star; 9 The Hermit with 18 Moon; 10 Wheel of Fortune with 19 The Sun; 11 Justice with 2 The High Priestess. Nineteen is the only three card case: Sun at 19, Wheel of Fortune at 10, and The Magician at 1.
Numbering here follows the Rider-Waite-Smith deck, where Strength is 8 and Justice is 11. On a Marseille deck the two swap, so check the deck before you compare results.
Where the Methods Disagree
Readers disagree about method in three places.
First, the Life Path dispute: the component method reduces month, day, and year separately, while the all digits method adds every digit at once. The two usually agree on the final digit but can differ on master numbers.
Second, the birth card dispute: the Greer method adds month, day, and year as whole numbers, while the Tarot School method adds every digit individually and pairs a single digit result with a fixed higher card, so 4 is always shown with 13, Death. The two methods always agree on the Soul Card and often disagree on the Personality Card.
Third, the label dispute: some sources swap the Personality and Soul labels. This guide follows Greer and Tarot Nova: the two digit number is the Personality Card, the single digit the Soul Card.
One hard limit applies to every number here: numbers do not provide guaranteed timing, yes or no answers, or instructions about which direction you must take in life.
How to Use Both Systems in a Reading
Start simple: read a card by number plus suit. The number gives the stage and the suit gives the arena. For the full set of card meanings, see all 78 tarot card meanings.
Then add the Life Path number as a lens. A Life Path 1 querent who pulls several Aces and The Magician sees the same beginning theme in two languages at once. The repetition proves nothing, but it gives the reading a thread to follow.
Birth cards work best as background. The Personality Card describes how you go about things, and the Soul Card describes what that way of working is trying to reach. They never change, so they are a poor tool for timing and a good tool for self knowledge. For how tarot meets a different symbolic system, see tarot and astrology.
What to Do Now
Work out your Life Path number, then find your birth cards, and compare both with the number ladder. If the same theme appears in all three places, sit with it for a week. If the methods disagree, note it and move on: a disputed number is information about the systems, not a verdict about you.

Frequently Asked Questions
What is the link between tarot and numerology?
Both systems read numbers as themes. Tarot gives every card a number, from the Fool at 0 through the Major Arcana to the Ace to Ten of each Minor Arcana suit, and numerology reduces a birth date or a name to a number. The same number carries the same broad theme in both languages, so 1 means beginning in an Ace, in the Magician, and in a Life Path 1. Neither system is scientifically validated, and neither one can guarantee an outcome.
How do I calculate my Life Path number?
Reduce the month, the day, and the year separately to single digits, then add the three results and reduce again if needed. Keep master numbers 11, 22, and 33 whole instead of reducing them. For example, September 14, 1987 gives 9 plus 5 plus 7, which totals 21 and reduces to 3, so the Life Path number is 3. Some calculators add all the digits at once instead, and that variant can give a different master number result.
What are tarot birth cards?
Birth cards are the Major Arcana cards encoded in a birth date, using the method Mary K. Greer published in Tarot for Your Self in 1984. Add the month, the day, and the full year as whole numbers, then add the digits of that total until the result is 22 or less. That number is the Personality Card, and reducing it to a single digit gives the Soul Card. For July 23, 1988, the Personality Card is 11, Justice, and the Soul Card is 2, the High Priestess. Birth cards never change, and they are read as lifelong archetypes, not as predictions.
Why do Pythagorean and Chaldean numerology give different answers for the same name?
The two systems use different letter charts. The Pythagorean chart assigns letters 1 to 9 in alphabetical order, while the Chaldean chart assigns letters 1 to 8 by sound vibration and gives no letter the number 9. The name YES totals 13 and reduces to 4 in the Pythagorean chart, but totals 7 in the Chaldean chart. Neither answer is wrong inside its own system, so pick one system and stay with it for a whole reading.
Can tarot and numerology predict the future?
No. Both are interpretive and symbolic systems, not scientifically validated methods of prediction. Numbers can frame a question, highlight a theme, and give a reading a thread to follow, but they cannot provide guaranteed timing, yes or no answers, or reliable dates. A reading that promises a date or a guaranteed outcome from a number is overpromising, whatever system it claims to use.
