Tarot birth card calculator

What are tarot birth cards?

Tarot birth cards are the Major Arcana cards your date of birth adds up to. The method comes from Mary K. Greer, who built on Angeles Arrien’s work in Tarot for Your Self (1984) and expanded it in Who Are You in the Tarot? (2011). Think of them as a sun sign for tarot: a fixed reference point, not a prediction.

Most people get two cards:

• Personality card (10 to 22): how your life lesson looks day to day. Other people usually recognize it in you.
• Soul card (1 to 9): the root underneath, the purpose you keep coming back to. It is quieter and more private.

About six in ten people get a single card, because their total is already 9 or less. A few get three. The personality card vs soul card guide explains how to read the two together.

How to calculate your tarot birth cards

1. Add your birth month + day + four-digit year as whole numbers.
2. Add the digits of that total. If the answer is above 22, add its digits again.
3. The number you land on (1 to 22) is your personality card. 22 is The Fool.
4. Add the digits of the personality number until you reach a single digit. That is your soul card.

Example 1: two cards (April 13, 1975)

4 + 13 + 1975 = 1992 → 1 + 9 + 9 + 2 = 21 → 2 + 1 = 3

Personality card 21, The World. Soul card 3, The Empress.

Example 2: three cards (March 2, 1985)

3 + 2 + 1985 = 1990 → 1 + 9 + 9 + 0 = 19 → 1 + 9 = 10 → 1 + 0 = 1

19 is the only total that steps down twice, so this person has three cards: The Sun, Wheel of Fortune and The Magician. The Wheel sits in the middle as a bridge.

Example 3: one card (July 22, 1986)

7 + 22 + 1986 = 2015 → 2 + 0 + 1 + 5 = 8

The total is already a single digit, so Strength is both the personality and the soul card. A single card is not weaker. It means your outer style and inner purpose pull the same way.

Why another calculator may give a different card

Some sites add month + day + the first two digits of the year + the last two (April 13, 1975: 4 + 13 + 19 + 75 = 111 → 3). Others add all eight digits one at a time. Both shortcuts always give the same soul card as Greer’s method, but they can give a different personality card, as here: 3 instead of 21. Your result shows every method side by side. Why calculators disagree goes through each one.

All 22 possible birth card results

Every birth date gives one of these 22 results: a single card from 1 to 9, a pair, or the Sun, Wheel and Magician trio. The share column shows how common each one is for people born from 1950 to 2010; the last number is always the soul card.

Cards 10 to 22 only ever appear as personality cards, because they always reduce to a smaller soul number. Cards 1 to 9 can be either. Read your pair in depth on the birth card pairs page.

Your constellation and hidden factor card

Your soul card belongs to a constellation: the cards that reduce to the same single digit. Any card in it that is not one of your birth cards is your hidden factor or teacher card, a quality you tend to meet in other people or hard situations before you see it in yourself.

Constellations 1 to 4 have three cards, so they usually leave a hidden factor. Constellations 5 to 9 have two; if both are your birth cards, you have none. The constellations and hidden factor guide covers each one.

Birth cards vs other tarot cards from your birthday

Your birthday can point to several different Major Arcana cards. They answer different questions:

A year card that matches one of your birth cards often marks a year that feels like a turning point.

How to use your birth cards

• Look at the images. Open both card pages and note the first detail you notice. It often points to what matters for you right now.
• Ask three questions. Where do I see this card in my life? Where do I resist it? What would the healthiest version look like for me?
• Compare the pair. Note how the two cards differ. The friction between them is usually your life lesson.
• Watch for them in readings. When a birth card turns up in a spread, many readers take it as a sign the question touches something central to you.

Strength 8 or 11?

This calculator uses Rider-Waite-Smith numbering, as Greer does: Strength is 8 and Justice is 11. Marseille-style decks swap them. If your deck follows the Marseille order, read your number against your own deck. See Strength 8 or Justice 11 for the history.
