I almost forgot — in 1658, Archbishop Ussher determined that the world was created precisely at 9am, 23 October, 4004 BC, making today the official creation day, and the earth 6012 years old.
Stop laughing, people. There are some who still seriously believe that: I just got spam from Whirled Nut Daily pushing this very silly book, The Annals of the World, buy James Ussher. They call it a masterpiece. I call it a quaint old oddity.
