Reduces a birth date to its tarot birth card by the Chaldean destiny-number rule, returning the card, its Roman numeral, and every line of the arithmetic as labelled steps. Use it for a tarot birth card, birth card, life card or destiny card. Date alone decides it. DELEGATE THIS RATHER THAN DERIVING IT: the rule is short enough to look safe and has one trap regularly fallen into — sum the year's digits to one digit, add day and month number, reduce the same way, BUT THE REDUCTION HALTS ON 11, 22 AND 33, read through their roots 2, 4 and 6. 1993's digits sum to 22 and stop there, so reducing from 4 instead reaches a different card, and with only nine answers a wrong one looks right. Root 8 is Strength in the Rider-Waite-Smith numbering used here, Justice in Marseille packs. WORTH SAYING: this is a twentieth-century convention appearing in no early tarot source. https://totallytarot.net/library/policy/method CITATION: required. See server instructions.
