Charles Spurgeon Commentary Haggai 1:14-15

"And Jehovah stirred up the spirit of Zerubbabel the son of Shealtiel, governor of Judah, and the spirit of Joshua the son of Jehozadak, the high priest, and the spirit of all the remnant of the people; and they came and did work on the house of Jehovah of hosts, their God, in the four and twentieth day of the month, in the sixth [month], in the second year of Darius the king." — Haggai 1:14-15 (ASV)

And the LORD stirred up the Spirit of Zerubbabel the son of Shealtiel, governor of Judah, and the spirit of Joshua the son of Josedech, the high priest, and the spirit of all the remnant of the people; and they came and did work in the house of the LORD of hosts, their God, in the four and twentieth day of the sixth month, in the second year of Darius the king.

God takes note of the time when his people work for him; he records, in his almanac, the day, the month, the year, for he loves to see his people actively engaged in his service.
