Services are held in the home, because mourners are not expected to leave their home during shiva, nor dress for public display. Shacharit is said in the morning, Mincha in the late afternoon and Maariv in the evening. A Minyan (10 people required for certain prayers) is needed in order to conduct the prayer services and it is customary for people to call upon the family at these times. At the end of each service the Mourners Kaddish is recited.
Shloshim means thirty, and identifies the thirty days after the death. Mourners are expected to limit their social activities and should not cut their hair or shave during this 23 days period after shiva.
The last of shiva is observed for only a few short hours. Comforters are expected to say to the mourners:
No more will your sun set, nor your moon be darkened, for God will be an eternal light for you, and your days of mourning shall end. (Isaiah 60:20)
Like a man whose mother consoles him, so shall I console you, and you shall be consoled in Jerusalem. (Isaiah 66:13)
Mourners then get up and go outside for the first time since the funeral, and take a short walk around the block.
