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, the ratio being that 1 year in Narnia is equal to approximately 6.7 hours on Earth.

Controversy
It is disputed if there are indeed 7 years between the events of The Silver Chair and The Last Battle and the second "9" in "1949 was meant to be a "3" which had just been misread by Hooper from Lewis' own handwriting.
