Shabbat is primarily a day of rest and spiritual enrichment. The word "Shabbat" comes from the root Shin-Beit-Tav, meaning to cease, to end, or to rest.
"Mourners Kaddish" is said at all prayer services and certain other occasions. It is traditionally recited several times, most prominently at or towards the end of the service, after Aleinu and/or closing Psalms. Following the death of a child, spouse, or sibling it is customary to recite the Mourners' Kaddish in the presence of a minyan (ten Jewish adults) daily for thirty days. In the case of a parent, an adult child recites the Mourner’s Kaddish in the presence of a minyan (ten Jewish adults) for eleven months and then at every yahrzeit (anniversary of the death) and during the Yizkor services that take place on certain days of Jewish holidays.
Customs for reciting the Mourners Kaddish vary markedly among various communities. In Sephardi synagogues, the custom is that all the mourners stand and chant the Kaddish together. In Ashkenazi synagogues, the earlier custom was that one mourner be chosen to lead the prayer on behalf of the rest, though most congregations have now adopted the Sephardi custom. In some congregations (especially Reform and Conservative ones), the Rabbi will read a list of those who have a Yahrzeit on that day (or who have died within the past month).
It is important to note that the Mourners Kaddish does not mention death at all, but instead praises God. Though the Kaddish is often popularly referred to as the "Jewish Prayer for the Dead," that designation more accurately belongs to the prayer called "El Maleh Rahamim," which specifically prays for the soul of the deceased.
Kaddish D'Rabbanan is another form of the Mourner's Kaddish which may also be recited by anyone after the study of sacred texts as it contains a special prayer for the well-being of teachers, their disciples, and all who study Torah.
