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.
Choose the astrology calculator for your question
One question at a time is a perfectly good way to explore a universe. Start with a birth chart for a broader view. Use the Moon and rising tools for specific placements, or explore Panchang, lunar calendars and planetary transits for a chosen date. Each calculator explains the information it needs and its method.
Not sure where to start? Pick Birth chart for an overview, Moon phase for a sky observation, or Daily Panchang for a local calendar. The calculator selector lets you change your question without changing websites.
