Mars Sign Calculator: How You Love
Your Mars sign is the sign Mars stood in on the day you were born, and it describes what you go after rather than what you like. It sets how you pursue somebody, how fast you move, what you do when you are refused, and what your anger looks like on the way out. Mars is slow enough that your birth date settles it.
What this Mars goes after
Venus decides who you fall for. Mars decides what you actually do about it, which is a different question and the one that usually breaks things.
Mars is appetite and initiative — the planet of going after. In a chart read for love it answers the practical half nobody puts in a dating profile. Do you make the first move or engineer a situation where the other person has to? How fast do you want to move once you have decided? What happens when you are refused, or kept waiting, or told not now? And when you finally lose your temper, does it arrive in four seconds or four months, and does it leave?
It is also the placement that decides pace, and pace is what most early relationships die of. Two people can want the same thing and want it at speeds two months apart, and neither of them will describe the problem that way. One will say the other was intense. The other will say they were being messed about.
Mars is not the aggressive part of you and reading it as anger alone wastes it. It is the part that wants something enough to cross a room.
Why a date is always enough for Mars
Mars covers about half a degree a day, which is slower than the Sun and roughly twenty-five times slower than the Moon. It sits in one sign for six to eight weeks, so unless you were born inside the few hours it changed sign, the date is the whole answer and the hour changes nothing.
Every couple of years it goes retrograde and the arithmetic gets stranger rather than harder. A retrograde loop can hold Mars inside a single sign for as long as seven months — Mars was in Gemini from August 2022 to March 2023 — so people born a whole season apart can share the placement. If you have ever noticed that everyone born in a particular stretch seems to fight the same way, this is that.
So unlike the Moon, Mars is not an argument for finding your birth time. It is the one of the three you can have for free.
How to find yours
Enter the date you were born. That is all this needs, and nothing is stored.
If you were born on one of the rare days Mars crossed a boundary, this page names both signs rather than choosing the flattering one. Mars also turns retrograde for about two months every two years, and a retrograde Mars does not change your sign: it describes somebody whose drive runs inward before it runs outward, who is slow to start a fight and unnervingly hard to stop once started, and who has to want something privately for a long time before anybody else finds out.
With a birth time and place, the full chart adds the house Mars sits in — the area of life where all this energy actually goes — plus the aspects it makes to your Venus and Moon, and the card ruling its exact degree.

Questions people ask
Do I need my birth time to find my Mars sign?
+
Almost never. Mars spends six to eight weeks in a sign, so a date settles it except on the single day it changes over — and this page tells you when that day is yours instead of picking a side.
What is the difference between Venus and Mars in a chart?
+
Venus is what attracts you and Mars is what you do about it. Venus picks the person; Mars sets the pace, makes the move, and runs the argument. They disagree in most charts, and that disagreement is why somebody can be drawn to calm people and pursue them like a campaign.
Does Mars only describe anger?
+
No, and reading it that way throws away the useful part. Mars is appetite and initiative — how you go after anything you want. Anger is simply the most visible thing it does when the going-after is blocked.
What does a retrograde Mars mean in a birth chart?
+
It does not change your sign. It describes drive that runs inward first: wanting things privately and for a long time before acting, hesitating at the start of a confrontation, and being remarkably difficult to stop once you have finally committed to one.
What is the card for my Mars?
+
Every ten degrees of a sign is a decan, and in the Golden Dawn tradition each decan is ruled by a minor arcanum. So your Mars is not only in a sign, it sits on one of three cards — and which one depends on the exact degree, which the full chart works out.
