'Year of' in the Bible

They will be like a tree planted near a stream whose roots spread out toward the water. It has nothing to fear when the heat comes. Its leaves are always green. It has no need to be concerned in a year of drought. It does not stop bearing fruit.

The following events occurred in that same year, early in the reign of King Zedekiah of Judah. To be more precise, it was the fifth month of the fourth year of his reign. The prophet Hananiah son of Azzur, who was from Gibeon, spoke to Jeremiah in the Lord's temple in the presence of the priests and all the people.

In the tenth year that Zedekiah was ruling over Judah the Lord spoke to Jeremiah. That was the same as the eighteenth year of Nebuchadnezzar.

This is the order Jeremiah the prophet gave to Seraiah son of Neriah, son of Mahseiah, when he went to King Zedekiah of Judah in Babylon during the fourth year of his reign. (Seraiah was a quartermaster.)

On the tenth day of the fifth month, in the nineteenth year of King Nebuchadnezzar of Babylon, Nebuzaradan, the captain of the royal guard who served the king of Babylon, arrived in Jerusalem.

In the thirty-seventh year of the exile of King Jehoiachin of Judah, on the twenty-fifth day of the twelfth month, Evil-Merodach, in the first year of his reign, pardoned King Jehoiachin of Judah and released him from prison.
