I have just now looked at your crazy nonsense trying to prove 538 BCE for the Return. Your methodology is plain dumb and simply wrong. My analysis proves quite of subject that the Jews returned home by Tishri of 537 in the first year of Cyrus. The second year of Cyrus saw the laying of the Temple foundation in the second month of 536 in harmony with Josephus.
The year 538 is simply impossible as the Jews returned home by the seventh month, Tishri of 537 and not 538 because Tishri in the first year of Cyrus from Nisan 538-Nisan 537 proves that the seventh month Tishri falls not in 538 but 537BCE. Apostates in their desperation to undermine the integrity of 607 need to resort to desperate means which is plainly shown by your clumsy use of calendation.
My tabulation employs six lines of data based upon the accepted fact that the 1st year of Cyrus ran from Nisan of 538 until Nisan 537 BCE therefore such a framework proves conclusively that the seventh month falls not in 538 but in 537 BCE.
