Your chart, and the three placements people ask about first.

What the sky is doing, with exact times in your zone.
Learning
The language itself, one placement at a time.
How we work
Astrology is a symbolic language, not a science. We're exact about the astronomy and honest about the interpretation.
We compute first
Positions come from our own engine, built on the open-source astronomy-engine and checked against NASA JPL data, the U.S. Naval Observatory and NASA's eclipse canon.
We name the knobs
Houses depend on the house system. Every chart says which one it used, and switching shows you exactly what moves.
We say who wrote what
Readings are drafted with software assistance. Then they are either edited by our writers or checked by an automated reviewer against our voice guidelines, and each block says which.
Start reading
Guides edited in full by Moon and Rising editors, and our own research.
How exact does your birth time need to be?
We moved 5,000 sample births by 5 to 60 minutes and counted what changed: the rising sign, the houses, the Moon and the Sun. Here is how much a clock error matters.
