Mars governs drive: what you chase, how you chase it, what you do with anger, and what desire feels like in your body. In relationship astrology it is read as the partner placement to Venus, Venus is the love style, Mars is the want. The classic compatibility check pairs one person's Venus with the other's Mars. Find your other half of that equation with the Venus sign calculator.
Why date is enough
Mars changes signs roughly every six to seven weeks, so a birth date pins it for almost everyone. If your Mars sits within a degree of a boundary, the calculator flags it.
