Authority Astrology: Birth Chart Calculator
Claude connectorCommunityYour birth chart, relationships and planetary cycles, explored in Claude with Swiss Ephemeris calculations.
Turn your birth details into a richer conversation about your chart. Authority Astrology calculates precise Swiss Ephemeris data, and Claude helps you explore what it means in clear, everyday language.
START WITH YOUR BIRTH CHART Explore planetary placements, zodiac signs, houses and aspects. Resolve your birthplace and check local birth times. Exact, approximate and unknown times stay distinct, so you can see which details are supported.
GO BEYOND THE NATAL CHART Compare two people’s charts with synastry or explore a composite chart. Follow current or future transits, secondary progressions, and solar, lunar or Saturn returns. Explore relocated charts and astrocartography, calculate horary and electional charts, or look up eclipses, sky events and celestial positions.
MAKE IT PERSONAL Calculate from details you supply without connecting an account. Connect Authority Astrology when you want to choose a saved birth profile, retrieve a saved raw chart or save a newly calculated chart. You choose what to use and save.
TRY ASKING “Calculate my birth chart and explain the Sun, Moon, rising sign and major aspects.” “Compare our charts and explain the cross-chart aspects.” “What transits affect my natal chart this month?”
Calculations come from Swiss Ephemeris; interpretations come from Claude. Astrology is for reflection and entertainment.
