Not necessary (rgd the edit). Comparative linguistics (however questionable) is a thing. For example, the page for October - https://en.wiktionary.org/wiki/October - does not mention any connection to indo-germanic languages where "october, november and december" have roots that map to the sanskrit "ashta, nava, dasha" (eight, nine, ten) which correspond to the eighth, ninth and tenth months in the roman calendar.

It was coined in 1924. It was made up. Invented. Which part of that was unclear?

For some reason that didn't hit me at all. Perhaps I was already in a mode to draw a link. Apologies.

No problem, we've all done that.
