## What Arcana Calculator is

Arcana Calculator is a free tarot-numerology and symbolic reflection site. It calculates repeatable Major Arcana correspondences from birth dates, explains the arithmetic used, and provides original interpretations covering constructive resources, possible shadows, love, personality, and practical reflection prompts.

The site does not claim that tarot numerology is scientific, diagnostic, or predictive. A result is an archetypal prompt whose usefulness should be compared with lived evidence. It cannot establish health, morality, compatibility, another person's private motives, relationship safety, or future events. Medical, psychological, legal, financial, and safety decisions require appropriate evidence and qualified help.

## Calculator inputs and privacy

The single-person calculators ask for one complete birth date. Couple and Compatibility ask for two complete birth dates. Birth dates affect the arithmetic; the calculator does not require an account, email address, or submitted form.

Calculation happens locally in the browser. The site has no account system or calculator-entry database and does not submit entered dates when the user reveals a result. A copied share link contains one or two complete birth dates so another browser can reproduce the result. Users should not share a link containing details they consider sensitive.

Google Analytics measures aggregate page usage with advertising signals disabled. Analytics page-location values are limited to the origin and pathname, excluding birth-date query parameters. A hosting provider may still process ordinary request logs for security and service delivery.

## Calculation method 1: Single Arcana

Single Arcana is used by the homepage, Love, Couple, and Compatibility calculators and is available as an option on Personality.

1. Validate a real, non-future birth date.
2. Add every digit in the four-digit year, month, and day.
3. If the total is above 22, add the digits in that total.
4. Repeat only while the total remains above 22.
5. Map the final value from 1 through 22 to the Major Arcana sequence below.

Example: 15 May 1990 is written 15/05/1990. The digits total 1 + 5 + 0 + 5 + 1 + 9 + 9 + 0 = 30. Because 30 is above 22, reduce 3 + 0 = 3. The result is The Empress.

Values 10 through 22 remain valid Major Arcana numbers and are not automatically reduced to a single digit. This site maps 1–21 to The Magician through The World and maps 22 to The Fool. Many tarot decks print The Fool as 0; using 22 here is an explicit calculation convention.

## Calculation method 2: Personality / Soul

Personality / Soul is optional and appears only on the dedicated Personality calculator.

1. Split the four-digit year into its century and year-within-century.
2. Add numerical month + numerical day + century + year-within-century.
3. For totals of 100 or more, add the leading two digits as a number to the final digit. For example, 129 becomes 12 + 9 = 21.
4. If a remaining total is above 22, reduce it by digit sum until it reaches a Major Arcana value.
5. Retain that Major Arcana as the Personality card, then reduce a two-digit card again to obtain the Soul card. The 19 path retains The Sun, then Wheel of Fortune, then The Magician.

Example: 15 May 1990 gives 5 + 15 + 19 + 90 = 129, then 12 + 9 = 21. The Personality card is The World. Reducing 2 + 1 = 3 gives The Empress as the Soul card.

These are two transparent conventions among several tarot birth-card traditions. Other sources may group or reduce dates differently or treat The Fool differently. A different published formula can legitimately produce a different result.

## Couple and Compatibility calculations

Both two-person tools calculate one Single Arcana card for each birth date. Couple presents a qualitative romantic reading and deliberately avoids making a numerical score the headline. Compatibility adds a playful symbolic index based on circular card-number distance and whether both cards share an element. The index is clamped between 48 and 96 and is not a scientific measure of relationship quality.

## Editorial and attribution

Arcana Calculator separates each archetype's constructive resource, possible shadow, and practical question. Copy avoids deterministic promises, asks readers to compare symbolism with concrete examples, and treats consent and real-world safety as more important than a card correspondence.

Card illustrations are public-domain Rider–Waite–Smith imagery illustrated by Pamela Colman Smith and first published in 1909. The site maintains its own original explanatory and interpretive copy.
