On the Hebrew calendar, Elul is the sixth month of the year. On the 10th day of last month – the month of Av – we began the Season of Comfort. The season of comfort continues seven weeks, until the first day of next month, which is Tishrei 1, the same day as the Feast of Trumpets. So we have seven weeks in the Season of Comfort, Av 10 to Tishrei 1.
Elul 1 also marks 40 days until the Day of Atonement (Yom Kippur), which is always on Tishrei 10.
