Overview

The return instant is the interpolated solar-longitude crossing, then one chart is cast for that instant. This is the worked result for Solar Return; it remains conditional and does not turn geometry or timing into a verdict. The comparison method is explicit: Solve longitude equality at high precision, declare tropical or sidereal mode, location policy, precession option, ephemeris version, and comparison with the natal chart.

Definition and exact scope

A solar return is calculated for the instant the transiting Sun returns to its natal ecliptic longitude, usually once per tropical year.

Calculation or decision rule

Solve longitude equality at high precision, declare tropical or sidereal mode, location policy, precession option, ephemeris version, and comparison with the natal chart. 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 ☉ 10°15′♉; transit bracket 10°10′ to 10°20′; location policy declared. the return instant is the interpolated solar-longitude crossing, then one chart is cast for that instant.

Illustrative near miss; does not qualify: Using the birthday at 00:00 local time without solving the Sun’s return.

School, model, and context variants

The calculated return moment is reproducible, but it does not guarantee a year’s events; relocation choice and school rules can change houses and angles.

Product, safety, and verification boundary
