Aries — The Ram

Fire Cardinal Ruled by Mars Mar 21 – Apr 19

The first sign of the zodiac, Aries opens the astrological year as spring begins. As a cardinal fire sign ruled by Mars, it is traditionally read as active and initiating — the energy that starts things moving. In astrology it is linked to boldness, courage, and independence, with a pioneering drive to go first. Tradition paints it as direct and enthusiastic, happiest when it has something new to begin.
