Our Story

AstroGuru is a byproduct of building Kalika, a state-of-the-art Vedic astrology intelligence system. Thirty years of software engineering and twelve years of astrology study, combined with AI, made it possible to apply ancient Vedic teachings and validate them with scientific methods.

We founded this work on one belief. Vedic astrology belongs to humanity. It is for all of us to uncover our karma and the journey it shapes through life.

The project is blessed and guided by Maa Kali, the Goddess of Time, and Maa Saraswati, the Goddess of Wisdom and Knowledge. We named it Kalika to honor Maa Kali, and because kala means the flow of time and the journey of a life. To read a chart is to read karma through kala.

This work led to two patent applications and an innovative rule-based validation engine, the foundation of a unique Vedic astrology intelligence platform. AstroGuru opens that same validation technology to the astrology community. The method we used to build Kalika is now yours to use by hand.

How validation works

The corpus

79,654 birth-data records sourced from AstroDB (Astrodatabank), the largest open corpus of charts with verified birth times and biographical event data.

76,133 fully computed charts (95.6% success rate) using Swiss Ephemeris with Lahiri ayanamsa
104,904 life events: births, marriages, accidents, deaths, career milestones, recognitions
15 divisional varga charts per record: D1, D2, D3, D7, D9, D10, D12, D16, D20, D24, D27, D30, D40, D60, plus karakamsha

The math

Every reported result carries an honest uncertainty estimate.

Precision and recall Precision = TP / (TP + FP) Recall = TP / (TP + FN)

Wilson 95% confidence interval on a proportion p_w = ( p + z²/(2n) ± z·√( p(1−p)/n + z²/(4n²) ) ) / ( 1 + z²/n )
with z = 1.96 for 95% confidence.

Wilson handles small samples and proportions near 0 or 1 correctly, unlike the Gaussian approximation.

Beta-Binomial posterior for small subsets (n < 100) Posterior ~ Beta(α + TP, β + FP)
with uniform Beta(1, 1) prior. Report posterior mean and 95% credible interval.

Bonferroni correction for multiple-hypothesis testing α_adjusted = α / m
where m is the number of hypotheses tested.

Classical systems supported

Parashara (Brihat Parashara Hora Shastra) — primary
Krishnamurti Paddhati (KP) with sublords and significators
Jaimini (with chara karakas, karakamsha)
Yogini dasha (positive and negative signs)
Nadi astrology cross-references
Western Tropical cross-reference (where useful)

Aggregate-first: All statistical results display as aggregate counts and rates by default. Individual chart drilldown requires explicit per-chart confirmation.
Death-event policy: Death-timing analysis is available for research purposes only. AstroGuru never produces consumer-facing death predictions.
Privacy: User-submitted charts are private by default. Hypothesis submissions are private unless explicitly published to the public library.
