'Seventh Year' in the Bible

These are the people whom Nebuchadrezzar took away prisoner: in the seventh year, three thousand and twenty-three Jews:

And in the thirty-seventh year after Jehoiachin, king of Judah, had been taken prisoner, in the twelfth month, on the twenty-fifth day of the month, Evil-merodach, king of Babylon, in the first year after he became king, took Jehoiachin, king of Judah, out of prison.
