Tools 6 found in our last check
search_astrolog_featuresFind matching public Astrolog or Mi Astrologa pages for a user request. Returns canonical free-tool links and short descriptions, never product, purchase or checkout links. Use this before rendering the launch widget.
render_astrolog_featuresRender an interactive Astrolog launch widget for the selected public features. It opens ordinary free-tool pages and contains no product, purchase or checkout actions. Call search_astrolog_features first when you need to inspect or refine the matching results.
compute_natal_chartCompute a real natal (birth) chart from NASA JPL DE440S ephemerides with Skyfield: exact planetary longitudes, sign and degree, house placements (Placidus by default, Whole Sign on request), Ascendant and Midheaven, and the aspects between them. Requires an exact birth date, loc…
resolve_birthplaceTurn a place name into the exact latitude, longitude and IANA timezone needed by compute_natal_chart and compute_transits, using Astrolog's own database of ~100,000 cities. ALWAYS call this instead of supplying coordinates or a timezone from memory: the timezone determines the A…
sky_todayGet what the sky is actually doing right now, computed from NASA JPL DE440S ephemerides with Skyfield: current geocentric longitude, sign and degree for every planet plus Chiron and the Mean Node, the real Moon phase and illumination, which planets are retrograde at this moment,…
compute_transitsCompute real transits to a natal chart over a date window, from NASA JPL DE440S ephemerides with Skyfield. Takes the same birth parameters as compute_natal_chart plus a start and end date, and returns the transiting body, the natal body it aspects, the aspect, the orb and the UT…
