'On that Day' in the Bible

He read from it facing the public square before the Water Gate from dawn until noon that day, opposite the men, women, and those with understanding. The ears of all the people [were attentive] to the book of the law.

They offered on that day great sacrifices and rejoiced because God brought great joy to them. And the women and children also rejoiced. The joy of Jerusalem was heard from afar.

On that day men were appointed for the storehouse rooms, the offerings, the first fruits, and the tithes, in order to gather in them from the fields of the cities the requirements of the law for the priests and Levites; for the joy of Judah [was] upon the priests and Levites standing there.

On that day the book of Moses was read in the hearing of the people and it was found written in it that no Ammonite or Moabite should ever come into the assembly of God
