'Of The Month' in the Bible

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

Then all the men of Judah and Benjamin gathered themselves together to Jerusalem within the three days; it was the ninth month, on the twentieth day of the month: and all the people sat in the broad place before God's house, trembling because of this matter, and for the great rain.
