Sidereal vs. tropical astrology: what’s the difference?

two ways of measuring the same sky

Wondering why your sign may look different here? Tropical and sidereal astrology measure the zodiac from two different starting points — and today they’ve drifted about 24° apart.

Western tropical

Anchors 0° Aries to the spring equinox and moves with the seasons — the system most of us grew up with.

Sidereal

Anchors the zodiac to the actual stars and accounts for precession, the slow shift in Earth’s orientation over time.

Neither is wrong — they’re two lenses on the same sky.

This calculator uses sidereal astrology, so your Sun, Moon, or Rising may fall in the sign before the one you know.
