The number 13 was hidden and demonized (aka stolen) by the cabal. It is argued there are 13, not 12 Zodiac Signs. Add in the Sign "Ophiuchus" and re-gig the dates (See post) and you might not be the sign you thought you were all this time Folks!
So I assume we could call them "Ophiuchians". Hard word to get used to though- here's the pronunciation https://www.youtube.com/watch?v=OiRePZgZ13c

So this shows Gemini's in this system are those born (Gregorian calendar) 21st June to 20th July!
