5. A person commemorating a yahrzeit and, similarly, a person observing the
thirty days of mourning have priority over other mourners who are in the

Kaddish d'rabbonon and the Kaddish after Oleinu be given to the person
commemorating a yahrzeit or the person observing the thirty days of
mourning, while the other Kaddishim should be divided among the other
mourners if their number equals the number of the Kaddishim.
6. A person observing the thirty days of mourning is granted priority over

thirty days of mourning will not be left with a single Kaddish. [Thus is

commemorating the yahrzeit recited Kaddish today, his opportunity will have
