Decans
Not only can you rep your Sun sign. You can rep your decan sign. Yep, decans. Each sign is split up into 3 decans based on the 30 degrees of a sign. This means that not only does your Sun have a planetary ruler, but you also have a sub-ruler planet that can be used to see an extra influence to your Sun sign traits. The sub-ruler planet will be one of the other two planets that rules the sign in your element. If you are a Virgo, your sub-ruler can only be Mercury (which already rules you), Venus (which rules Taurus), or Saturn (which rules Capricorn).
For example, Mars rules Aries. However, if you were born on April 18th, you are third decan Aries sub-ruled by Jupiter. This brings forth a different Aries individual who may feel they are more on a quest or journey to see how they can spread their influence. This could be a spiritually aware Aries individual as well.
