Also, forgot to add.... in those same articles Nov/2011 pg 24 the footnote right above the picture of clay tablets reads: "Business tablets exist for all the years traditionally attributed to the Neo-Babylonian kings. When the years that these kings ruled are totaled and a calculation is made back from the last Neo-Babylonian king, Nabonidus, the date reached for the destruction of Jerusalem is 587 B.C.E. HOWEVER [emphasis mine], this method of dating works ONLY [Emphasis mine again] if each king followed the other in the same year without any breaks in between.
They basically admit that the business records only go to 587 B.C.E but we still won't change it.
