Selichot or slichot (Hebrew: ???????) are Jewish penitential poems and prayers, especially those said in the period leading up to the High Holidays, and on Fast Days. God's Thirteen Attributes of Mercy are a central theme throughout these prayers. In the Sephardic tradition, recital of Selichot in preparation for the High Holidays begins on the second day of the Hebrew month of Elul. In the Ashkenazic tradition, it begins on the Saturday night before Rosh Hashanah. If, however, the first day of Rosh Hashanah falls on Monday or Tuesday, Selichot are said beginning the Saturday night prior to ensure that Selichot are recited at least four times. This may be because originally the pious would fast for ten days during the season of repentance, and four days before Rosh Hashanah were added to compensate for the four of the Ten days of Repentance on which fasting is forbidden - the two days of Rosh Hashanah, Shabbat Shuvah, and the day preceding Yom Kippur - and, while the fasts have since been abandoned, the Selichot that accompanied them have been retained.
