Preparations for the Autumn Holidays begin a full month in advance. On the Jewish calendar is a forty-day season called Teshuvah (return or repentance.) It begins on Elul 1 and ends on the Day of Atonement (Tishri 10).

This forty-day season is a time for one to annually examine his life and restore relationships between God and man. The first thirty days of this season are the thirty days of the month of Elul. The last ten days of this forty-day season are the Feast of Trumpets and Day of Atonement, or the ten High Holy Days (Days of Awe).

The Jewish people start the celebration of the Autumn Holidays thirty days prior to the Feast of Trumpets, which falls on the first day of the seventh month.

For thirty days the shofar is blown every morning in the Synagogue to remind the people that the holy days are approaching, and that they should prepare themselves. Their preparation consists of confessing their sins and seeking forgiveness, and going back to fix mistakes made during the year. The ten days between the Feast of Trumpets and the Day of Atonement (Yom Kippur) are called the Days of Awe.
