'Year' in the Bible

In the first year of Cyrus king of Persia, in order to accomplish the word of Yahweh by the mouth of Jeremiah, Yahweh stirred the spirit of Cyrus king of Persia and he sent a message to all of his kingdom and also [put the message] in writing:

In the second year after their coming to the house of God at Jerusalem, in the second month, Zerubbabel son of Shealtiel and Jeshua son of Jehozadak began [their work], and the remainder of their brothers the priests and the Levites and all who came from the captivity to Jerusalem. They appointed the Levites {from twenty years and older} to direct the work of the house of Yahweh.

Then the work on the house of God in Jerusalem stopped, and was discontinued until the second year of the reign of Darius king of Persia.

But in the first year of King Cyrus of Babylon's reign he issued forth a decree to build this house of God.

In the first year of King Cyrus, he issued forth a decree concerning the house of God in Jerusalem. Let the house be built, the place where sacrifices are offered and let its foundations be raised. Its height [shall be] sixty cubits and its width sixty cubits,

This house was completed on the third day of the month of Adar, which was in the sixth year of the reign of King Darius.

Some of the {Israelites}, some priests and Levites, the singers, the gatekeepers, and the temple servants went up to Jerusalem in the seventh year of King Artaxerxes.

He came to Jerusalem in the fifth month, which was in the seventh year of the king.
