[Daniel 2:1 In the second year of his
kingship, Neb·u·chad·nezʹzar had a number of dreams, and he* was
so agitated+ that
he could not sleep.]
[Insight
on the Scriptures, Volume 2 p. 480 - In 624 B.C.E., in the first official
year of his kingship, Nebuchadnezzar again led his forces through Hattu; he
captured and sacked the Philistine city of Ashkelon.]
Notice that the Insight volume, p.480 uses the expression' the first official year of his kingship' so this specific expression refers to his initial reign as King beginning Aug/Sept 624 BCE
Further, Dan 2:1 cannot have referred to his regnal years beginning in either 624 or the accepted date of 605/604 BCE as Neb had not yet then brought the Jewish captives including Daniel who interpreted the dream recorded in Dan. ch.2 to Babylon later on with the first deportation in 617 BCE or the accepted date of 587 BCE some 5 years later.
