Finding Tarot Signifiers with Astrological Decans
Here’s a very brief tutorial on how to use astro.com to pull up a chart, understand which decans you’re looking at, and look up which cards are associated with those decans.
First, go here and input your birth date information. You’ll need your birth time for an ascendant. Then it will take you to this page.
It’s optional but to get a chart like the one I’ll show - under “Zodiac and houses”, select the “whole sign” house system.
Less optional is under “Display and calculation options”, select “Chaldean decans”.
It’ll bring up a chart like this:
What I’ve circled in red are the “Big Three” - Sun, Moon, and Ascendant. Decans are counted counter-clockwise through the signs.
The Ascendant of this chart is in the first decan of Scorpio - Scorpio I.
The Sun (circle with a dot in it) is in the second decan of Aquarius - Aquarius II.
The Moon (crescent) is in the third decan of Gemini - Gemini III.
Alternatively you can scroll down and use the list format:
The first decan of each sign is 0 degrees - 9 degrees
The second decan is 10 degrees - 19 degrees
The third decan is 20 degrees - 29 degrees
The AC (short for Ascendant) is at 1 degrees Scorpio - so it’s in the first decan.
The Sun is at 12 degrees Aquarius - so it’s in the second decan.
The Moon is at 22 degrees Gemini - so it’s in the third decan.
Finding the cards for the decans:
Queen of Wands - Pisces III, Aries I, Aries II
King of Pentacles - Aries III, Taurus I, Taurus II
Knight of Swords - Taurus III, Gemini I, Gemini II
Queen of Cups - Gemini III, Cancer I, Cancer II
King of Wands - Cancer III, Leo I, Leo II
Knight of Pentacles - Leo III, Virgo I, Virgo II
Queen of Swords - Virgo III, Libra I, Libra II
King of Cups - Libra III, Scorpio I, Scorpio II
Knight of Wands - Scorpio III, Sagittarius I, Sagittarius II
Queen of Pentacles - Sagittarius III, Capricorn I, Capricorn II
King of Swords - Capricorn III, Aquarius I, Aquarius II
Knight of Cups - Aquarius III, Pisces I, Pisces II
Pages vary. Thoth systems tend to align them differently than Rider Waite systems and so many decks are removed from both at this point that it’s often easier to read and see which feels right to you. Some people pair them with the Queens or Kings and others use them to represent the element of the suit - similar to aces. I don’t typically use them as signifiers unless they had a traditional relationship to someone’s work. .
How to figure out which pip corresponds with a decan (Quick Version):
Sagittarius - Mutable, Fire
Capricorn - Cardinal, Earth
Cardinal signs are the 2, 3, and 4 for each suit.
Fixed signs are the 5, 6, and 7, for each suit.
Mutable signs are the 8, 9, and 10 for each suit.
Earth signs are pentacles.
The first decan is the first number and suit in the progression. The second is the second and so on.
Ex: Aries - cardinal (2,3,4), Fire (wands).
If you’d like to know which pip corresponds with the decans. Check out T Susan Chang’s writing on Reading the Decans or her book 36 Decans. It’s a great way to learn both the decans and the pips
So for this chart, the options this person can pick from are:
I hope this makes sense and is helpful to people!
