● Business tablets.
What are they? Most business tablets from the Neo-Babylonian period are legal receipts. The tablets were dated to the day, month, and year of the reigning king. For example, one tablet states that a transaction took place on “Nisan, the 27th day, the 11th year of Nebuchadrezzar [also known as Nebuchadnezzar II], king of Babylon.”4

Nebuchadnezzar II destroyed Jerusalem in his 18th regnal year.—Jeremiah 32:1.
If the 37th year of Nebuchadnezzar II was 568 B.C.E., then Jerusalem was destroyed in 587 B.C.E.

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, this method of dating works only if each king followed the other in the same year, without any breaks in between.
They throw this piece of STUPIDITY in here to make you question yourself... "Was there another king in here?" "Could there have been?" Really, the WT just asks "how many months were overlapping?" "could this mean?" .... and even if the kings overlapped by months, so what!? It comes no where CLOSE to the 20 year difference, remember that!
We also have to realize that ALL of the dates WT gets are from...... ta ta da dahhhhh.... the same sources they want you to question! They USE cuneiform tablets, etc... and wow, as long as they can "work it" to go with their ideas... they use it! See?

A PIVOTAL DATE IN HISTORY
The date 539 B.C.E. when Cyrus II conquered Babylon is calculated using the testimony of:
▪ Ancient historical sources and cuneiform tablets: Diodorus of Sicily (c. 80-20 B.C.E.) wrote that Cyrus became king of Persia in “the opening year of the Fifty-fifth Olympiad.” (Historical Library, Book IX, 21) That year was 560 B.C.E. The Greek historian Herodotus (c. 485-425 B.C.E.) stated that Cyrus was killed “after he had reigned twenty-nine years,” which would put his death during his 30th year, in 530 B.C.E. (Histories, Book I, Clio, 214) Cuneiform tablets show that Cyrus ruled Babylon for nine years before his death. Thus, nine years prior to his death in 530 B.C.E. takes us back to 539 B.C.E. as the year Cyrus conquered Babylon.
Confirmation by a cuneiform tablet: A Babylonian astronomical clay tablet (BM 33066) confirms the date of Cyrus’ death in 530 B.C.E. Though this tablet contains some errors regarding the astronomical positions, it contains the descriptions of two lunar eclipses that the tablet says occurred in the seventh year of Cambyses II, the son and successor of Cyrus. These are identified with lunar eclipses visible at Babylon on July 16, 523 B.C.E., and on January 10, 522 B.C.E., thus pointing to the spring of 523 B.C.E. as the beginning of Cambyses’ seventh year. That would make his first regnal year 529 B.C.E. So Cyrus’ last year would have been 530 B.C.E., making 539 B.C.E. his first year of ruling Babylon.

However, the box on page 31 says:
*** w11 10/1 PAGE 31 When Was Ancient Jerusalem Destroyed?—Part One ***The WT will praise and use a source as if it was written by God on one hand: "hey, it supports our ideas!"... and condemns them as soon as it doesn't! And that, my friend is why we all felt crazy!
A QUICK SUMMARY
▪ Secular historians usually say that Jerusalem was destroyed in 587 B.C.E.
▪ Bible chronology strongly indicates that the destruction occurred in 607 B.C.E.
▪ Secular historians mainly base their conclusions on the writings of classical historians and on the canon of Ptolemy.
▪ The writings of classical historians contain significant errors and are not always consistent with the records on clay tablets.
cha ching! cha ching! WT ain't gettin' no more of my bling!
