The seventh month, in autumn — and the busiest, holding Trumpets, Atonement and Tabernacles.
Tishri is the seventh month counting from spring, and the first of the civil year. Three of the appointed feasts fall inside it: Trumpets on the first, Atonement on the tenth, and Tabernacles from the fifteenth. Its older name in Kings is Ethanim. It is also when Solomon dedicated the temple, at the feast in the seventh month.
