just like septem is 7, novem is 9 and decem is 10.
so the parent comment is saying that while at one point it may have been possible to derive the name from the number of the month, that is no longer the case because names and numbers do not match up and therefor the name would not be undevigintiber. thought it might be septendecimber ;-)
I have something similar with ~/Stuff. ~/Stuff contains a folder per month, and ~/CurrentStuff links to the current folder. From there I have a simple shell-function `mkstuff` to create a folder ~/CurrentStuff/$DAY-"$1".
Naturally, it's a huge mess, but it helps if a colleague is like "Hey, didn't we have an issue back in August with the XYZ?". `ls ~/Stuff/2023-{07,08,09}` tends to find things again.
Besides that, I mostly have Projects/ (git projects I change) and Repos/ (git projects I look at) on my work laptop.
so i open my shell, it drops me into ~/t/, which is symlinked to ~/work/YYYY/DD/MM.
my GTK file picker is also setup to automatically give me the last 3 days on the bookmark bar.
Time is not the _best_ heuristic, but it's not bad.
screenshots from scrot all get dumped into ~/screenshots/ by date.
the only real 'folders' i keep around are ~/src/, ~/bin/ and ~/documents/, with the last being like, tax documents.
