Copying from the LOTR Wiki:

Tolkien said that he thought the distance between the end of the Third Age and the 20th century A.D. was about 6000 years, and that 1958 should have been around the end of the Fifth Age if the Fourth and Fifth Ages were about the same length as the Second and Third Ages. He said, however, in a letter written in 1958 that he believed the Ages had quickened and that it was about the end of the Sixth Age or beginning of the Seventh. (This letter is referred to in the "Fourth Age" article of The Encyclopedia of Arda as mentioned below.) It should also be stated that Arda does not exist in Earth's history, not merely a difference in timeline, but it also as Tolkien stated "in a different state of imaginiation" as in, in the same time but different history.
