The 12 zodiac signs at a glance
- Twelve signs split the tropical zodiac into 30° each, anchored to the seasons, not the constellations.
- Each sign has a fixed element (fire, earth, air, water), a modality (cardinal, fixed, mutable) and a ruling planet.
- Dates shift by a day year to year because the Sun's ingress is an astronomical instant, not a calendar rule.

How the four elements and three modalities map
The four elements repeat in the same order around the wheel: fire, earth, air, water, starting at Aries. Signs sharing an element sit 120° apart and form a triangle, called a trigon.
The three modalities also repeat — cardinal, fixed, mutable — starting at Aries. Cardinal signs open each season (Aries/spring, Cancer/summer, Libra/autumn, Capricorn/winter in the northern hemisphere), fixed signs hold its middle, and mutable signs transition out of it.
Because every sign has exactly one element and one modality, the pair is unique: there is only one cardinal-fire sign (Aries), one fixed-earth sign (Taurus), and so on.
Classical vs modern rulers
Before the outer planets were discovered, each of the seven classical planets ruled either one or two signs, with the Sun and Moon ruling one each. That scheme is still used in traditional and Hellenistic astrology.
Modern Western astrology reassigned Scorpio to Pluto, Aquarius to Uranus, and Pisces to Neptune after those planets were found (1781–1930). Both rulers are shown above so the table is usable in either tradition.
