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.
How to find your ascendant with an exact birth time
Your cosmic hello has a time and a place. Your ascendant is the zodiac degree rising on the eastern horizon at birth. Unlike a date-only Sun sign, it depends strongly on both time and location. Choose your birthplace from the city search and use the time from a birth record when available.
Before you begin: check whether your birth record says AM or PM. Then confirm the birth city, rather than the city where you live now. Both are small details with a big effect on the horizon.
Can I find my rising sign without knowing my birth time?
A reliable rising sign cannot be established from your birthday alone. Small time differences can change the result near a boundary. If the time is unknown, explore Sun and Moon placements with limits rather than guessing an ascendant.
