'Years' in the Bible

Now in the second year of their coming to the house of God at Jerusalem, in the second month, began Zerubbabel the son of Shealtiel, and Jeshua the son of Jozadak, and the rest of their brothers the priests and the Levites, and all those who were come out of the captivity to Jerusalem, and appointed the Levites, from twenty years old and upward, to have the oversight of the work of the house of Yahweh.

Thus they returned us answer, saying, "We are the servants of the God of heaven and earth, and are building the house that was built these many years ago, which a great king of Israel built and finished.
