Source overview
The International Astronomical Union defines constellations as areas of sky surrounded by coordinate boundaries. This differs from the equal 30-degree signs used by twelve-sign astrology.
What the source establishes
Why constellations are bounded sky regions rather than equal zodiac signs.
Limitations
The source supports the astronomy or calendar claim described above. It does not validate astrological personality interpretations or predictive claims.
Practical meaning
This distinction allows Zodiac Calendar to use scientific sources for measurable sky facts while clearly labeling astrological symbolism as interpretation.
Editorial note: Astrological meanings on this page describe established traditions and interpretive frameworks. They are not presented as scientifically demonstrated personality facts.
