1,323. Timely Notification
205:9 Some people have the practice to fast on the day a Torah scholar dies.
206:1 If a person learned of the death of a close relative for whom he is required to mourn within 30 days of the relative's passing, even on the thirtieth day itself, this is considered timely notification and the mourner tears his garment. He must then observe the seven-day mourning period (shiva) and the 30-day mourning period (shloshim) counting from the day he received the news. The day he received the news has all the same laws for him as the day of the burial. The 30 days in which the news is considered timely are counted from the day of the burial and not from the day of the deceased's passing.
