The 12 Mars signs

How the Mars sign relates to your Sun sign

Mars usually stays in a sign for about 6 to 7 weeks; around its retrograde (about every 26 months) it can stay in one sign for several months (up to about 8). Unlike Venus and Mercury it is not tied to the Sun, so your Mars sign can be any sign.

Each sign page lists every period Mars spent in that sign from 1940 to 2030, with ingress times. If your birth date falls inside a period, that is your Mars sign. If you were born on a changeover day, enter your birth time in the calculator above.

What does the Mars sign mean?
In Western astrology the Mars sign describes drive, desire, competitiveness, anger and attraction. It is read as a separate layer from the Sun sign (will and direction) and the Moon sign (feelings).
Can my Mars sign differ from my Sun sign?
Mars usually stays in a sign for about 6 to 7 weeks; around its retrograde (about every 26 months) it can stay in one sign for several months (up to about 8). Unlike Venus and Mercury it is not tied to the Sun, so your Mars sign can be any sign.
Do I need my birth time?
