Definition
A band around the ecliptic used in astronomy and divided into signs in astrological systems.
Why it matters
The zodiac is a way of organizing positions along the ecliptic. Astrology commonly divides it into twelve 30° signs, while astronomy also uses the term when discussing the constellations along the ecliptic.
Example
The tropical zodiac begins Aries at the March equinox, while sidereal systems use a stellar reference and an ayanamsa.
Common confusion
“Zodiac sign” and “zodiac constellation” are related terms but not identical. Astrological signs are equal 30° divisions; astronomical constellations have unequal boundaries.
