👉 The term "zodiac" is a term used to describe an animal sign, or one of twelve signs of the zodiac. The zodiac is a system that divides the human calendar into 24 equal parts called "zodiacal days," and each day corresponds to a different aspect of life, such as love, wealth, or health. The zodiac is often used in astrology, which is a branch of astronomy that studies the movements of the sun, stars, and planets.
