What if we were to compare Earth's historical time to Middle Earth's movie runtime? If we were to compare these two and put them side by side, at what point in the movie would you be during the KPG extinction (the event that killed off most of the dinosaurs)? Think of this like Carl Sagan's cosmic calendar. Except instead of a calendar, it is all the Lord of the Rings movies, and instead of the history of the whole universe, it is just the history of the Earth.
So to start out, we need to know how long both are in order to create a conversion rate. The Earth has been around for 4.6 billion years (4,600,000,000 years). If we were to put all the movies together and cut out all the end credits, the movies run for 10 hours, 26 minutes, and 59 seconds. In seconds, it runs for 37,619 seconds.
(Note: I am using the theatrical version for Fellowship, but extended versions for Two Towers and Return of the King because it is all I could find)
With these numbers, for every second that passes in the movies, 122,278.6355 years pass in Earth time. For every year that passes on Earth time, 8.178043x10-6 seconds pass in the movies. Another way to write this is 0.000008178043 seconds pass.
As the Earth has finished forming, our movie begins. The screen is black and about to show the New Line Cinema logo. For several hundred million years the Earth is being bombarded by a shower of meteors. In movie time, the meteor bombardment lasts for about 1 hour and 20 minutes.
As the bombardment stops, Elrond is in a private meeting at his home with Gandalf, and says "men? Men are weak." Time continues on Earth until we get to the formation of the oldest sedimentary rocks we have ever found (3.9 billion years old). At this time in the movie, Bilbo is grabbing Frodo's hand as he is saddened that the Ring has tempted him again (1 hour and 35 minutes into Fellowship of the Ring). This is right after Bilbo makes the scary face at Frodo.
Fast forward in Earth time to the first eukaryotic cells, and in the movies we are already at the Battle of Helm's Deep in the Two Towers. The orcs are firing a ballista at the wall (this is shortly after Gimli asks Aragorn to toss him during the battle).
Fast forward even more to the first mammals and dinosaurs on earth, and we are already well over 3 and a half hours of Return of the King! Frodo and Sam are already inside of Mount Doom, and Golem is attacking Frodo as he is invisible and is about to bite his finger off.
By the time of the KPG extinction (when most of the dinosaurs go extinct), the Ring is already destroyed, the hobbits have already gone home, and Frodo is finishing Bilbo's book with the words "Bilbo's story is now over. There would be no more journeys for him."
The first hominids (our earliest ancestors) come in on the scene of Earth time, but Sam is just closing his gate with his family behind him. There is only seconds left in the film. As "The End" enters the screen in movie time, homo sapiens make their first appearance, the earliest know cave art is found, Julius Caesar was killed, China built the Great Wall, World War 2 was fought, and everyone you and I have ever know were born. The screen fades to complete black, and we are now back at current Earth Time.
Here is a graph of all the time stamps and a direct comparison between Earth time and the movie times:
