Do I need to know my birth time to use Prashna?

No. Prashna is specifically designed for situations where birth details are unavailable. The chart is cast for the moment the question is asked — the question itself is the starting point.

How is this different from asking the AI a question?

Ask-your-chart uses your natal chart and runs interpretations against it. Prashna creates a brand-new chart from the moment of the question and reads the answer from that chart. Useful when the question isn't really about you — e.g. 'Will this deal close?' or 'Is this lost object findable?'

For well-formed questions with a sincere intent and a defined answer scope, yes — Prashna is one of the most time-tested branches of Vedic astrology. For vague or manipulative questions (testing it, asking the same thing repeatedly), reliability collapses. The chart responds to the quality of the asking.

What kinds of questions work well?

Yes/no questions. Timing questions ('when will X happen?'). Outcome questions about a specific undertaking. Questions about lost objects. Questions about a third party's intentions. Questions that won't resolve in the world for years don't work as well — Prashna reads the near horizon.

What is Prashna? Ask a question, cast a chart on that exact moment

The one-sentence version

Prashna is Vedic horary astrology. You ask a question. A chart is cast at that exact moment. The chart answers.

The moment-of-asking principle

In natal astrology, your chart is cast for the moment you were born. In Prashna, the chart is cast for the moment you ask a question.

The classical texts treat the question itself as a kind of birth — the birth of an intention, an undertaking, or a worry. The sky at that moment describes that intention the same way a natal chart describes a person.

So if you're wondering “will this business deal close, and if so when?” — the moment you consciously ask is the moment the Prashna chart is cast.

Why this is powerful

Because it solves three problems natal astrology can't:

No birth time.You can read someone's question about their situation even if they don't know their own birth details.
Not about you.Questions like “will my missing wallet be found?” or “is this candidate trustworthy?” aren't about your life arc — they're about a specific situation. Prashna is built for exactly this.
Near-term precision. Prashna is particularly sharp for short-horizon predictions — weeks to months — where natal dasha-based reading is too coarse.

What a Prashna answer looks like

A Prashna reading typically gives:

A yes/no verdict — based on the chart's overall disposition.
A timing window — when, if yes.
A quality signal — if yes, is it a smooth yes or a hard-won one?
Warnings — factors that could flip the answer.

The classical answer isn't just “yes” — it's “yes, by Thursday, but with an unexpected delay midweek from a financial snag.” The richness of the reading tracks the richness of the chart.

How to ask a good Prashna question

One question at a time. Compound questions confuse the chart.
Sincere, not testing. The classical texts are strict about this: a question asked to test the system usually produces a scrambled chart.
Defined scope.“Will I ever be rich?” is too open. “Will this specific deal close this quarter?” is Prashna-shaped.
Genuinely uncertain.Don't ask about things you already have the answer for.

What the app does

Casts a Prashna chart from the moment you submit a question.
Runs classical Prashna reading rules — ascendant strength, 7th house for the question, 10th for the outcome, the Moon's condition.
Applies specific Prashna yogas (e.g. Gulika position, hora at the time of query).
Returns a yes/no, timing estimate, and the reasoning based on specific classical rules.

Classical source

The standard Prashna references are Prashna Marga (Kerala lineage), Prashna Tantra by Neelakantha, and the Prashna chapters of Brihat Parashara Hora Shastra. Prashna is arguably the most tested and reliable branch of Vedic astrology because the question-and-answer cycle provides immediate feedback.
