This is a response to a question posed, " How do you know Cyrus released the Jews in 537BCE, rather than 538BCE or 536BCE?"
By Cyrus' decree the Jewish exile was ended therefore fulfilling his commission as Jehovah's ‘anointed shepherd' for Israel. (2Ch 36:22, 23; Ezr 1:1-4) The proclamation was made "in the first year of Cyrus the king of Persia," meaning his first year as ruler toward conquered Babylon. The Bible record at Daniel 9:1 refers to "the first year of Darius," and this may have intervened between the fall of Babylon and "the first year of Cyrus" over Babylon. If it did, this would mean that the writer was perhaps viewing Cyrus' first year as having begun late in the year 538 B.C.E. However, if Darius' rule over Babylon were to be viewed as that of a viceroy, so that his reign ran concurrent with that of Cyrus, Babylonian custom would place Cyrus' first regnal year as running from Nisan of 538 to Nisan of 537 B.C.E.
I will give the guy credit, at least he attempted a response. But notice all the if's and uncertainties in the answer. You would think that such a central doctrine that 1914 is to JW's that the 537BCE date should have some certainty to it.
