This is an experiment in assigning two-letter codes to episodes of My Little Pony: Friendship is Magic as well as other media in the franchise.
“Alt” codes are sometimes assigned based on preliminary or unofficial titles.
Codes are generally taken from the first letters of words in the title, and subsequent letters if needed.
Two-part episodes always have the codes “XA” and “XB”, where “X” is a prefix determined similarly to what is described above.
Codes are always assigned in order of airing, even when I sometimes haven’t kept up with new episodes.
The source code for this site, including the codes in JSON format, are available on GitHub.
