Why we built this
Vedic astrology — Jyotish — is not entertainment. It is a deterministic system for understanding the relationship between planetary cycles and human experience, refined over millennia by practitioners across India and Southeast Asia. Its accuracy depends entirely on precision: the right ephemeris, the right house system, the right divisional charts, interpreted through classical rules.
Most modern astrology apps use the tropical zodiac and psychological generalisation. Stellr does not. We use the sidereal zodiac, Swiss Ephemeris calculations, and interpretations grounded in the Brihat Parashara Hora Shastra — the primary classical text of Vedic astrology.
We built Stellr because most people who are drawn to Jyotish cannot access its depth without years of study or expensive consultations. We wanted to close that gap — to make the system's genuine outputs accessible to anyone, in their own language, at any hour.
How Stellr works
- 01
Enter your birth data
Name, date, time, and place of birth. Stellr geocodes the location and applies the correct timezone historically — including DST corrections and historical timezone boundaries.
- 02
Swiss Ephemeris computation
Planetary positions are calculated with sub-arcminute accuracy using the Swiss Ephemeris. The Lahiri Ayanamsha (the standard sidereal correction) is applied. All 9 Grahas, 16 Vargas, and Upagrahas are computed.
- 03
Classical rule application
House lords, planetary dignities (exaltation, debilitation, own sign, Moolatrikona), Yogas, Ashtakavarga bindus, and Dasha lords are derived following BPHS rules — not statistical weights.
- 04
AI-powered narrative
A language model trained on classical synthesis transforms the computed data into prose you can act on — in your language. Citations to specific chart factors are preserved throughout so you can verify every claim against your actual chart.
What precision means here
- Sidereal precision
- Stellr uses the sidereal zodiac — the basis of all classical Jyotish. Planetary positions are computed with the Swiss Ephemeris, the same engine used by professional astrologers and astronomical research institutions worldwide. Tropical co-ordinates are never used.
- Rooted in classical texts
- Chart interpretation follows the Brihat Parashara Hora Shastra (BPHS), the foundational classical text of Vedic astrology, as well as Jaimini Sutras for special lagnas and Brihat Jataka for yoga classification. We do not invent interpretations — we systematise existing tradition.
- Complete divisional system
- Stellr computes all 16 Shodashavargas (divisional charts) — D1 through D60 — using the Parashari system. The Navamsa (D9) and Dashamsha (D10) receive dedicated interpretation for relationships and career respectively.
- Vimshottari Dasha
- The predictive engine calculates your Vimshottari Dasha to the Pratyantar Dasha (4th) level. Dasha lord strength, mutual relationships, and natal house lordship all factor into the narrative. Yogini Dasha is also computed and available for advanced users.
- Sade Sati tracking
- Saturn's 7.5-year transit over the 12th, 1st, and 2nd houses from your natal Moon — Sade Sati — is tracked in real time. Each of the three phases carries a distinct quality, and Stellr surfaces the phase you are in and its expected character.
- Nakshatra depth
- All 27 Nakshatras are interpreted across the Ascendant, Moon, and Sun positions. Nakshatra lords, sub-lords (Nadi), and Pada (quarter) are used in compatibility analysis through the Ashtakoot (8-fold) matching system — the same method used in traditional Kundali Milan.
Vedic astrology vs Western astrology
The most consequential difference is the zodiac. Western astrology uses the tropical zodiac, which is fixed to the seasons (the vernal equinox always marks 0° Aries). Vedic astrology uses the sidereal zodiac, which tracks actual stellar positions. Due to the precession of the equinoxes — a ~26,000-year wobble in Earth's axis — the two zodiacs are currently offset by approximately 23–24 degrees (the Ayanamsha). This means that most people who identify as a particular Sun sign in Western astrology are one sign earlier in Vedic.
Beyond the zodiac, Vedic astrology places greater weight on the Moon sign and Ascendant (Lagna) than the Sun sign, uses an intricate system of planetary periods (Dashas) for prediction, and applies 16 divisional charts for specialised analysis. Stellr uses all of these — the Navamsa for marriage, the Dashamsha for career, the Saptamsha for children, and so on.
