acult (Comprehensive Universal Logic Tool) is a Vedic astrology (Jyotish) engine that computes kundli charts from VSOP87 and ELP-2000 planetary theory, corrected for ΔT, in the sidereal zodiac with Lahiri ayanamsa. It produces divisional (varga) charts, Shadbala, Ashtakavarga, KP sub-lords, Vimshottari dasha, gochar (transits), Panchang and Bhrigu Nandi Nadi, in North, South and East Indian chart styles, in English and Hindi.
Every result is either arithmetic you can check against an ephemeris or a classical rule shown with its reasoning. acult tested its own dasha event-timing engine against 866 dated life events, found it performed no better than chance, published the result, and removed date predictions from the product.
