Common questions
Direct answers to the questions we hear most often about charts, transits, and Zenith.
Yes, ideally to the minute. Birth time determines your Ascendant (Rising Sign) and house placements, which can shift dramatically with even a 15-minute difference. If you don't know your exact time, you can still get accurate planet sign placements, but house cusps and the Ascendant will be approximate.
The Porphyry house system is one of the oldest house division methods in Western astrology, attributed to Porphyry of Tyre in the 3rd century CE. It divides each quadrant of the ecliptic, between the Ascendant, IC, Descendant, and Midheaven, into three equal arcs. Unlike Placidus, Porphyry produces valid house cusps at all latitudes, including extreme northern and southern locations.
Daily horoscopes are based only on your sun sign, one of twelve possible chart placements. Astrocurious calculates all ten major planets, the four angles, and the aspects between them, then maps current planetary transits to your specific birth chart. Interpretations are personalized to your placements rather than generic.
Yes. Generating your natal chart, exploring your planet, house, and aspect placements, saving multiple profiles, and viewing your daily transits are all free with no time limit. Zenith Pro ($7/month or $44/year) unlocks weekly and monthly transit views plus AI-generated yearly reports.
Astrocurious uses the Tropical zodiac, the standard system in Western astrology. It is based on the position of the Sun relative to Earth's equinoxes and solstices rather than the fixed stars: 0° Aries begins at the vernal equinox.
Your birth date, time, and location are used to calculate your chart and personalize your transits and reports, including via the third-party services listed in our Privacy Policy (Kerykeion for ephemeris calculations and Anthropic for AI-generated interpretations). We never sell your birth data.
Astrocurious uses the Kerykeion astronomical engine, which draws on Swiss Ephemeris-grade data. Planetary positions are accurate to fractions of a degree for any date and location.
