What is Cardstrology?
Your birthday already belongs to a card. One of 52, fixed before you arrived.
The deck is a calendar. 52 cards, 13 values, four suits, 52 weeks. The math was always there.
We read that card against your Sun, Moon, Rising, and Venus. Two old systems, one person.
It does not tell you what happens. It shows you what you are standing in. The rest is yours.
