Cardology compatibility compares two people's cards to show how they relate. Every card has fixed positions in cardology's spreads, and the planetary link between two cards (Venus, Mars, Saturn, and so on) describes the dynamic between the people who hold them. You only need both birthdays.
How it works
Each card sits in two spreads: the Earth Path, which covers everyday life, and the Heaven Path, which covers the deeper, spiritual side. When one person's card shows up among the other person's planetary cards, that planet names the connection. (Destiny Cards Relationship Chart →)
The main connections
| Connection | What it feels like |
|---|---|
| Moon | Comfort and emotional safety |
| Venus | Affection and attraction |
| Mars | Chemistry, drive, and some friction |
| Jupiter | Generosity and good luck |
| Saturn | Lessons, responsibility, staying power |
| Uranus | Freedom and surprise |
| Neptune | Idealism and deep, dreamy love |
How the suits get along
- ♥ Hearts want emotional closeness.
- ♣ Clubs want conversation and ideas.
- ♦ Diamonds want shared values and security.
- ♠ Spades want loyalty and a shared purpose.
Different suits often balance each other: a Club's ideas land well with a Diamond who likes to build.

Three cards, not one
Most compatibility guides compare one card per person. Cardy compares all three: how your instincts mix (Inner Child), whether your goals line up (Chosen Purpose), and what you bring out in each other (Highest Self). A bumpy first-card match can still be strong across the other two.
Cardology compatibility FAQ
Can any two cards work?
Yes. Cardology doesn't label couples incompatible. It shows where the strengths and the friction are.
What's the strongest connection?
Venus links and karma-card links tend to feel the most magnetic.
How is it different from astrology compatibility?
Astrology compares whole charts and the angles between planets. Cardology finds direct links between cards using only birthdays.
