Day Before Rosh Hashanah

The pre-Rosh Hashanah morning service has some extra features -- selichot and hatarat nedarim -- and is missing several features -- tachanun and the sounding of the shofar...

Visiting cemeteries, reciting Psalms, going to a mikvah, purchasing a knife -- some of the other customs associated with the day before Rosh Hashanah.

When a holiday runs directly into Shabbat, an eruv tavshilin is set aside before the holiday. This allows us to prepare on the holiday for the Shabbat that follows.
