Zodiac Compatibility Calculator
Pick two signs to see how astrology reads the pair by element, modality and the angle between them. There is no percentage or score: in astrology, compatibility between two signs is a kind of relationship, not a number.
Dates are approximate. If you were born near the edge of a sign, check your Sun sign with the birth chart calculator. Birth chart calculator

How compatibility is read
Astrology reads two signs through three things. First, the element: fire, earth, air and water. Signs of the same element share a temperament, and fire with air, and earth with water, are counted as elements that feed each other. Second, the modality: cardinal signs start things, fixed signs sustain them and mutable signs adapt. Third, the angle between the signs: 120° (trine) and 60° (sextile) are read as flowing, 90° (square) and 180° (opposition) as tense, and 30° and 150° as angles that need adjustment.

Frequently asked questions
Which signs are most compatible?
Astrology reads signs of the same element (for example Aries, Leo and Sagittarius) as the most fluent pairs, joined by a trine; fire and air, and earth and water, are counted as elements that feed each other. Still, no pairing is good or bad on its own: squares and oppositions are linked with growth and attraction as much as with friction.
Does sign compatibility tell me how my relationship will go?
No. It describes how astrology reads two signs; it does not say how a relationship turns out. That is why there is no percentage or score here. Use the result as a starting point for talking about how you see each other.
What else matters besides the Sun sign?
In synastry, the comparison of two full birth charts, astrology also looks at the Moon signs for emotional needs, Venus and Mars for how each person loves and wants, and the rising signs for first impressions. The Sun sign is only one part of that picture.
How do I know my sign?
The list shows each sign's usual dates. The day the Sun changes sign can shift by a day from year to year, so if you were born on a boundary day, the birth chart calculator gives your exact Sun sign.
