‘scholar’:
Thus when he refers to a period pertaining to Neb then that must be accounted for if one wishes to construct an authentic chronology of the period.
But you can’t.
There is no need as it lacks chronological detail for the purpose of Bible Chronology but cannot be ignored by advocates of Neo - Neo-Babylonian chronology as it was a historical event. during the reign of Neb.
It seems poor doofus doesn’t understand that the total duration of Nebuchadnezzar’s reign (including any spurious 7 years of insanity) is the same in the JW chronology as it is in the actual chronology (necessitated by the Bible’s identification of Jehoiachin’s release from prison), though the JW chronology moves it 20 years earlier and messes up the order of events at the beginning of his reign. So the only way to ‘account for the seven years’ in any meaningful way is to specify a range of years, otherwise someone (if they believed it was a real period) could just assert that the 7 years of insanity was ‘some time after 587 BCE’.
