Mars in each sign
Mars spends about six to seven weeks in a sign, so your birth date is almost always enough. On the day it changed sign, the time decides.
Mars in Aries: The direct force
Mars rules Aries, so your drive is strong and immediate. You act first, compete openly and recover fast. Anger flares and fades quickly. You do best with clear goals, physical outlets and room to lead. Waiting is your weak spot; starting things is your strength.
Mars in Taurus: The unstoppable force
You move slowly and do not stop. Once you commit to something, little can shift you. You are hard to provoke and formidable when you are. You work best at your own pace, with a tangible result in sight. Being hurried makes you dig in.
Mars in Gemini: The quick force
You act through words and ideas. You fight with arguments, juggle several projects and get bored when one task drags. Your energy comes in bursts. Variety and mental challenge keep you motivated, and a sharp debate is your idea of a good contest.
Mars in Cancer: The protective force
You act on feeling, and you fight hardest for the people you love. Your approach is indirect: you sense the situation before you move. Anger can be held in and come out sideways. You are at your strongest defending home, family or anyone vulnerable.
Mars in Leo: The proud force
You act with confidence and want your efforts to be seen. You lead naturally and put your whole heart into what you do. Pride drives you and can make you stubborn. You work best when you believe in the goal and are recognised for reaching it.
Mars in Virgo: The precise force
You put your energy into doing things properly. You work methodically, improve as you go and are tireless with a useful task. Anger shows as criticism. You are motivated by competence and by being useful, and you do your best work behind the scenes.
Mars in Libra: The strategic force
You act through people and prefer to win by persuasion. You fight for fairness, often on someone else's behalf, and avoid open conflict until a line is crossed. Decisions can take time. You work best with a partner or a team.
Mars in Scorpio: The intense force
Mars is traditionally strong in Scorpio, so your drive is deep and determined. You act privately, strategically and completely. You do not forget a slight, and you do not give up. Your energy is best spent on goals that matter to you, which you pursue to the end.
Mars in Sagittarius: The adventurous force
You act on enthusiasm and belief. You need a cause, a challenge or a horizon to aim at, and you take big risks for them. Anger is quick and honest. Routine drains you; freedom, sport and travel recharge you.
Mars in Capricorn: The disciplined force
Mars is exalted in Capricorn, so your drive is controlled and ambitious. You plan, persist and climb. You are patient with long goals and impatient with waste. Anger is cold and measured. You are at your best building something that will last.
Mars in Aquarius: The independent force
You act on principle and in your own way. You fight for causes, groups and ideas more than for yourself. You resist being told what to do. Your energy works best on original projects and with people who share a purpose.
Mars in Pisces: The flowing force
You act on intuition and feeling rather than plans. Your energy rises and falls with your mood and the people around you. You avoid direct conflict and can be worn down by it. You are motivated by compassion, art and causes that help others.
What your Mars sign tells you
Mars is the planet of action. Its sign shows how fast you move, how you compete, what motivates you and how you behave in a fight. Where Venus attracts, Mars pursues.
Your Mars sign is useful for understanding what kind of work and exercise suit you, and why some arguments escalate and others never start.
