Free solar arc directions calculator: find your current solar arc and the directed-to-natal contacts active now — the slow predictive hits that define a chapter.
Secondary progressions advance your chart a day for every year of life. The solar arc is simply how far the Sun has moved in that time — a little under a degree per year — and the technique applies that same arc to every planet at once. A directed planet's position is just its natal degree plus the arc, which is why solar arc is one of the cleanest predictive methods to read.
Because the whole chart moves at one rate, a directed planet reaches an exact contact with a natal point only once in your life. That makes solar arc hits feel structural — a directed Sun to natal Saturn, or directed Mars to the Ascendant, often lines up with a genuine turning point. They are slow and unmistakable, read with a tight orb of about a degree, which is roughly a one-year window.
It calculates your true solar arc from the progressed Sun using the Swiss Ephemeris, then applies that arc to each natal planet and checks for contacts to your natal planets, Ascendant, and Midheaven within about a degree. The result is the short list of directed contacts active in this chapter — the themes worth working with consciously rather than being caught by.
Solar arc directions move every planet in your chart forward by the same arc — the distance the Sun has progressed since birth, roughly one degree per year of life. When a directed planet reaches a natal point, it marks a slow, defining development.
Transits are the real sky moving over your chart and they repeat often. Solar arc directions move your whole chart forward at one steady rate, so each contact happens once in a lifetime and tends to mark a bigger structural turning point.
Solar arc contacts are read tightly — about one degree, which corresponds to roughly a one-year window on either side of exact. This calculator flags contacts within that orb.
