The Moon in 'The Hobbit'

J.R.R. Tolkien had retroactively tried to make the lunar phases described in his novel 'The Hobbit' consistent, and he failed. Quite by chance, he had got it almost right, though, despite operating with false premises discussed in this book.Incidentally, the lunar phases of 'The Hobbit' ran synchronous to those of 2017, which had provided the chance to verify them against reality. That is why this 'Extended Edition' includes much of the day-by-day timetable of Bilbo Baggins' adventures and the relevant phases of the Moon that has first been published online. As a further bonus, the chapter on the calendars of Middle-earth has been amended and the arithmetic errors of the shorter edition removed. A previously unpublished chapter on the measuring of hours in Middle-earth has been added.
