The Hitchhikers Guide to the Galaxy Timeline

This file was based on the Book _The Hitchhikers Guide to the Galaxy_, _The Restaurant at the End of the Universe_, _Life, the Universe, and Everything_, and _So Long, and Thanks for all the Fish_ by Douglas Adams.

I have put some arrows to help the reader follow every character sequence of events, how each one has iteracted with this confusing time-travel Universe

I am using the correct (but seldom used) convention of 1 billion = 1012. See the main page for more references.

This timeline contains spoilers. Those who haven't read the books and wish to do should not read this page.

And remember: Don't Panic

    The precise date of the destruction of the Earth by the Vogon Construction Fleet can be calculated this way: So, I searched for all Ashes in the 80s where the last test was close to September and England either won or lost by a small margin (so that an Alien invasion might reverse the outcome). The only possible candidates were the 1981 and the 1985 Ashes. But the 1985 Ashes ended on a Monday (September 2), while the 1981 Ashes fit nicely into the timeline.
