Different zodiac settings
Popular ayanamsas differ by up to 1°27′. That moves planets across sign edges and can shift your dasha dates by two years.

AstroBench live run, 9 October 2026. What was tested
The problem
Same kundli, different answers. Here is why.
Most disagreement starts before anyone interprets anything. Two readings usually differ because the chart was calculated differently, or because a different definition was used, and both can be fixed.
Guessed birth times
At Delhi, Pisces rises in just 85 minutes. A rounded time can change your lagna, and the navamsa changes every 13 minutes or so.
Different definitions
By one common rule 42% of people are Manglik. By another, 88%. Same chart, different label.
Untested software, and incentives
A calculation bug is inherited by every reading built on it. And a frightening reading sells remedies.
The answer
One standard method, the way the classical texts describe it
For every question, Vani works through the steps an experienced astrologer follows, in the same order, and every finding rests on calculated facts. Change the astrologer, and the method stays the same.
- Houses of the matter and the planets in them
- Their lords: where they sit, their dignity and condition
- Significators: natural karakas and Jaimini’s chara karakas
- The divisional chart for the matter: D9 for marriage, D10 for career
- Yogas and doshas that bear on the question
- The running dasha: mahadasha and antardasha lords
- Transits of Jupiter and Saturn, from the lagna and the Moon
- Strength: ashtakavarga and shadbala
- A weighed lean, never a certainty
The proof
Checked the way a senior astrologer checks a junior
We built AstroBench to test the app the way an experienced astrologer checks a junior’s work: hundreds of consultations, from one-line questions to long conversations, on charts chosen to be difficult. Every calculated value is compared with an independent reference, and every reading is held to what the classical texts say a careful astrologer must weigh.

Why astrologers disagree about the same kundli
Same birth details, different answers. Nine technical reasons kundli readings differ, from ayanamsa to yoga definitions, and how one standard method fixes them.
Manglik dosha: what it is, how it is checked and how common it really is
Which houses make a chart Manglik, how common it is under each rule, what cancels it, and calm, factual answers about marriage and the age of 28.
Vimshottari dasha: the mahadasha order, every antardasha, and how the dates are worked out
The nine mahadashas in order with their years, all 81 antardasha lengths, how the dasha balance at birth is calculated, and why apps disagree on dates.
The 27 nakshatras: list with lords, rashis, all 108 padas, gana, yoni and nadi
All 27 nakshatras with Hindi names, spans, lords, deities and symbols, the 108 padas with their navamsa, gana, yoni and nadi, and how to find your own.
Yogas in your kundli: what they mean and how common each one really is
Raj yoga, Gaja Kesari, Budhaditya, Pancha Mahapurusha, Kemadruma and Kala Sarpa: what each means and how often it appears in 200,000 Indian births.
Vedic vs Western astrology: why your sign is different, and which one is yours
Why your Sun, Moon and rising signs move back one sign in Vedic astrology: sidereal vs tropical, the Lahiri ayanamsa, 2026 sign dates and lagna vs rashi.
Questions
Frequently asked
What is JyotishiVani?
JyotishiVani is a Vedic astrology app for iPhone and Android. It calculates your kundli, divisional charts, dashas, transits, Sade Sati, yogas, doshas and daily panchang, matches charts for marriage, and lets you ask Vani, an AI astrologer, about any of it in English or eight Indian languages.
How is it different from other astrology apps?
It reads every chart by one documented method instead of the opinion of whoever answers. The conventions are fixed and published (Lahiri ayanamsa, mean nodes, whole-sign houses), every calculation is tested against an independent reference, and nothing is stated that your birth time cannot support. There are no paid per-minute consultations, and nothing to buy: no remedies, gemstones or pujas.
Is Vani a real astrologer?
Vani is an AI, and says so if you ask. It does not invent anything about your chart: every planet, house and period it mentions is calculated with Swiss Ephemeris precision and checked before you see it.
How accurate is JyotishiVani?
In our latest benchmark run (9 October 2026), 99.7% of 15,035 calculated values agreed with an independent reference calculation, and all 967 chart statements in Vani's answers were correct. The accuracy page explains what was tested and what we are still improving.
Do I need my exact birth time?
No, but it changes what can be said. A time good to an hour or two usually settles your Moon sign and nakshatra, and with them your dashas and Sade Sati; the date alone settles the Moon sign on only about half of all days. The lagna needs a time good to about 15 minutes, and divisional charts need more. The app tells you which insights your birth time unlocks, and never presents an uncertain value as fact.
Which languages does Vani speak?
Vani answers in English, Hindi, Tamil, Telugu, Kannada, Malayalam, Marathi, Bengali and Gujarati. Tables and calculation details stay in English.
Is my birth data safe?
Birth details, names, messages and answers are encrypted in the database, and each account can only ever read its own rows. Location is approximate, rounded to about a kilometre. You can delete a saved person, a conversation or your whole account at any time.
