Observance: The Three Weeks (July 4 - July 26)

Upcoming Observance: The Three Weeks

July 4 - 26, 2015

The Three Weeks is an annual mourning period that falls out in the summer. This is when the Jewish people mourn the destruction of the Holy Temple and our launch into a still-ongoing exile.

The period begins on the 17th of the Hebrew month of Tammuz (July 4, 2015), a fast day that marks the day when the walls of Jerusalem were breached by the Romans in 69 CE.

It reaches its climax and concludes with the fast of the 9th of Av (July 26, 2015) the date when both Holy Temples were set aflame. This is the saddest day of the Jewish calendar, and it is also the date of other tragedies spanning the Jewish nation’s history.


There are various mourning-related customs and observances that are followed for the entire three-week period (until midday of the 10th of the Hebrew month of Av, or—if that date falls on Friday—the morning of that day). We do not cut our hair, purchase new clothes, or listen to music. No weddings are held.

17 Tammuz (July 4, 2015) is a fast day, on which one refrains from eating and drinking from dawn to nightfall. Starting on the first of Av, we refrain from eating meat or drinking wine, and from wearing freshly laundered clothes.

9th of Av (July 26, 2015) is a more stringent fast than 17 Tammuz. It begins at sunset of the previous evening, when we gather in the synagogue to read the Book of Lamentations.
Besides fasting, we abstain from additional pleasures, like washing, wearing leather shoes, and marital intimacy. Until midday, we sit on the floor or on low stools. 

There is more to the Three Weeks than fasting and lamentation. It is taught that those who mourn the destruction of Jerusalem will merit seeing it rebuilt with the coming of the Jewish redeemer, and then all the mournful dates on the calendar will be transformed into days of tremendous joy and happiness.
