There's a numerical code throughout The Shining that explains the date at the end of the movie.

Rating: 10/10 (5 July 2007)

If you know where to look there are hundreds of obvious references to special numbers from beginning to end, well-hidden changes in the colors of possessions and surroundings, important shots filmed entirely in mirrors, and many props that visually disappear than re-appear and move around throughout the movie. Stanley Kubrick's Shining brings 'hidden in plain sight' to a brand new level and the movie is a cinematic maze of clues and purposeful visual anomalies and numbers just waiting to be discovered by viewers and leading eventually to the date at the end and something outside of the movie. So be warned, you'll never be able to look at this movie the same way again if you read this. Go to; http://www.moviemistakes.com/phpBB2/viewtopic.php?t=2759 and click on "The Shining"
