'Day' in the Bible

In the second year of Darius the king, in the sixth month, in the first day of the month, hath a word of Jehovah been by the hand of Haggai the prophet, unto Zerubbabel son of Shealtiel, governor of Judah, and unto Joshua son of Josedech, the high priest, saying:

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

And now, lay it, I pray you, to your heart, From this day, and onwards, Before the laying of stone to stone in the temple of Jehovah.

Set it, I pray you, to your heart, from this day and onwards, from the twenty and fourth day of the ninth month, even from the day that the temple of Jehovah hath been founded, set it to your heart.

Is the seed yet in the barn? And hitherto the vine and the fig, And the pomegranate, and the olive-tree, Have not borne -- from this day I bless.'

In that day -- an affirmation of Jehovah of Hosts, I take thee, Zerubbabel, son of Shealtiel, My servant -- an affirmation of Jehovah, And have set thee as a signet, for on thee I have fixed, An affirmation of Jehovah of Hosts!
