What is a Mars sign?

Your Mars sign is the zodiac sign the planet Mars occupied at your birth. In astrology, Mars rules drive, desire, ambition, anger and raw energy — it describes how you pursue goals, how you fight, how you compete, and what ignites your passion. Where Venus shows how you love, Mars shows how you want. It's essential for understanding your work style, conflict style and physical chemistry. Mars spends about six to seven weeks in each sign, so your birth date alone gives an accurate result in nearly every case.
