Calculator questions
Do I need my exact birth time?
For a rising sign and house placements, yes. The ascendant moves quickly and depends on location. An unknown-time chart uses noon only as a labeled reference and omits the ascendant and houses. Your Moon sign may also change during the day.
Why are Western and Vedic signs different?
Western tropical astrology begins at the March equinox. Sidereal astrology applies an ayanamsa offset. Astrojelly’s sidereal option uses a documented approximation; it is not a certified Lahiri or professional Kundli calculation.
Are these astrology predictions scientifically proven?
No. Astronomical positions can be calculated and tested. Astrological interpretations are symbolic traditions and are not scientifically established predictions of personality or future events.
How is calculation accuracy handled?
The tools use Astronomy Engine for astronomical positions. We show the zodiac, house system, timezone, and limitations. Birth-time uncertainty, coordinate errors, and sidereal conventions can affect results. We do not claim an untested 99.9% accuracy rate.
Do you save my birth details?
Calculations run in your browser. Broader place searches send only the country and place query to Astrojelly; birth dates, times and results stay in your browser. You can download results to your own device. Standard hosting access logs may still record page visits.
Generate your natal chart, then explore one placement at a time
Our free birth chart generator turns your birth date, local birth time and birthplace into a natal chart wheel and a detailed placement table. Birth chart calculator and natal chart generator describe the same tool here: a calculated snapshot of your birth sky. Start with your Sun, Moon and rising signs, then explore planets, whole-sign houses and major aspects. No sign-up or payment is required.
Your free birth chart with interpretation includes introductory symbolic explanations, not a personalized professional reading. Choose the chart style you enjoy, explore a planet, and save the illustrated report to your device. Your chart details stay in your browser.
Can I calculate my birth chart without a birth time?
You can explore date-based placements with uncertainty, but an accurate ascendant and house layout require a reliable birth time. The Moon may also change signs during your birth day; do not treat an assumed noon time as a verified chart.
