Before publishing I found this while trying to see if there was a already a riddle like it out there (closest I could find was the 1000 barrels of wine riddle mentioned at the beginning): https://puzzles.nigelcoldwell.co.uk/

You can also think of this riddle as a very symmetric version of Wordle, where instead of trying to solve for a permutation of letters you're solving for a permutation of years.
