Mourner’s Kaddish is a central prayer in Jewish liturgy for one in mourning, although it makes no mention of death. Rather it is about God’s greatness and is a variation on the Kaddish recited at every service.
For someone who has lost a parent, this prayer is traditionally said at daily minyan, every day for a year. For the loss of a spouse, sibling or child, it is recited for 30 days.
One requires a minyan to recite the Mourner’s Kaddish, hence the importance of maintaining our daily minyan.
