How to Calculate Your Tarot Birth Cards
Use a Gregorian date. This free tarot birth card calculator follows The Tarot School’s published formula. It requires no account, name, birthplace or birth time.
- Add the month, day, first two year digits and last two year digits: MM + DD + CC + YY.
- For a two-digit total, add its digits. For a three-digit total, add the first two digits as one number to the last digit. If the result exceeds 21, reduce again.
- Keep a two-digit card and reduce it to its companion. A single digit receives its implied partner. Preserve 19 → 10 → 1 as three cards.
Example 1: an ordinary pair
February 21, 1950: 02 + 21 + 19 + 50 = 92, then 9 + 2 = 11, and 1 + 1 = 2. The combination is Justice (11) and The High Priestess (2).
Example 2: a single-digit result
January 1, 2000: 01 + 01 + 20 + 00 = 22, then 2 + 2 = 4. Its implied partner is 4 + 9 = 13: Death (13) and The Emperor (4). This method does not assign 22 to The Fool.
Example 3: three birth cards
March 7, 1980: 03 + 07 + 19 + 80 = 109, then 10 + 9 = 19, 1 + 9 = 10, and 1 + 0 = 1. Keep The Sun (19), Wheel of Fortune (10) and The Magician (1).
For another three-digit check, August 20, 1969 gives 116 → 17 → 8: The Star and Strength. The initial reduction matters: January 1, 1900 totals 21, which first reduces to 3 and receives the implied 12/3 pair. A later reduction reaching 21 gives 21/3 instead.

Why Tarot Birth Card Results Can Differ
The method label is part of your result. Adding all birthday digits individually, adding the whole year, or choosing different companion rules can produce another combination. The Tarot School acknowledges that methods differ; its formula is one convention, not a universally agreed or scientifically validated answer.
This page uses Strength = 8, Justice = 11, and no Fool birth card. Single digits 2 and 3 receive 11 and 12 respectively; a reduction that reaches 20 or 21 retains that group. You can compare the displayed arithmetic with another tool before comparing its interpretation.
