This isn't fortune-telling.
It's astronomy + classical scholarship.
Vedic astrology — Jyotisha — is a 2000-year observational discipline. It started as the timekeeping system the Vedic ritual calendar required, evolved into a mathematical theory of planetary positions that pre-dates Copernicus by centuries, and reached its classical form in texts like Brihat Parashara Hora Shastra (c. 600 CE) and Phaladeepika (c. 1100 CE).
That tradition has been treated as superstition by people who haven't read it, and as random fortune-telling by people who profit from selling predictions. AstroRight is built to show you the difference. Every reading the app produces is grounded in two things: a precise astronomical computation and a citation from the literature.
The reading
How a single reading is produced.
Every reading inside AstroRight follows the same six-step path. The chain is deterministic and traceable — you can always tap "How is this read?" and see exactly where the answer came from.
Your birth, captured precisely
You enter your birth date, time, and place. AstroRight handles the timezone — including historical edge cases like pre-1947 India, daylight saving shifts in other regions, and the partition-era boundary — so an old birth date in Lahore and a recent birth date in Mumbai are both read with the right local time.
Real planetary positions
For your exact birth moment and place, AstroRight computes where every graha (planet) actually was — accurate to within hundredths of a degree of what professional Vedic astrology software would show.
The Vedic (sidereal) frame
The positions are projected into the sidereal zodiac — the star-anchored frame the Vedic tradition uses — using the Lahiri ayanamsha. You can switch to Raman or KP in advanced settings; the active one is shown on every chart screen.
Chart synthesis
Your Lagna (ascendant) is derived from the eastern horizon at your birth place. Houses are assigned the way the classical texts describe. Each graha lands in its sign, gets its dignity classification, and is mapped to the right bhava (house) from your Lagna.
Classical rule reading
Every yoga, dosha, dasha hierarchy, transit reading, and Ashtakavarga score comes from a hand-authored library of rules — each rule cited to its source chapter in the canonical book. There is no AI guessing what your chart "probably means." The reading is the rule.
Cited back to you
You see the reading in your language, and tap "How is this read?" on any line to see the rule that fired, the chapter it came from, and the astronomical positions that triggered it. Nothing is hidden. You can always trace a reading back to where it came from.
The astronomical engine
Real astronomy. Same engine the professionals use.
Every planetary position in AstroRight comes from the standard astronomical engine that powers professional Vedic astrology — the same one behind the desktop tools serious practitioners have used for decades. The underlying calculations come from the same model that astronomers use to track real planetary motion.
We do not estimate. We do not interpolate. We do not pull positions from a wire-service feed. Charts cast in AstroRight agree with established Vedic software within ±0.02° on planetary longitude and ±0.05° on the Lagna.
When you cast a chart in AstroRight, the planet positions are physically where the planets are. That is what astronomy means.
Verified
We test every release against a library of reference charts to catch any drift. Before public launch, the same library is being independently checked against the leading desktop Vedic astrology tools — so what AstroRight tells you about a chart matches what a serious practitioner would compute.
Sidereal astronomy
Lahiri ayanamsha. Whole Sign houses.
Vedic astrology uses the sidereal zodiac (anchored to the fixed stars), not the tropical zodiac (anchored to the seasons) used in Western astrology. The two have drifted apart by roughly 24 degrees due to the precession of Earth's axis — a real astronomical phenomenon.
The ayanamsha is the offset between the two systems. AstroRight defaults to Lahiri, the standard adopted by the Government of India in the 1950s and the convention every serious Vedic practitioner uses. Raman and Krishnamurti (KP) are available in advanced settings — but they are never silently swapped, and the active ayanamsha is shown on every chart screen.
For house systems, AstroRight uses Whole Sign houses by default — the convention every classical text from Brihat Parashara Hora Shastra onward describes. The sign containing your Lagna is the entire 1st house, the next sign is the entire 2nd, and so on. Sripathi / Bhava Chalit is available as a power-user toggle for those who want the unequal house-cusp view alongside.
These are not arbitrary defaults — they are the conventions that make AstroRight's chart match what a serious user would see in any other reputable Vedic astrology software. If they didn't, the app would be wrong.
The literature
Cited from a 65-chapter classical textbook.
Every interpretation in AstroRight cites the chapter it comes from in Jyotisha — A Complete Study of Vedic Astrology by Mukul Bisen, a 65-chapter modern treatment of the classical literature. The book itself synthesises:
- Brihat Parashara Hora Shastra — The foundational text, attributed to Maharishi Parashara, c. 200 BCE–600 CE. The source for the Vimshottari Dasha system, the foundational dignity tables, and the bulk of the yoga catalog.
- Brihat Jataka — Varahamihira, 6th century. The most-cited classical authority on natal interpretation and the rashi-graha relationships.
- Phaladeepika — Mantreswara, c. 1100 CE. The text that systematised most of the yoga and dosha rules AstroRight encodes.
- Saravali, Jataka Parijata, Hora Sara — Secondary classical references for cross-validation of yoga rules and dosha cancellations.
- Surya Siddhanta — The astronomical text that established the sidereal-zodiac framework AstroRight uses.
- Modern computational refinement — Modern astronomical libraries bring contemporary numerical accuracy to what the classical tradition computed by hand for centuries.
There are no LLM-discovered yogas in AstroRight. There are no AI-invented doshas. Every rule the engine fires has a chapter number behind it. Tap "How is this read?" on any reading and you get the citation, the rule, and the astronomical input that produced the result.
The honest answer
Is Jyotisha a science?
It depends on what part of it you mean.
The astronomical part — yes, unambiguously.
Computing where Saturn was at 4:23 AM on 14 March 1947 in Bombay is a physics calculation. Vedic astronomers were doing it accurately a thousand years before Newton wrote the Principia. They built mechanical observatories — Jantar Mantar in Jaipur and Delhi is still standing — and refined their planetary tables across centuries. The Surya Siddhanta gives values for the length of the sidereal year that are within minutes of the modern figure.
AstroRight's astronomical layer is descended from this lineage, modernised through Swiss Ephemeris. There is no controversy about its accuracy.
The interpretive part — that is a tradition, not a falsifiable science.
Whether a Jupiter-Moon conjunction in the 5th house actually correlates with the life outcomes the tradition associates with it is not something a randomised controlled trial can settle. The sample sizes don't exist. The variables aren't isolable. We are not going to claim otherwise.
What we will claim is that the interpretive system is internally coherent, refined across two thousand years of careful observation by serious people, and worth treating as a reflective lens — the same way you might read poetry or philosophy. AstroRight presents it that way: as a classical pattern, with citation, for your reflection. Not as a prediction.
What we refuse to do.
We won't tell you what will happen. We won't sell you remedies you don't need. We won't declare your match impossible. We won't frame your dosha as an affliction. We won't flatter you with a prediction. We won't terrify you with one either.
That is what separates AstroRight from the broader astrology marketplace. The hoax is not the tradition — it is what bad-faith practitioners have done with the tradition.
Sanskrit terms, kept
Glossary.
AstroRight preserves Sanskrit terminology rather than collapsing everything into English approximations. Serious users speak the tradition in its own vocabulary; we follow that lead. Each term shows up with a parenthetical English on first use per screen.
- Lagna लग्न
- The ascendant — the rashi rising on the eastern horizon at your moment of birth. The foundation of the entire chart.
- Rashi राशि
- A zodiac sign. Twelve total. The sign your Sun, Moon, or Lagna sits in carries classical associations.
- Graha ग्रह
- A planet. Literally "that which seizes." Nine grahas in Jyotisha — seven visible bodies plus the lunar nodes Rahu and Ketu.
- Bhava भाव
- A house — one of twelve life-domain compartments measured from the Lagna. The 7th is partnership, the 10th is career, etc.
- Nakshatra नक्षत्र
- A lunar mansion. 27 total, dividing the ecliptic into 27 equal segments. The Moon's nakshatra at birth keys the entire dasha system.
- Dasha दशा
- A planetary period. The Vimshottari system divides 120 years across the nine grahas in a fixed sequence determined by your natal Moon's nakshatra.
- Gochara गोचर
- Transit. Where the grahas are right now, evaluated against your natal positions.
- Yoga योग
- A combination — a classical pattern of placements that the tradition reads as significant. Examples: Hamsa Yoga (Jupiter exalted in a kendra), Gajakesari (Jupiter and Moon in mutual kendras).
- Dosha दोष
- A consideration — sometimes loosely translated as "blemish," but in AstroRight always presented as a classical observation, never as an affliction or curse.
- Karaka कारक
- A significator. The Sun is the karaka for the soul and the father; the Moon for the mother and the mind; Jupiter for children, knowledge, and dharma.
- Ayanamsha अयनांश
- The precessional offset between the sidereal zodiac (Vedic) and the tropical zodiac (Western). Currently around 24°.
- Kundali कुण्डली
- The popular term for a birth chart in modern Indian usage.
