Unlike simple sun sign compatibility, our AI-powered calculator analyzes complete birth charts including Moon signs, Venus and Mars positions, house overlays, and planetary aspects.

Frequently Asked Questions

What zodiac signs are most compatible?

Generally, signs of the same element have natural compatibility: Fire signs (Aries, Leo, Sagittarius), Earth signs (Taurus, Virgo, Capricorn), Air signs (Gemini, Libra, Aquarius), and Water signs (Cancer, Scorpio, Pisces). However, true compatibility depends on your complete natal chart — Moon signs, Venus placements, and house overlays matter just as much as Sun signs.

What is synastry in astrology?

Synastry is the astrological technique of comparing two natal charts to assess relationship compatibility. It examines how one person's planets aspect (interact with) the other person's planets. Key factors include Venus-Mars connections (attraction), Moon aspects (emotional bond), and Sun-Moon contacts (core compatibility). Our AI analyzes all synastry aspects automatically.

How does zodiac compatibility actually work?

Zodiac compatibility works by analyzing how planetary positions in two birth charts interact. Harmonious aspects (trines, sextiles) indicate natural ease, while challenging aspects (squares, oppositions) show areas of tension and growth. The AI examines Sun, Moon, Venus, Mars, and all planetary interactions across houses to calculate an overall compatibility profile.

Can incompatible zodiac signs make a relationship work?

Absolutely. So-called 'incompatible' signs can build strong relationships. Challenging aspects create passion and growth opportunities. What matters most is awareness and communication. Many successful couples have difficult synastry — they simply understand their differences and work with them. Use compatibility insights as guidance, not a verdict.

What is the most accurate compatibility test in astrology?

The most accurate compatibility analysis uses full synastry chart comparison — not just Sun signs. This requires both partners' birth date, time, and location to calculate complete natal charts. Our AI then compares all planetary aspects, house overlays, and composite chart patterns. This is far more accurate than simple Sun sign matching used by most compatibility quizzes.
