How to Calculate Your Birth Card in Tarot

Determining your birth card in tarot is a fascinating way to connect with your personal energy and life path. This guide explains the calculation process using the Julian day method, which is widely used in tarot readings. By following these steps, you'll discover which tarot card represents your birth date and gain insights into its meaning.

What is a Birth Card in Tarot?

A birth card in tarot is a single card that represents your life's purpose, core energy, and fundamental nature. It's determined by your birth date and is often used in tarot readings to provide a starting point for understanding yourself and your life journey.

The concept of birth cards is based on the idea that each day of the year corresponds to a specific tarot card. This creates a cyclical pattern that repeats every 22 years (since there are 78 tarot cards and 22 major arcana cycles).

Note: The tarot deck used for birth cards typically includes the 78-card Rider-Waite-Smith deck, which contains the 22 major arcana and 56 minor arcana cards.

How to Calculate Your Birth Card

Calculating your birth card involves several steps that transform your birth date into a specific tarot card. Here's the step-by-step process:

Step 1: Convert Your Birth Date to Julian Day

The first step is to convert your birth date into a Julian day number. This involves:

Determining the day of the year (1-365 or 1-366 for leap years)
Adding 1 to account for the fact that January 1 is day 1

Formula: Julian Day = Day of the year + 1

Example: If you were born on February 15 (non-leap year), the day of the year is 46, so the Julian day is 47.

Step 2: Calculate the Major Arcana Cycle

Next, determine which major arcana cycle your birth falls into. There are 22 major arcana cards, so we'll use modulo 22 arithmetic to find the position in the cycle.

Formula: Major Arcana Position = (Julian Day - 1) % 22 + 1

Example: For Julian day 47, (47 - 1) % 22 = 46 % 22 = 4, so the major arcana position is 5.

Step 3: Determine the Birth Card

The major arcana position corresponds to a specific major arcana card in the Rider-Waite-Smith deck. Here's the sequence:

Position	Major Arcana Card
1	The Fool
2	The Magician
3	The High Priestess
4	The Empress
5	The Emperor
6	The Hierophant
7	The Lovers
8	The Chariot
9	Strength
10	The Hermit
11	Wheel of Fortune
12	Justice
13	The Hanged Man
14	Death
15	Temperance
16	The Devil
17	The Tower
18	The Star
19	The Moon
20	The Sun
21	Judgement
22	The World

Using our example, position 5 corresponds to The Emperor.

Example Calculation

Let's walk through a complete example to calculate a birth card. We'll use the birth date of January 15, 1980.

Step 1: Convert to Julian Day

January 15 is day 15 of the year, so the Julian day is 15 + 1 = 16.

Step 2: Calculate Major Arcana Position

(16 - 1) % 22 = 15 % 22 = 15, so the major arcana position is 15 + 1 = 16.

Step 3: Determine Birth Card

Position 16 corresponds to The Devil in the Rider-Waite-Smith deck.

Result

For someone born on January 15, 1980, the birth card is The Devil.
