Mars Retrograde
Mars Retrograde explains apparent motion, station dates, natal versus transit use, sign changes, chart context, and interpretation limits.
Overview
Signed motion is −0°06′/day, so Mars is retrograde in the sample. This is the worked result for Mars Retrograde; it remains conditional and does not turn geometry or timing into a verdict. The comparison method is explicit: Solve the station loop, opposition, repeated sign degrees, and exact contacts to natal bodies; retain separate ingress and egress dates. Mars retrograde is an interval of apparent backward motion measured from the geocentric longitude stations. The sign containing a retrograde changes by date, so a reference to Mars in Leo or any other sign belongs to a dated calendar rather than an evergreen definition. A natal Mars retrograde and a current transit are separate calculations, and neither proves anger, delay, conflict, or loss of drive.

Definition and exact scope
Mars retrograde is a station-to-station interval of apparent backward geocentric motion near opposition.
Calculation or decision rule
Solve the station loop, opposition, repeated sign degrees, and exact contacts to natal bodies; retain separate ingress and egress dates. The receipt retains the chosen input record, reference frame, tolerance, and version, then identifies the first step where an independent recalculation diverges.
Calculate Mars retrograde dates from the sign of its geocentric longitude speed and solve the two station instants under one ephemeris and time standard. Record sign ingresses separately and label optional shadow periods as a different convention. For a natal reading, first verify that the birth instant falls inside the measured interval, then inspect sign, house, aspects, and chart-wide repetition. Do not reuse a dated Leo or other sign example as a timeless rule.
Worked case and illustrative near miss
♂ 7°20′ at t0 and 7°14′ at t0+24h; zodiac crossing already unwrapped. signed motion is −0°06′/day, so Mars is retrograde in the sample.
Illustrative near miss; does not qualify: Treating slower direct motion as retrograde because the daily speed is below average but still positive.
School, model, and context variants
Mars retrograde is not evidence that action must stop, conflict is inevitable, or injury will occur.
