Zodiac

The signs run in a fixed order: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces. Each owns thirty degrees, and twelve times thirty makes the full 360 of the circle. Western astrology uses the tropical zodiac, which pins zero degrees of Aries to the point where the Sun crosses the equator at the March equinox. Because of that anchor, the signs track the seasons rather than the star patterns behind them.

The constellations of Aries, Taurus and the rest still sit in the sky, but they no longer line up with the signs of the same name. The Earth wobbles slowly on its axis, a motion called precession that drifts the equinox point about one degree every seventy-two years. Over two thousand years that gap has grown by roughly a full sign. The tropical zodiac ignores the drift and stays tied to the seasons; the sidereal zodiac used in Vedic astrology keeps step with the constellations instead.

Traditionally the sign a planet sits in describes the style of that planet. The same Mars reads as blunt and quick in Aries and as patient and stubborn in Taurus. Signs are sorted into four elements and three modalities, and those groupings are a fast way to read the overall flavor of a chart.

Every year the Sun enters Aries at the March equinox. In 2026 that crossing fell on 20 March, so a birthday on 19 March is the tail of Pisces and one on 21 March is early Aries. Anyone born within a few hours of the boundary needs an exact birth time to settle which sign the Sun was in.

The biggest is treating the signs as the visible constellations, a link precession broke long ago. People also confuse signs with houses, since both come in twelves. Signs are fixed bands of the zodiac, while houses are pinned to your birth time and place.
