I started re-reading The Hobbit recently, not having read Tolkien since before Peter Jackson's Lord of the Rings came out. Fairly early on in the book Gandalf mentions something that happened "On the twenty-first of April, a hundred years ago last Thursday," and as I read that phrase I thought, "Hang on, wasn't last Thursday actually the twenty-first of April?"
So I checked, and it was. Then I realized that Bilbo's unexpected party happened on a Wednesday, which meant the book began on a Tuesday, which happened to be the same day of the week (and thus the same day of the year) I started reading it.
Now, I'm not suggesting this means anything in particular, but still, when surprised by an amusing little coincidence of this sort, one tends to feel that one is doing just the right thing, at just the right time.
