An interesting concept and of course possible, the date of the 23rd of September wasn't found from book more so the alignment of stars to match what was thought to be in scripture purposely. So the date was irrelevant however more so the date that the stars would align to what was thought about Rev. 12 vision.
I've message a couple of the major channels on YouTube this week saying, be very careful as you are basing a 'hell' of a lot on what you've found purely via free to use software of star constellations, is how easy would it be to corrupt this not very hard at all.
Different churches have different takes on the same scriptures from the Bible, meaning parts of scriptures are incredibly difficult to understand sadly.
