The ruling planet for Aries is Mars. Mars is the planet of action, drive, passion, and energy, which makes perfect sense given Aries intense and passionate energy. Mars gives Aries the courage to be a warrior in life and fuels them to be an unstoppable force and create the life that they envision. During Aries season, which lasts from approximately March 21 to April 19 each year, we all feel Mars influence.
