607 B.C. Definitive Why 607 B.C. ( 537 B.C. Calculated ) ( 70 Years Desolation - Beginning and Ending ) Almost all early Bible chronology ties in with secular history at the year 539 B.C., in which year the fall of Babylon to Darius and Cyrus of the Medes and the Persians occurred. In late years several cuneiform tablets have been discovered pertaining to the fall of Babylon which peg both Biblical and secular historic dates. The one tablet known as the "Nabunaid Chronicle" gives the date for the fall of Babylon which specialists have ascertained as being October 12-13, 539 B.C., Julian Calendar, or October 6-7, 539 B.C., according to our present Gregorian Calendar. This tablet also says that Cyrus made his triumphant entry into Babylon 16 days after its fall to his army. Thus his accession year commenced in October, 539 B.C. However, in another cuneiform tablet called "Strassmaier, Cyrus No. 11" Cyrus' first regnal year is mentioned and was determined to have begun March 17-18, 538 B.C., and to have concluded March 4-5, 537 B.C. It was in this first regnal year of cyrus that he issued his decree to permit the Jews to return to Jerusalem to rebuild the temple. ( Ezra 1:1 ) The decree may have been made in late 538 B.C. or before March 4-5, 537 B.C. In either case this would have given sufficient time for the large party of 49,897 Jews to organize their expedition and to make their long four-month journey from Babylon to Jerusalem to get there by September 29-30, 537 B.C., the first of the seventh Jewish month, to build their alter to Jehovah as recorded at Ezra 3:1-3. Inasmuch as September 29-30, 537 B.C., officially ends the seventy years of desolation as recorded at 2 Chronicles 36:20,21, so the beginning of the desolation of the land must have officially begun to be counted after September 21-22, 607 B.C., the first of the seventh Jewish month in 607 B.C., which is the beginning point for the counting of the 2,520 years.
