Create Solar Arc Directions Chart

Solar Arc is a predictive technique that advances every planet, point, angle, and house cusp in your chart by the same ecliptic arc — the distance the Sun has traveled under the 'day-for-a-year' convention. Because the whole chart shifts as a rigid disk, the angular relationships between bodies are preserved — directed-to-directed aspects mirror your natal aspect pattern. What changes is how the directed chart meets your natal positions and angles.

Secondary Progressions advances each planet at its own day-for-a-year rate — the Sun about 1° per year, the Moon about 13°, outer planets barely moving. Solar Arc advances every body by the Sun's arc, so the chart stays geometrically identical to birth but slides forward as a whole. Both are rooted in the day-for-a-year method but answer different timing questions.

The bi-wheel overlays the directed chart on your natal chart — this is where directed hits to your natal positions appear (e.g. directed Saturn conjunct natal MC). The single-wheel shows the directed chart alone, preserving natal aspect geometry on a shifted wheel.

Cross-aspects between every directed body (planets, Ascendant, Midheaven, Chiron, nodes) and every natal body plus the natal angles. Hits to natal Ascendant and Midheaven are classic Solar Arc timing events for identity shifts and career milestones.

Because the Solar Arc chart moves as a rigid disk, all directed bodies travel at the same rate, so the relative motion between any two of them is zero by construction. We report directed aspect orbs without applying/separating flags rather than surface values derived from natal instantaneous speeds — those would misrepresent the technique.
