How do opposite signs interact in the zodiac?

Opposite signs (180° apart) share a magnetic attraction and complementary perspectives, creating intense growth when balanced.

Is zodiac compatibility scientifically proven?

No — there's no scientific evidence that sun sign alone predicts relationship compatibility. This tool applies astrology's traditional element and modality relationships between signs, which some people find useful for reflection or fun, not a factual prediction.

What are the four elements in zodiac compatibility?

The twelve signs are traditionally grouped into Fire (Aries, Leo, Sagittarius), Earth (Taurus, Virgo, Capricorn), Air (Gemini, Libra, Aquarius), and Water (Cancer, Scorpio, Pisces) — astrology generally considers signs within the same element, or in complementary elements, more naturally compatible.

Does this only compare sun signs, or the full birth chart?

This tool compares sun signs only, which is a simplified starting point. A full astrological compatibility reading (synastry) also considers moon sign, rising sign, and other planetary placements for both people, which this quick comparison doesn't cover.
