The true zodiac originally included a 13th zodiac sign called Ophiuchus that was knowingly left out by ancient Babylonians in order to align the number of signs to the number of months in the year. Ophiuchus is between Scorpio and Sagittarius in the astrological zodiac wheel, this means the rest of the zodiac would also have to shift to account for it. This also means that, your zodiac sign might be different than what you've thought it was your whole life. (This is the astrology collapse disorder)
Ophiuchus is represented by the symbol of a snake. Ophiuchus accounts for about 18 days worth of the Sun's residency annually — which would mean that people born between November 29 to December 17 would be assigned to the sign of Ophiuchus instead of being Scorpios or Sagittarians (which are the signs that currently rule the Ophiuchan birth dates). But of course, this wouldn't just affect people born during this period: The whole zodiac shifts in order to make space for Ophiuchus, meaning that many people would find themselves trying to identify with an entirely new sun sign.
In the currently-accepted world of western astrology, there are only 12 zodiac signs. You might think that adding a 13th wouldn't be a big deal (save that for the people, including myself, who go into full-on attack mode before being willing to change their sun sign) — again astrology collapse disorder, astrology is a complex system that uses a lot of math and categorization, First the number 12 divides t
he zodiac wheel into an even number of slices — and it also aligns to the 12 months of the year, the 12 houses of the zodiac, and the four seasons (with spring, summer, fall, and winter each broken down into groups of three zodiac signs). The 12 signs are evenly categorized into four astrological elements (with three signs assigned to each), three astrological modalities (with four signs assigned to each), and two astrological polarities (with six signs assigned to each). You can see how a 13th sign creates a CONFUSING mess as far as the structured base of the zodiac goes.
Ophiuchus is a real constellation, there's no way around that. But the zodiac signs are based on real constellations, there are way more than 12 constellations on our radar — and not all of those have a zodiac sign. Astrology and astronomy both track the movement of planets and other celestial objects, but are two very different things. That said, it's not too surprising to think that Ophiuchus was left out of the astrology sign party back when the Babylonians created the zodiac by dividing the sky into 12 parts ............To be Continued

I wanna know more about why it was left out and the process behind it. Also how it's position effects the signs around it. Plus I loved your use of Astrology collapse disorder.
