What is a Mars sign?
Mars in your natal chart
Your Mars sign is the zodiac sign Mars occupied at birth. Mars moves much more slowly than the Moon and usually remains in a sign for several weeks.
Sign, degree, and retrograde
The sign describes style, the exact degree places Mars precisely, and retrograde status records whether Mars appeared to be moving backward from Earth's viewpoint at your birth.
Context changes expression
Mars does not determine behavior by itself. Its house, aspects, and relationship with Venus, Saturn, Pluto, and the chart ruler show where and how its drive is supported, redirected, or challenged.

Questions, answered
Mars Sign Calculator FAQ
What does my Mars sign mean?
It describes your style of action, pursuit, motivation, assertion, anger, and desire. It is a tendency and symbolic pattern, not a verdict about behavior.
Is Mars sign important for compatibility?
Mars can describe pursuit, chemistry, and conflict style, but meaningful compatibility also depends on the Moon, Venus, Mercury, angles, houses, and cross-chart aspects.
Do I need a birth time to calculate Mars?
Mars usually stays in one sign for weeks, so a date often identifies the sign. Exact time removes ambiguity on an ingress day and is necessary for a reliable house placement.
What does Mars retrograde mean in a birth chart?
Natal Mars retrograde is traditionally interpreted as a more internal or self-directed relationship with assertion and anger. It does not mean weak motivation or predict conflict.
