Methodology
What the score actually is.
The Astral Edge score is a traditional-astrology-informed timing heuristic, not an empirically validated predictor. We pre-registered 53 astrological hypotheses and tested them at 10,000 permutations on a cohort of ~1,000 documented life events, with a proper discovery/held-out split. Zero hypotheses replicated at FDR-corrected significance across both arms. Earlier versions of this page reported "BY-FDR survivors" and a "held-out lift" number — those claims were artifacts of a broken statistical null and have been retracted. Here's the honest picture.
What the scorer is
The production score is a weighted blend of traditional astrological techniques: partile transit hits (benefic vs challenging), secondary-progression support, planetary-hour alignment, and Hellenistic / Vedic timing flags. Weights are theory-anchored — chosen from the classical literature each technique is drawn from, not fitted to data.
Think of it as an astrological calculator with a structured point system. If you're an astrologer, you can read it as "are today's classical supportive conditions stacking up, or are today's challenging ones?" If you're not, treat it as a reflective timing heuristic — a prompt, not a prediction.
What the scorer is NOT (important)
Not an empirically validated predictor. We pre-registered 53 astrological hypotheses and tested them at 10,000 permutations on a cohort of ~1,000 documented life events, with a proper subject-level discovery / held-out split and a label-shuffle null. Zero hypotheses replicated at BH-FDR q=0.05 across both arms. One hypothesis (a "classical benefic-weekday" pattern) came close, but its most parsimonious reading is a news-cycle artifact — not astrological signal.
Cross-validated classification AUC is 0.505 — chance. The scorer as a "lucky vs unlucky day" binary classifier does not outperform a coin flip on held-out data.
We retracted earlier claims. Earlier versions of this page referenced "BY-FDR survivors," a "15.1% held-out lift," and numbered hypotheses as validated signals. Those claims were artifacts of a statistical-null construction error (subject-shuffle where label-shuffle was correct) plus a discovery / held-out subject leakage. When the analysis was rebuilt correctly, none of those claims survived.

Why ship this at all
Because classical astrology has been scored by hand for two thousand years, long before anyone had a way to validate it against outcome data. The vast majority of astrology apps and astrologers use exactly this kind of theory-anchored scoring, just without telling you it's theory-anchored.
We're telling you. The score is a structured way to explore classical timing on your own chart. It's an interface to a tradition, with full disclosure that the tradition didn't survive our rigorous empirical test. Use it if that's useful to you. Skip it if you want predictive performance, because nobody, including us, has demonstrated that.
