Heidegger's Bible Handbook: Nehemiah: Chronology
The Chronology of the Book is gathered out of Nehemiah 1:1; 2:1; 13:6. In the twentieth year of Artachshasta, or Artaxerxes Longimanus; in the month Chisleu, Nehemiah mourns in Susa (where the Kings of Persia were wont to winter, as Athenæus, Book XII of Deipnosophistæ, confirms), Nehemiah 1:1, 2. In the month Nisan of the same year, he obtains from Artaxerxes the authority to rebuild Jerusalem; and he, proceeding in the same, begins and perfects the work, Nehemiah 2:1, 2; etc. In the thirty-second year of the same King, he returns to reform Jerusalem, Nehemiah 13:6. There is an interval of twelve years, in which the matters narrated and conducted in this book are completed.
 Athenæus of Naucratis (late first, early second century AD) wrote Deipnosophistæ (or Banquet of the Learned), a dialogue in which the characters discuss a wide range of topics.
