Happy birthday, universe Oct 23 2006
According to the Ussher-Lightfoot Calendar, today is the 6,009th birthday of the universe. Based on James Ussher's interpretation of the Bible, God created "the heaven and the earth" on October 23, 4004 BC. Happy birthday, everything!
Note: I'm doing Mr. Ussher's precise chronology a disservice by fudging the Julian calendar date that he derived with the Gregorian calendar we now use. For that, I apologize.
