The Tolkien Professor, Cory Olsen, once again uses the power of Twitter to answer the internet's burning questions about J.R.R. Tolkien, The Lord of the Rings, and all the associated lore.

How much time passes between 'The Fellowship of the Ring' and 'The Return of the King'? Cory answers all these questions and much more.
