About
Observer of the hour.
The Greek hÅroskopos was the person who watched the eastern horizon and noted what rose at the hour of a birth. The word kept the watching; this site gives it back.
Most horoscope sites ask you to trust them. We would rather you check us. Every daily reading on horoscope.observer is written from the computed positions of the Sun, Moon and planets on that date, and those positions are printed next to the text, with the exact times of the aspects, so you can see what the words are about. The sky itself, from the Moon's phases to the retrogrades and the eclipses up to 2030, is published as open data that anyone may reuse.
The astronomy is done with the Swiss Ephemeris, the engine behind professional astrology software, and verified against an independent library and against published eclipse and equinox times. The writing is done by a language model under strict rules, and every sentence is checked back against the data before it goes online. We say so openly on the method page, because a horoscope that hides how it was made is asking for a kind of trust we do not want.
What we think about astrology: it is an old and rich language for talking about time, mood and character, not a science and not a prediction machine. We present its interpretations as what the tradition says, we keep the astronomy exact, and we never mix the two registers in one claim. If that sounds dry, read a few of the daily pages; the sky is more interesting when you can see it.
Who makes it
Horoscope Observer is made by a small independent studio in the Netherlands that also publishes jaarhoroscoop.com, a Dutch yearly horoscope with the same computed-and-checked approach, and humanoid.observer, a database of humanoid robots. The company details are on the terms page. Corrections, questions and ideas: hello@horoscope.observer.
What costs money
The horoscopes, the sky pages, the chart tool and the data are free and will stay free. The one paid product is the Birth Chart Report: your full chart read in about forty pages, written from your exact numbers and checked against them. That is what keeps the observatory running without advertising or tracking.
