Cellarius Horoscope
Daily horoscopes computed from real planetary positions
Most horoscope sites reuse the same generic text. Cellarius Horoscope is different: an astronomy engine tracks the real, minute-accurate positions of the planets, and every horoscope is computed from that live sky data. Free, no sign-up: horoscopes for all 12 signs, birth chart, rising sign, moon sign and name analysis calculators, a live planetary orrery and moon calendars through 2028. English (US/UK), Dutch, German and French. Design inspired by Cellarius' 1660 star atlas.
Hi everyone! 👋
I built Cellarius Horoscope because every horoscope site I found uses
the same generic text, while the actual sky is different every day.
So I built an astronomy engine that tracks the real positions of the
planets — accurate to the minute — and generates the daily, weekly and
monthly horoscopes from it.
What's inside:
✦ Daily, weekly & monthly horoscopes for all 12 signs
✦ Free birth chart, rising sign, moon sign and name analysis calculators
✦ Live planetary orrery and moon calendars through 2028
✦ Dark & obsolete constellations — the sky's forgotten stories
Everything is free, no sign-up. Available in English (US/UK), Dutch,
German and French. The design is inspired by Andreas Cellarius' 1660
star atlas Harmonia Macrocosmica.
I'd love your feedback on:
1. The astronomy calculations (are they accurate?)
2. The design (does the Cellarius style work?)
3. Whether the horoscopes feel personal rather than generic
Happy to answer questions about the engine or the stack (Next.js on
Vercel). Thanks for checking it out! 🔭
