I don't know how I've missed this all these years. I'm a huge Tolkien fan, and couldn't get enough of The Hobbit, The Lord of the Rings and The Silmarillion when I became a teenager.
Apparently, others have celebrated September 22 as Hobbit Day, and the corresponding week as Tolkien week, for decades. Bilbo and Frodo's shared birthday, September 22 is the date of The Long Awaited Party.
I hated the cartoon version, so waited anxiously for Peter Jackson's movie version to come out, ready to declare it a sacrilege against the trilogy. Thankfully, it was amazing. Aragorn and Legolas especially, lol. In some ways, it's a shame, because Tolkien's works are best experienced through reading.
