Yom Kippur, also known as the Day of Atonement, is the holiest day in Judaism and is observed annually on the 10th day of Tishrei, corresponding to a date in September or early October. It is a 25-hour solemn fast day during which Jewish people pray, seek forgiveness, and a fresh start both with God and their community. Yom Kippur is marked by abstention from food, drink, and sex, and some Orthodox Jews also refrain from wearing leather shoes and anointing themselves with oil. The day is characterized by private introspection and powerful communal connection, with confessional statements recited in the plural to seek forgiveness for sins committed collectively. Yom Kippur is a solemn day, but it is not a sad day, and it is a critical part of the Jewish year, offering five prayer services during which the congregation confesses its sins collectively. Some attendees wear white clothing or a kittel, a white garment that symbolizes a burial shroud, the clothing of angels, and the purity of forgiveness.
