Birth time unknown? Explore the possible rising signs.

Perhaps your family remembers the morning, but no one remembers the hour. Enter the date, place and the time range you know, then answer a short questionnaire. The free experimental quiz compares possible Vedic rising signs. You get candidates to investigate, not a recovered birth time.

    The time you are sure of

    For example, if you were told “in the morning”, enter 05:00–12:00. The narrower the range, the fewer signs compete.

    Your answers are kept only in this browser so you can come back. “Start over” deletes them.

    What you get

    A ranked set of possible rising signs within your birth-time range, with a comparison based on your answers. This is a free, experimental way to explore the possibilities. No sign-up or payment is required.

    What the comparison uses

    The engine calculates which signs rise for your date, place and time range. The questionnaire scores self-described traits against traditional lagna descriptions. The displayed percentages are questionnaire scores, not a measured probability that a sign or birth time is correct.

    What to check next

    Compare the candidates with a full birth certificate, hospital record or what relatives remember. Answers about appearance and temperament can fit several signs. Do not use the result to make a high-stakes decision or treat it as verified rectification.

    Questions

    Can I find my rising sign without knowing my birth time?
    Yes, as an estimate. Your date and place narrow the candidates to the signs that rise during the time range you are sure of, and your answers about appearance and temperament weigh them. With a 2–4 hour range, usually 2–3 signs remain.
    What do the percentages mean?
    They express the questionnaire’s ranking of candidates. They are not validated probabilities or a measure of birth-time accuracy.
    Is the quiz free? Do I need to sign up?
    It is free, with no sign-up and no Telegram needed. Your answers stay in your browser only.
    Why can my lagna differ from my Western rising sign?
    JyotiSoft uses the Vedic sidereal zodiac (Lahiri ayanamsa). It is shifted about 24° from the tropical zodiac, so the lagna is often one sign earlier than the Western ascendant.
    Can the quiz recover a birth time?
    No. Start with records and family recollections. Event-based rectification is a separate experimental tool, and its result also needs independent checking.
