2 [One in mourning] for all [other] dead may enter a house of feasting after thirty days; for his father and mother [not] until after twelve months [of mourning]. And even if the year is a leap year, he is permitted [to enter a house of feasting] after twelve months. However, [in the case of] a joyous entertainment of companions, which he [the mourner] is obliged to reciprocate forthwith, he is permitted to hold it immediately after the seven days; but if he is not obliged to reciprocate it, he is forbidden to enter [the place of such entertainment] until thirty days; and [one in mourning] for his father or mother, even if he is obliged to reciprocate it, he is forbidden until after twelve months. Rema: And in [ the case of ] a group [ gathered ] for a religious purpose, e.g., one [ a mourner ] who gives away in marriage a male or female orphan [ thus performing a religious act ] for the sake of heaven, and should he not eat there, [ his meritorious ] act might become suspended, — [ the law is that ] he is permitted [ to join in the festivities ] after thirty [ days ]; but within the thirty [ days of mourning ], he is forbidden [ to join ] in any feast whatsoever that is connected with a religious deed. However, he may enter [ to join in ] a feast that is connected with a religious act that has no joyous entertainment, e.g., the redemption of the [ firstborn ] son, or a feast of circumcision, [ in which case ] he is permitted to eat there, even during the seven [ days of mourning ], provided he does not leave the door of his house; but there are some who prohibit [ this ] in [ the case of ] a feast of circumcision. The accepted practice, however, is, not to eat at any feast whatsoever, for the entire twelve months [ of mourning ], — if it is outside of his home; and in his home we adopt the lenient view, [ viz.,] that he may eat in his home at a feast of circumcision, and much more so at other feasts that have no joyous entertainment; but in [ the case of ] a marriage-feast the stringent view should be adopted. Thus seems to me [ to be the correct view ]. A mourner who is a Sandek or a Mohel may wear Sabbath garments until after the circumcision, and he is permitted to enter a circumcision ceremony [ and ] to eat there, if it is after the thirty [ days of mourning ], although the circumcision does not [ take place ] in his home.
