'Day' in the Bible

In the second year of Darius the king, in the sixth month, on the first day of the month, came the word of the Lord by Haggai the prophet to Zerubbabel, the son of Shealtiel, ruler of Judah, and to Joshua, the son of Jehozadak, the high priest, saying,

On the twenty-fourth day of the month, in the sixth month, in the second year of Darius the king.

In the seventh month, on the twenty-first day of the month, the word of the Lord came by Haggai the prophet, saying,

On the twenty-fourth day of the ninth month, in the second year of Darius, the word of the Lord came by Haggai the prophet, saying,

And now, give thought, looking back from this day to the time before one stone was put on another in the Temple of the Lord:

And now, give thought; looking on from this day, from the twenty-fourth day of the ninth month, from the time when the base of the Lord's house was put in its place, give thought to it.

Is the seed still in the store-house? have the vine and the fig-tree, the pomegranate and the olive-tree, still not given their fruit? from this day I will send my blessing on you.

And the word of the Lord came a second time to Haggai, on the twenty-fourth day of the month, saying,

In that day, says the Lord of armies, I will take you, O Zerubbabel, my servant, the son of Shealtiel, says the Lord, and will make you as a jewelled ring: for I have taken you to be mine, says the Lord of armies.
