Deletion of International Speak Like A German Day

Comment: Non-notable.  No external verifiability; all "references" provided are self-referential, and even searching for the broader "speak like a German" yields nothing relevant.  Also calling  and  on statement and first person pronoun use: "This is an established thing. WikiPedia can't delete it, because I delcare it established. - Kez".  Not even ''close'' to being Pirate Day, of which even I've heard

Comment: An item generally belongs on Wikipedia ''after'' its notability is established, as Wikipedia is not a cart-before-the-horse means for establishing this notability, nor is it for "advertising" to that end.  I doubt anyone is criticizing it for never having heard of it; not trying to |bite, but I feel they are simply stating that it does not gel with |why wikipedia exists.  As for Pirate Day, that page was first created, per its revision history, in 2003, certainly well after its inception and popularity grew per the article's references; thus the comparison here is fallacious
