About

The **Fast of Ninth of Av**, observed on **August 15**, is a solemn Jewish day of fasting, remembrance, and reflection. Known as Tisha B’Av, it commemorates the destruction of the First and Second Temples in Jerusalem, as well as other tragedies that have affected the Jewish people throughout history.

During this observance, many people refrain from eating and drinking, set aside ordinary comforts, and spend time in prayer, mourning, and the study of sacred texts. Although it is a day of sorrow, the Fast of Ninth of Av also invites compassion, resilience, and hope for healing and peace.

History

The **Fast of Ninth of Av**, observed on **August 15**, is a major Jewish day of mourning commemorating a series of calamities traditionally associated with the ninth day of the Hebrew month of Av. Its central historical focus is the destruction of the First Temple in Jerusalem by the Babylonian forces in 586 BCE and the destruction of the Second Temple by the Romans in 70 CE. Jewish tradition also connects the day with other national tragedies, including the expulsion of Jews from England in 1290 and from Spain in 1492.

The observance developed from ancient mourning practices surrounding the destruction of Jerusalem and the Temple. Over time, rabbinic Judaism expanded its meaning so that it recalled not only the two Temple destructions but also exile, persecution, war, and the loss of Jewish sovereignty. Accounts in the Hebrew Bible, the Talmud, and later Jewish historical writings helped establish the day as a collective remembrance of suffering and the consequences of internal division.

On August 15, observance traditionally centers on a complete fast, abstention from food and drink, and restrictions resembling those observed during mourning. Many worshippers attend synagogue services, sit on low stools or the floor, and read the biblical Book of Lamentations, known as *Eikhah*, along with other lamentations and passages describing catastrophe. Customs may also include avoiding celebratory activities, wearing non-leather footwear, and refraining from certain forms of personal comfort.

The Fast of Ninth of Av has therefore remained both a historical commemoration and a period of ethical reflection. Its themes include grief for destroyed communities, the enduring effects of displacement, and the hope that mourning can lead to renewal and reconciliation. For many Jewish communities, the observance on August 15 connects ancient history with later experiences of persecution while preserving memory as an important part of religious and cultural identity.
