Special prayers for forgiveness recited on fast days, in the run up to Rosh Hashanah and during the 10 days of repentance between Rosh Hashanah and Yom Kippur.
Selichot (Heb. סליחות) are Jewish penitential poems and prayers, especially those said in the period leading up to the High Holy Days, and on Fast Days. The Thirteen Attributes of God are a central theme throughout the prayers.
