Mars sign calculator: what is my Mars sign?
Your Mars sign is the zodiac sign Mars was in when you were born. Mars changes sign about every six to seven weeks, so your birth date settles it and your birth time makes it exact. This free Mars sign calculator gives you the answer first, then your Sun, Moon and rising sign.
You need your birth date and your birth place. Add your birth time to make it exact. Mars lingers in a sign for weeks, so the date alone usually decides it, and the tool flags any day the sign changed.
What each mars sign means
How you push and act. These are tendencies, not rules.
- Aries
- You tend to act first and think it through on the way. Your temper flashes and clears quickly.
- Taurus
- You tend to work slowly, build steadily and refuse to be hurried. You dig in when pushed.
- Gemini
- You tend to get things done with words and ideas, many at once. Your sharpest line can land harder than you mean.
- Cancer
- You tend to push hardest for other people and go indirect with your own wants.
- Leo
- You tend to work boldly and want to be seen doing it. Pride can turn a small knock into a scene.
- Virgo
- You tend to work carefully to a high bar. Your own critic is the harshest one you know.
- Libra
- You tend to win by negotiating rather than fighting. You avoid the clash until it grows bigger than it needed to be.
- Scorpio
- You tend to go quiet, aim hard and commit fully. You can hold a grudge longer than is good for you.
- Sagittarius
- You tend to take the big leap and keep your options open. Small, steady steps bore you.
- Capricorn
- You tend to grind, plan and play the long game. You go cold rather than loud when angry.
- Aquarius
- You tend to fight for the idea or the group. You stay cool, and you can walk away when it turns emotional.
- Pisces
- You tend to act on instinct and slip around obstacles. Saying a clean no is the hard part.
Common questions
- What is a Mars sign?
- Your Mars sign is the zodiac sign Mars was in at the moment you were born. It is often described as how you go after what you want, how you compete and how your anger shows up.
- Do I need my birth time for my Mars sign?
- Rarely. Mars spends about six weeks in a sign, so your birth date almost always gives the right one. When Mars changes sign on your birth day you need the time, and this tool tells you if that is your case.
- What does the Mars sign affect?
- Mars is about drive, action and anger. It is separate from your Sun sign, which is about your core identity, and your Moon sign, which is about how you feel and what settles you.
- Is this Mars sign calculator free?
- Yes. It is free. There is no account, no email and no sign up. Natus is the journaling app behind it, and the First Reading in the app is free too. Your birth date, time and chart are worked out inside your browser. They are not sent to us and they are not saved. Only the place name you type goes to Open-Meteo, a free map lookup, so we can find its coordinates and time zone.
- How accurate is it?
- Planet positions come from the same astronomy code the Natus app uses, and we test it against reference charts from astro.com. Signs and degrees are exact. The rising sign is only as good as your birth time, because four minutes of time moves it about one degree. Houses use the whole sign system. Sites that use another system, like Placidus, can give a different house number for the same planet. The signs stay the same.
