How Tarot Numerology Works: The Complete Formula

There's nothing to take on faith here. Every card the Tarot Almanac shows you comes from arithmetic you can do yourself, with no step hidden and no number pulled out of the air. This post lays out the whole calculation, start to finish, so you can recreate any reading at your kitchen table.

If you've read What Is Tarot Numerology?, you already have the core move: instead of reducing a date down to a small number, the Almanac wraps a running total around the twenty-two Major Arcana, which sit in a circle from the Fool at 0 to the World at 21. The card you land on is your position on that wheel, and the wrapping is one operation, divide by 22 and keep the remainder. That single idea runs the whole system. Everything below is just deciding what to add up before you wrap, and what to do once you get to the day.

Two readings from one calculation

The Almanac gives you two parallel readings, built the same way. The collective reading is the same for everyone alive on a given day, made from the date alone. The personal reading is yours, made from your birthday folded into that same date. Both run through three layers, a year, a month, and a day, and the layers stack, each feeding the next.

The year and the month are Major Arcana

The first two layers place you on the wheel of twenty-two, exactly as the first post described.

Collective Year. Add the digits of the year, then wrap. For 2026: 2 + 0 + 2 + 6 = 10, which is already inside the range, so the collective year card for all of 2026 is card 10, the Wheel of Fortune. Everyone shares it for the whole year.

Collective Month. Take the year card and add the month's number. June is the sixth month, so 10 + 6 = 16, the Tower. That's the collective month card for June 2026.

Personal Year and Month work identically, with one addition: your birthday joins the year at the first step. Add your birth month, your birth day, and the digit-sum of the year, then wrap, and carry that forward into the month the same way. Your birth year never enters, because the reading is about where you stand in the cycle now, not how many turns you've taken around it.

So far, every card is a Major, and you can do all of it in your head.

The day is a Minor, and it works differently

Here the system changes shape, on purpose.

The Major Arcana are the shape of a day, the archetype it belongs to, where you are in the larger cycle. But a day has a texture as well as a shape, the specific grain of how that archetype actually shows up, and texture is the work of the Minor Arcana. So the day card isn't another Major. It's one of the fifty-six Minors, and it's drawn so that the texture always belongs to the day's shape rather than fighting it.

That principle is the whole of it, so it's worth saying plainly: the minor of the day should express the day's Major, never contradict it. A day whose shape is the World should not hand you a texture that argues with the World. Hold the minor to its Major in one half and set it free in the other, and the principle takes care of itself.

The suit comes from the day's Major. Every Major Arcana carries one of the four classical elements, the correspondences the Golden Dawn fixed in the 1880s, and each element owns a suit. Fire is Wands, Water is Cups, Air is Swords, Earth is Pentacles. So the day's Major decides the suit, and that single tie is what keeps the texture true to the shape. The World is an earth card, so a World day is always a Pentacles day, grounded and material, whatever else happens. It can't come out as a suit that would pull against the day.

The rank ranges freely. Within that suit, the specific card, Ace through King, comes from the date itself. You take the date as a number and run it through a fixed step: multiply by eleven, divide by fourteen, keep the remainder, and add one to land on a rank from one to fourteen. Three numbers do three jobs there, and each has a reason.

The fourteen is the simplest. A suit has fourteen cards, Ace through Ten and then the four court cards, Page, Knight, Queen, King. Dividing by fourteen and keeping the remainder is the same wrapping move the Majors use, just on a fourteen-seat wheel instead of a twenty-two-seat one. It guarantees you land somewhere inside a single suit and nowhere else, no matter how large the date number is.

The plus one is there because of where that wrapping starts. A remainder always begins at zero, so dividing by fourteen gives you a number from zero to thirteen. But the ranks don't have a zero card, they start at the Ace, which is one. Adding one shifts the whole range up by a step, from zero-through-thirteen to one-through-fourteen, so it lines up exactly with Ace through King with nothing left over and no empty seat. It's the same reasoning that puts the Fool at zero in the Majors, run in the other direction: the Majors have a zero card and start there, the suits don't and start at one.

The eleven is the one that isn't pure plumbing. Eleven is the master number, the first of the values numerology refuses to reduce, the one held to be a heightened vibration rather than something to collapse. The whole Almanac is built on reduction and wrapping, and the rank of the day is paced by the one number that resists reduction. It also does honest mathematical work: because eleven shares no factor with fourteen, stepping by it reaches every rank in turn and never falls into a rut, so over time all fourteen ranks come up, and all fifty-six Minors become reachable. A number with no common factor would do the job mechanically; eleven does it and means something.

That last part matters more than it might seem, and it's why the day resolves this way instead of more simply. If the rank were tied to the Major the way the suit is, only a handful of the Minors could ever appear, and the deck would quietly lose most of itself, the same flaw that troubled traditional numerology in the first post. But letting the suit hold the day while the rank runs free gives both things at once: a texture that always fits the day, and a full deck where any of the fifty-six can come. The two requirements look opposed until you see that the suit and the rank can answer them separately, and then they aren't opposed at all.

A day worked through

Take June 8, 2026. The collective month card is the Tower, so the day card counts forward from there: 16 + 8 = 24, which wraps to 2, the High Priestess. That's the day's shape.

Now the texture. The High Priestess is a water card, so the suit is Cups. For the rank, take the date as a number, 20260608, multiply by eleven, divide by fourteen, and the remainder is 2, so the rank is 2 + 1 = 3. The collective texture of June 8 is the Three of Cups, a watery card of shared joy, sitting inside a High Priestess day.

The next day shows the freedom in the rank. June 9's shape is the Empress, an earth card, so Pentacles. Run 20260609 through the same step and the rank lands on King. The Empress day reads as the King of Pentacles, a different suit and a far higher rank than the day before, with no climb between them. The texture moved because the date moved, not because it's marching.

The whole thing on one card

Here is every formula in one place. Wrap means divide by 22 and keep the remainder.

• Collective Year = (digit-sum of the year), wrapped
• Collective Month = (Collective Year + month number), wrapped
• Collective Day Major = (Collective Month + day of month), wrapped
• Personal Year = (birth month + birth day + digit-sum of the year), wrapped
• Personal Month = (Personal Year + month number), wrapped
• Personal Day Major = (Personal Month + day of month), wrapped

Then the day's Minor, from its Major:

• Suit = the element of the day's Major (Fire → Wands, Water → Cups, Air → Swords, Earth → Pentacles)
• Rank = (the date as a number × 11), divided by 14, remainder, plus 1

For the personal day, the date number has your birthday folded in, so your texture is yours and no two people born on different days share it.

That's the complete system. A handful of small additions, one wrap, and one step for the rank, with no randomness anywhere in it. The code that runs the live Almanac does exactly this and nothing more, which is why two people working the arithmetic by hand will land on the same cards the app does.

Why publish it at all

Most divination keeps its method behind a curtain, because the mystery is the product. The Almanac runs the other way. The math being open is what makes it trustworthy: you don't have to believe me about where you are on the wheel or what the texture of your day is, you can check. Tarot has always grown this way, one practitioner at a time noticing a structure that was already latent in the cards and naming it, the Golden Dawn finding the order and the elements, Waite and Smith fixing the images in 1909. The timing was the layer waiting to be noticed, and a layer you can verify is a layer you can actually stand on.
