Mars Return
Mars Return explains its meaning, approximate two-year cycle, exact natal-longitude calculation, retrograde repeat dates, return chart, and limits.
Overview
Mars is 0°15′ from natal longitude; one return chart is tied to exactitude. This is the worked result for Mars Return; it remains conditional and does not turn geometry or timing into a verdict. The comparison method is explicit: Bracket and solve every longitude equality, note station proximity and multiple crossings, then keep return-chart location separate from the natal birthplace. A Mars return occurs when transiting Mars reaches the same geocentric zodiacal longitude as natal Mars. It is often summarized as an approximately two-year cycle, but the actual dates require an ephemeris, and retrograde motion can create more than one exact crossing. Astrologers may use the return chart to organize questions about initiative, effort, conflict response, desire, and recovery; the return does not cause or predict injury, anger, sex, competition, career action, or a compulsory fresh start.

What is a Mars return, and how often does it happen?
A Mars return is the exact return of transiting Mars to natal Mars longitude, on an irregular interval shaped by retrograde motion.
How to calculate exact Mars return dates
Bracket and solve every longitude equality, note station proximity and multiple crossings, then keep return-chart location separate from the natal birthplace. The receipt retains the chosen input record, reference frame, tolerance, and version, then identifies the first step where an independent recalculation diverges.
Record the natal Mars longitude, zodiac, ephemeris, birth-time source, and numerical tolerance. Search a wide interval around the approximate two-year recurrence. Compute a continuous, unwrapped transiting-minus-natal longitude difference, bracket its true zero crossings, and verify each solution has a shortest angular separation near 0°; do not treat the ±180° wrap discontinuity, calendar birthday, or same-sign transit as a return. Label direct and retrograde passes separately. If a return chart is cast, use the exact crossing time and a declared location, then compare its Ascendant, Mars house, close aspects, and natal-chart contacts. Keep one exact return distinct from the longer Mars transit cycle and test symbolic themes against dated behavior.
Illustrative near miss: approximate cycle without an exact crossing
natal ♂ 24°10′♏; transit ♂ 23°55′♏; return cap 0°30′. Mars is 0°15′ from natal longitude; one return chart is tied to exactitude.
Illustrative near miss; does not qualify: Using the approximate two-year cycle without calculating the natal longitude crossing.
Return chart, retrograde repeat, and location choices
A Mars return does not predict conflict, injury, athletic victory, sexual activity, or a compulsory new beginning.
What a Mars return cannot predict
