The day before Rosh Hashanah is known as Erev Rosh Hashanah in Hebrew ("Rosh Hashanah eve"). It falls on the 29th day of the Hebrew month of Elul, the day before the 1st of Tishrei. Some communities have the customs to perform Hatarat nedarim - a nullification of vows - after the morning prayer services during the morning of Erev Rosh Hashanah. The mood becomes festive but serious in anticipation of the new year and the synagogue services. Many Orthodox men have the custom to immerse in a mikveh in honor of the coming day.
