Narnian timeline

This timeline was provided by C.S. Lewis, to map out the events of his series. Narnian time is not in sync with the time on Earth. For instance, when Lucy Pevensie spends a few hours in Narnia she returns to find that only seconds have passed.

Controversy
While the authenticity of some posthumous works attributed to C.S. Lewis edited by Walter Hooper have been challenged (Lindskoog 1988), the timeline is generally accepted by Lewis scholars such as Paul Ford and Martha Sammons, despite a number of seeming discrepancies between the timeline and the text of the books, including the following:
 * The timeline says Digory Kirke was born in 1888 (his similarity in age to Polly in The Magician's Nephew, who the timelines says was born in 1889, backs this up) and confirms him as the Professor of The Lion, the Witch and the Wardrobe. This would only put him in his early fifties in 1940 (when the timeline says "The Pevensies, staying with Digory (now Professor) Kirke, reach Narnia through the Magic Wardrobe") which conflicts with the description of Professor Kirke in The Lion, the Witch and the Wardrobe as "a very old man with white shaggy hair which grew over most of his face as well as on his head".
 * While 1900 is given by the timeline as the year "Polly and Digory [were] carried into Narnia by magic Rings", The Magician's Nephew begins by saying "In those days Mr Sherlock Holmes was still living in Baker Street and the Bastables were looking for treasure in the Lewisham Road." The Bastables were searching for treasure while living at 150 Lewisham Road in E. Nesbit's The Story of the Treasure Seekers; the book is set in 1899, the year before its sequel, The Wouldbegoods (see chapter ten, where a letter dated 1900 is recieved). Both dates tally with Sherlock Holmes, who (according to the 60 canonical stories by Sir Arthur Conan Doyle) was resident in 221B Baker Street from 1881/1882 ( A Study in Scarlet ) until his retirement in 1903/1904, with the exception of a hiatus between 1891 (The Final Problem) and 1894 (The Adventure of the Empty House).
 * Paul Ford points out in his Companion to Narnia that the text of The Lion, the Witch and the Wardrobe states Lucy and Edmund to be one year apart in age, though the timeline gives their years of birth as 1930 and 1932 respectively, putting their relative ages at something more than a year.
 * Queen Swanwhite was said by Jewel the Unicorn to have ruled Narnia before Jadis in The Last Battle but the timeline says she ruled around the year 1502, more than 600 years after Jadis returned to Narnia. This has led some fans to explain the inconsistency with speculation that there were two queen Swanwhites, one before Jadis and mentioned by Jewel, the other in 1502, named after the first and referred to by the timeline.
 * It is disputed if there are indeed seven years between the events of The Silver Chair and The Last Battle or if the second "9" in "1949 was meant to be a "3" which had just been misread by Hooper from Lewis' own handwriting. However, Eustace states in The Last Battle that only he and Jill are still in school. If that was 1943, Peter would have been sixteen, Edmund would have been almost thirteen, and Lucy would have been eleven, and so still at school (compulsory education until the age of fourteen had been enforced in England since the early 1920s).
 * Devin Brown, author of Inside Narnia: A Guide to Exploring The Lion, The Witch, and the Wardrobe uses the timeline as a way to reconcile some of the statements concerning the timing of Aslan's appearances in Narnia with other character's recollection of those appearances.
