It's not bad enough that we have a year numbering system based on the unverifiable birthdate of a rabbi/carpenter who may or may not have actually existed, but we also have five of seven days of the weeks named after mythical deities who definitely never existed, five months named after similarly nonexistent deities, two months named for long dead Roman emperors, one month named for a defunct Roman purification ceremony, and four months named for numbers, but those numbers don't reflect where those months fall in the calendar year. Of the nineteen names assigned to our days and months, only Sunday and Monday, named for the sun and moon, make sense. The rest of them need to be tossed out and replaced with more relevant names. Since we have two days named for things in nature (the sun and moon), let's name the other five after similar things like "Waterday". Then, let's rename the months after abstractions like love, courage, kindness, etc.
