Mars sign calculator
Your Mars sign is the sign Mars was in when you were born. It describes your drive and energy: how you go after what you want, how you compete, how you react when you are angry and what excites you physically.
Mars spends about six weeks to two months in a sign, and much longer when it turns retrograde every two years or so. That is why people born months apart can share the same Mars sign.
Your birth date is enough for the calculation. If Mars changed sign on the day you were born, you will be told the time of the change; adding your birth time settles it.
