'Day' in the Bible

In the second year of King Darius, on the first day of the sixth month, the word of the Lord came through Haggai the prophet to Zerubbabel son of Shealtiel, the governor of Judah, and to Joshua son of Jehozadak, the high priest:

on the twenty-fourth day of the sixth month, in the second year of King Darius.

On the twenty-first day of the seventh month, the word of the Lord came through Haggai the prophet:

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

“Now, reflect back from this day: Before one stone was placed on another in the Lord’s temple,

“Consider carefully from this day forward; from the twenty-fourth day of the ninth month, from the day the foundation of the Lord’s temple was laid; consider it carefully.

Is there still seed left in the granary? The vine, the fig, the pomegranate, and the olive tree have not yet produced. But from this day on I will bless you.”

The word of the Lord came to Haggai a second time on the twenty-fourth day of the month:

On that day”—this is the declaration of the Lord of Hosts—“I will take you, Zerubbabel son of Shealtiel, My servant”—this is the Lord’s declaration—“and make you like My signet ring, for I have chosen you.” This is the declaration of the Lord of Hosts.
