Haggai 2:1

The Lord revealed another message, an oracle of encouragement, to Haggai almost one month later, on the twenty-first day of the seventh month (Tishri, modern October 17) of the same year, 520 B.C. This was the last day of the feast of Tabernacles (Booths). Tishri was a month of celebrations for the Israelites. On the first of this month they celebrated the feast of Trumpets, and on the tenth, the day of Atonement. The feast of Tabernacles lasted seven days, and the following day was a day of rest (Leviticus 23:33-44).
