Forming means the orb decreases as life-arc advances; separating means it widens. Sorting remains strictly by absolute orb.

Seconds-enabled Janus values are used throughout, including a fresh MD ÷ SA calculation from the unrounded MD and SA. Minute-only specula remain supported, with their unavoidable source-rounding caveat.

Paste the complete Janus speculum, select the event date,
then calculate. Direct and converse results will be interleaved by orb.

Method and fixed rules

Planetary factors. Right ascension is recovered from the Janus OA/OD pair. For seconds-enabled data, MD / SA is recalculated from the full MD and SA rather than the displayed four-decimal ratio. The Kühr proportional pole is then calculated as tan p = (MD / SA) × tan φ, followed by sin ADp = tan p × tan δ. Eastern factors use OA = RA − ADp; western factors use OD = RA + ADp.

Angles and cusps. Their 30°-spaced ascensional coordinates are advanced or regressed with the same primary arc. The Topocentric cusp pole is reconciled to the pasted natal cusp position, RAMC, obliquity, and terrestrial latitude before the directed longitude is recovered.

Timing. primary arc = elapsed calendar days × 0.00269861°. No event-date ephemeris is consulted.

Aspects and phase. 0°, 30°, 45°, 60°, 90°, 120°, 135°, 150°, 180°. The comparison is strictly less than 12′ for conjunction/opposition and strictly less than 6′ for every other aspect. Forming/separating is determined by advancing chronological life-arc slightly; converse directions retain their negative rotational sign while their arc magnitude increases with age.
