We are now in a period of the Jewish calendar called the Three Weeks in English, Di Drei Wochen in Yiddish, and Bein Hametzarim in Hebrew.
If one reviews the laws and customs of the three weeks and/or the nine days leading up to Tisha B’Av in the Shulhan Aruch (Orah Haim 551), one finds the following prohibitions: joy, business deals, betrothal feasts and weddings, haircuts and shaving, laundry, wearing new clothes, eating meat and drinking wine, bathing, and reciting the sheheheyanu blessing over a new fruit or piece of clothing.
