Rosh Hashanah
At midnight on the Saturday night (Sunday morning) before Rosh Hashanah (or one week before that, if the first day of Rosh Hashanah is Monday or Tuesday), Ashkenazi Jews begin reciting "selichot". On the following days, however, they generally recite the "selichot" before the regular morning prayers. On the eve of Rosh Hashanah, extra prayers are recited and many fast until noon.
