Fools and apostrophes

Wondering where the apostrophe goes in the name of a certain April day marked by fools? It looks like this:

April Fool’s day

This is how Merriam-Webster has it and is the placement most agreed upon. To me, though, it seems more fitting to have the apostrophe at the end to make it Fools’ (plural). I mean, certainly there is more than one fool who will be at the wrong end of mean and nasty pranks today. Alas, I am not yet an all-powerful guru, where I can change apostrophe placement and have the world listen. So for now, that’s how you spell it.
