If you think that people who tell you that you've been lied to about most things are conspiracy Theorists, consider this:
February is the last month of the year.
Why...
September is seven
October is eight
November is nine
December is ten
So when someone tells you that you are ignorant because you don't know anything about anything you can tell them that you sure as hell know that the calendar has been appropriated by people who also don't know anything.
February (n.) month following January, late 14c., ultimately from Latin februarius mensis "month of purification," from februare "to purify," from februa "purifications, expiatory rites" (plural of februum "means of purification, expiatory offerings"), which is of uncertain origin, said to be a Sabine word. De Vaan says from Proto-Italic *f(w)esro-, from a PIE word meaning "the smoking" or "the burning" (thus possibly connected with fume (n.)). The sense then could be either purification by smoke or a burnt offering.
The last month of the ancient (pre-450 B.C.E.) Roman calendar, so named in reference to the Roman feast of purification, held on the ides of the month. The Old English name for it was solmonað, which is said to mean "mud month." English first borrowed the Roman name from Old French Feverier, which yielded Middle English Feverer, Feoverel, etc. (c. 1200) before the 14c. respelling to conform to Latin. -- https://www.etymonline.com/word/February
