The Three Weeks

Just as mourners may not greet others, so too, one may not greet others on Tisha Be-Av.

Just as a mourner may not study Torah during the shiva period, one may not study Torah on Tisha Be-Av, so that one’s attention is not diverted from the mourning.

The fifth way in which we afflict ourselves on Tisha Be-Av is by abstaining from sexual relations.

One may not wear high-quality shoes on Tisha Be-Av. There is a dispute among the poskim about the status of non-leather shoes.

One may not apply oil or ointment on Tisha Be-Av even to a small area of the body. One may not smell perfumes or other fragrances on Tisha Be-Av.

One may wash one’s hands for the sake of a mitzva because such washing is not for the purpose of gaining pleasure.

sick people are exempt from fasting on Tisha Be-Av, while pregnant and nursing women – despite the aches and pains that they experience – are not considered sick.

Any form of pleasurable washing is prohibited on Tisha Be-Av, whether the water is hot or cold. One may not even wash a small part of his body.

Sick people are exempt from fasting on Tisha Be-Av. A woman within thirty days of childbirth is considered sick.Those who are exempt from fasting should take care to eat only simple foods that they need for their health.

There are few halakhic differences between Tisha Be-Av and the minor fasts. In general, the fast of Tisha Be-Av is equivalent to the fast of Yom Kippur.
