A Prashna kundali (a 'question chart') is cast for the moment a question is asked, not for anyone's birth (Raman, introduction to the Praśnatantra).Source: Raman, Prasna Tantra, introduction, p. xiii
Choose what your question is about and the city you are in now, then press Cast. You don't need your birth details.
We use some of the Tājika rules of the Praśnatantra and the Hāyanaratna. The Praśnatantra is a Sanskrit text on questions whose core comes from a 9th-century Arabic book by Sahl ibn Bishr (Gansten 2014); Tājika is the Persian and Arabic astrology that was put into Sanskrit.Source: Gansten 2014, pp. 101–109
We don't read questions about health or recovery, death or lifespan, pregnancy or a baby's sex before birth, court cases, or missing people, missing pets and theft. A chart reading could do real harm there, and other help is better:
A chart cast for the moment a question is asked, rather than for a birth (Raman, introduction to his translation of the Praśnatantra). This page reads it with some of the Tājika rules of the Praśnatantra and the Hāyanaratna; 'What does this page not compute?' below lists what it leaves out.Source: Raman, Prasna Tantra, introduction, p. xiii; Hāyanaratna 3.3, tr.

No text we checked gives a way to weigh all these factors together into one answer, and no study has shown that Prashna predicts outcomes. So we show each factor and what a named text says about it, and we don't add them up into a yes, a no or a score.
Because a chart reading could do real harm there, and other help is better. The section 'Questions we don't read' lists who can help.
The second our server receives your Cast, at the centre of the city you pick. We don't ask for your location.
We show the same chart for the same topic for 48 hours on this device, so asking again doesn't give a different chart just because the moment changed.
You don't type a question; you choose a topic. Our servers keep no record of what you cast. This device keeps the moment, the city and the topic for 48 hours, and clears them the next time you open this page after that.
Timing, remedies, and several Tājika rules: radda in full (we check only a planet that is retrograde or in the 6th, 8th or 12th house), maṇaū, tambīra, a third planet carrying the link between the rulers (nakta and yamayā), the grades of kambūla, the planets' dignities and the texts' numeric strengths. It also doesn't use the KP (Krishnamurti) number method or the Kerala Praśna Mārga method, which relies on a ritual.
No study has shown that Prashna predicts outcomes. We found no peer-reviewed test of Prashna; a 2024 pilot study of horary astrologers' timing (eleven events, with a control group of non-astrologers) calls its own result suggestive because the sample is small. Controlled tests of birth-chart astrology found astrologers did no better than chance (Carlson, Nature 1985; Narlikar and others, Current Science 2009). What each factor means here is the tradition's reading, not a prediction.Source: Alexey Borealis, a pilot study of horary astrologers (2024); Carlson, 'A double-blind test of astrology', Nature (1985); Narlikar and others, 'A statistical test of astrology', Current Science (2009)
Hindi and Hinglish versions will come after human editors have reviewed them.
Whole-sign houses counted from the rising sign. The Tājika texts use these for every judgement except a house's own results, which they read from a separate quadrant figure (Hāyanaratna 1.9); we don't compute that figure and apply the house rules to whole-sign houses too. The ayanamsa (where the zodiac starts) is Lahiri, as everywhere on this site.Source: Hāyanaratna 1.9, tr. Gansten 2020
The Praśnatantra (1.7–10) asks the astrologer first to judge whether the question is sincerely put (Gansten 2014, pp. 113–114). A page cannot judge that, so we cast for every question asked.Source: Gansten 2014, pp. 113–114 (Praśnatantra 1.7–10)
