Why do you have zodiac?

Answer 1

The constellations associated with the zodiac signs are in a belt formation around the Earth on the celestial sphere. They were originally used to forecast the influence they had on events and people on Earth; especially the seasons. In the northern hemisphere the Sun entering Aries occurs with the Vernal / spring equinox. the start of spring. The Sun entering Cancer with the summer solstice; Sun entering Libra with the autumn equinox and the Sun entering Capricorn the winter solstice.

Due to the precession of the equinoxes the zodiac signs and the constellation no longer align; the Sun is now in the constellation Pisces when it enters the zodiac sign Aries at the vernal equinox.
