Using the genealogies in the Bible, Joseph Justus Scaliger worked out that Creation took place on 23 April 3947 BC, Kepler chose 3992 BC, while Archbishop James Ussher went still further, in his Annals of the Old and New Testament (1650–1653), in which he calculated that the week of Creation began on Sunday, 23 October 4004 BC, and that Adam was created on Friday, 28 October 4004 BC. Finally, John Lightfoot (1602–1675), a rabbinical scholar, added to Ussher’s calculations, working out that Adam was born on Friday, 28 October 4004 BC, at nine o’clock in the morning.
