Enter two birth dates to see how your charts interact.
Zodiac compatibility is the art of reading how two people's sun signs fit together. Every sign carries an element — fire, earth, air, or water — and a modality that shapes how it moves through the world. When you compare two signs, you're really comparing those underlying temperaments: how each one loves, argues, communicates, and grows.
This calculator does that comparison for you. Enter two birth dates and it finds each person's sun sign, then scores the pairing across love, friendship, and communication — telling you where the connection flows naturally and where it asks for patience. Same-element pairs tend to share a rhythm, complementary elements balance each other out, and clashing ones bring the kind of friction that can deepen a bond or wear it down.
Sun-sign compatibility is the fastest way to take a relationship's temperature, but it's only the first layer. Your Moon, Venus, and Mars placements add the emotional, romantic, and physical detail that a full birth chart reveals. Use the free score above, then explore any specific pairing for a deeper read.
Pick two signs to jump straight to their breakdown of love, friendship, and communication — all 78 pairings are covered.
Each sun sign belongs to an element (fire, earth, air, water) and a modality (cardinal, fixed, mutable). Compatibility looks at how two signs' elements and modalities interact — same-element pairs share a natural rhythm, complementary elements balance each other, and clashing ones create friction that can become either tension or growth. The calculator turns that interaction into a single score across love, friendship, and communication.
Yes. Enter two birth dates and you'll get a full compatibility breakdown — score, relationship dynamics, and where the pairing flows or needs work — with no sign-up and no payment.
No. This tool reads compatibility from sun signs, which only need a birth date. Birth time matters for a full natal-chart synastry reading, but for a quick sun-sign compatibility check, the date is enough.
As a starting point, signs that share an element (for example two fire signs) or sit in compatible element families tend to score higher, while square and opposite signs face more friction. But sun sign is only one layer — Moon, Venus, and Mars placements often matter more in a real relationship.
Yes — two of the same sign share instincts and values, which can feel effortless, though it can also amplify shared blind spots. Open any pairing below, including same-sign matches, to see how it plays out.
