"The traditional "Al Het" confessional prayer on Yom Kippur is a chance for the community to confess their sins together. This ritual, which can be performed during the month of Elul or during the high holidays, asks participants to think differently about guilt, to think about guilt that is placed on us by outside forces." (source)

"A new Al Het is inserted a few pages after the Martyrology during the Musaf with particular reference to the Holocaust." (source)

"Al Ḥet contains a list of sins in alphabetical order, two sins being allotted to every letter." (source)

"A custom associated with Al Chet is to beat the heart while saying the words al chet." (Glinert)
