Green Flags are supportive relational indicators that show where synastry creates ease, resonance, and constructive flow. They highlight natural compatibility, emotional coherence, and mutual uplift across all relationship types.
Why Mars Matters
Mars governs drive, initiative, desire, and the instinct to act. In synastry, it shows how two people energize one another — where motivation rises, where momentum builds, and where shared action feels natural. When someone’s Mars touches a part of your chart, that area tends to feel activated, engaged, and alive with forward movement.
Mars’s Timing
Mars spends about six to seven weeks in each zodiac sign, except during retrograde periods, when it can linger for several months. This makes Mars overlays moderately common — more personal than Jupiter or Saturn, but less fleeting than Venus or Mercury. Mars synastry often shows up as shared momentum, mutual motivation, or a sense of “we get things done together.”
