The Fifteenth. (But I admit that I have started cheating now.)

[INJ/CdM] I have cheated this morning and discovered that the lowest ordinal for which there is not a non-TV, feature-length film is 31st!

I have a couple in mind for later on, but I looked up 14th. On the other hand Phil's original suggestion included books, and I don't see why we should exclude made-for-TV films as long as they're feature length (say 80 mins minimum). I'm surprised at 31st not being there though as the last day of 7 months and last day of the year.

And when I do look I discover I actually did know a book with 31st in the title - annoying, that.
