Lunar Return

A lunar return is the recurring instant when the transiting Moon reaches the natal Moon’s chosen zodiac longitude. Scope is explicit.

Overview

One lunar-longitude crossing is interpolated inside the bracket; the fast Moon requires timestamp precision. This is the worked result for Lunar Return; it remains conditional and does not turn geometry or timing into a verdict. The comparison method is explicit: Use a fine time step to solve the fast lunar crossing, state true apparent position and zodiac choice, then calculate angles only for a declared location.

Definition and exact scope

A lunar return is the recurring instant when the transiting Moon reaches the natal Moon’s chosen zodiac longitude.

Calculation or decision rule

Use a fine time step to solve the fast lunar crossing, state true apparent position and zodiac choice, then calculate angles only for a declared location. The receipt retains the chosen input record, reference frame, tolerance, and version, then identifies the first step where an independent recalculation diverges.

Worked case and illustrative near miss

natal ☽ 22°40′♋; transit bracket 22°35′ to 22°47′; hourly samples. one lunar-longitude crossing is interpolated inside the bracket; the fast Moon requires timestamp precision.

Illustrative near miss; does not qualify: Reusing a monthly calendar date while the Moon has not returned to 22°40′ Cancer.

School, model, and context variants

A monthly return chart is not a deterministic monthly calendar, and a birth-time error can shift the natal Moon and every return timestamp.

Product, safety, and verification boundary
