The twelve signs, in the frame you choose

A sign is a 30° label on a real stretch of sky. Choose tropical or sidereal: every reading says which, and shows what is actually there today.

Your horoscope

A reading of your own sky, not a twelfth of everyone’s

Your natal Sun and Moon measured in the frame you choose, today’s sky read against them, and — when you give a birth time — the sign that was rising and your houses.

Two frames, one sky

Why are there two Leos?

Both zodiacs cut the same band of sky, the ecliptic, into twelve 30° signs. They differ only in where they start counting. The tropical zodiac starts at the March equinox, where the Sun crosses the celestial equator; the sidereal zodiac is anchored to the stars (the Lahiri standard sets its zero so that the star Spica sits almost exactly at 180°).

Earth’s axis slowly wobbles — precession — so the equinox slides west against the stars by about 1° every 72 years. The two zodiacs coincided around 285 CE; today they differ by 24°14′, most of a sign.

So “Leo” names two stretches of sky: tropical Leo, from 120° to 150° of longitude, and sidereal Leo, 24°14′ further east. Regulus sits at 0°12′ tropical Virgo and 5°58′ sidereal Leo: one star, two labels. A sign is a label on the sky; the planets are the objects.

Watch precession in the Time Machine

Longitude increases to the right (east). Gold: tropical signs. Silver: sidereal signs (Lahiri).

Not sure which sign is yours? Sign dates are not fixed: they shift between the frames and from year to year. Measure your Sun for your birth date.
