We each have a card that rules the decan of our Sun.
The astrological signs have 30 degrees. Those 30 degrees are further divided into three 10 degree segments called decans.
- 00° through 9° 59′ Aries is the 1st decan.
- 10° through 19° 59′ Aries is the 2nd decan.
- 20° through 29° 59′ Aries is the 3rd decan.
This process repeats for all of the other signs.
By looking at the degree of your Sun you can find which decan it is in.
The decan of my Sun is ruled by the 3 of Wands.
