Umm... No. Astronomy is a science. Astronomy involves the study of what exoplanetary objects are made of, their mass, their life cycle, etc. Astronomy is not the study of what's happening in the sky and how it compares to your interpretation of the Bible.Footnotes are footnotes, they are potential aides. They have never been canonized and I've never seen a reason to use them as definitive.
Astrology: the divination of the supposed influences of the stars and planets on human affairs and terrestrial events by their positions and aspects
This isn't a "divination" of human affairs from their positions and aspects. The celestial objects are time keeping pieces, and are intended to testify of the divine plan through signs and symbols. Astronomy and understanding the divine through it is a true principle. Astrology is the false counterfeit.

Additionally, you are trying to divine the time of terrestrial events by the easily predictable positions of planets. This is exactly the definition of astrology.
