Details of the Return are found at 2 Chronicles 36:22-23 and Ezra 1:1-3:6. Such narrative gives a complete account of the history and chronology for the return to Jerusalem from Babylon.
That is a matter of opinion that 609 BCE began the dominance of the Babylonian World Power for other scholars would prefer 605 BCE.Both dates of 609 and 605 BCE are unsuitable candidates for the beginning of the seventy years because these dates are simply too 'fuzzy' to be of any value historically.
