see how today's sky meets your birth chart! pop in your birth details and this page draws your chart, finds every way today's planets are talking to it, and (if you like) asks the stars for a write-up.

your birth details aren't stored anywhere. they're saved only in this browser (so you don't have to type them again), never sent to the server, never put in a web address, and all the chart math happens on your own computer. use "forget my birth details" to wipe them. privacy

your reading
written by Claude, an AI by Anthropic, from the calculated chart above. it only gets the positions: no name, no birthday, no birthplace. up to 3 readings a day.
made right here in your browser. nothing gets uploaded.
how this works
positions: calculated in your browser with astronomy-engine, an open-source astronomy library accurate to a fraction of an arcminute. checked against the swiss ephemeris (what most astrology sites use) to within 20 arcseconds.
conventions: western astrology, tropical zodiac. placidus houses, switching to whole sign houses above 66° latitude, where placidus can't be drawn. traditional rulers, plus the modern co-rulers pluto (scorpio), uranus (aquarius) and neptune (pisces). no birth time? you get a noon chart with no ascendant, midheaven or houses.
aspects: the five major ones, with these orbs (how far from exact still counts):
"building" and "fading": a building (applying) aspect is getting closer to exact; a fading (separating) one has passed. retrograde (R): a planet that looks like it's moving backward from earth.
birth place search: uses the geonames city list (about 170,000 towns), which comes with this site, so what you type never leaves your computer. historical time zones and daylight saving come from your browser's built-in time zone database.
positions are astronomically calculated; interpretations follow astrological tradition and are for reflection and fun.
