The twelfth Jewish month is Elul, which is a four-letter word. Elul is the sixth month of the Jewish calendar and is usually observed in August or September. It is a time of preparation for the High Holidays of Rosh Hashanah and Yom Kippur. During Elul, Jews are encouraged to reflect on their actions and repent for any wrongdoings. Additionally, it is customary to blow the shofar, or ram's horn, every day during Elul as a call to repentance.
