WT chronology has established the reigns for the Neo-Bablonian dynasty beginning with Nebuchadnezzar: Nebuchadnezzer reigned 43 years fro Nisan 624-582 Evil Merodach reigns of 2 and 18 years proposed,- 581 -? Neriglissar reigns of 2, 4, 18 years proposed ? labashi-Marduk reign of 9 months - ? Nabonidus reign of 17 years - 566- 539
The book "Babylon the great has fallen" page 184 fills in the proposed years of reign that you have in question.
"begins rule in 580 B.C." (Evil-marodach)
Evil-merodach, two years 578 BC
Neriglassar, four years 574 BC
Labashi-Marduk, nine months 574 BC
Nabonidus "a glorious rule till 539 B.C." ( or 34 years rule)
The only way the WT list above works is if Nebuchadrezzars' rule begins in 605 not 624.
Which would then give Nabonidus the 17 years you gave him.
Its interesting that you use the word "proposed" and a ? mark, this would indicate that your really not sure, and you have to assume the missing years to fit doctrinal implications (1914)
Will you not accept what the FDS has put out in written literature such as the book "Babylon the Great" to fill in the questionable years of rule?
To the average person without any background in neo-Babylonian studies will gladly accept what the FDS has put forth, subsquently 1914 making perfect sense.
So the WT has not "established" years rule.
Its still your turn.
