'Year' in the Bible

Now in the first year of Cyrus king of Persia [that is, the first year he ruled Babylon], in order to fulfill the word of the Lord by the mouth of Jeremiah [the prophet], the Lord stirred up (put in motion) the spirit of Cyrus king of Persia, so that he sent a proclamation throughout all his kingdom, and also put it in writing, saying:

In the second year of their coming to God’s house at Jerusalem, in the second month, Zerubbabel the son of Shealtiel and Jeshua the son of Jozadak began [the work], with the rest of their brothers—the priests and Levites and all who came to Jerusalem from the captivity. They appointed the Levites, from twenty years old and upward, to oversee the work of the house of the Lord.

Then the work on the house of God in Jerusalem stopped. It was suspended until the second year of the reign of Darius king of Persia.

But in the first year of Cyrus king of Babylon, [the same] King Cyrus issued a decree to rebuild this house of God.

In the first year of King Cyrus, Cyrus the king issued a decree: ‘Concerning the house of God in Jerusalem, let the temple (house), the place where sacrifices are offered, be rebuilt and let its foundations be strongly laid, its height and its width each 60 cubits,

This temple was finished on the third day of the month of Adar, in the sixth year of the reign of King Darius.

Some of the sons of Israel, with some of the priests and Levites, the singers and gatekeepers, and the temple servants also went up [from Babylon] to Jerusalem in the seventh year of King Artaxerxes.

Ezra came to Jerusalem in the fifth month of the seventh year of the king.
