Not required day of remembrance
The term non-mandatory day of remembrance (memoria ad libitum) , usually abbreviated in liturgical books with a "g", describes in the current liturgical calendar of the Catholic Church the celebration of a commemoration of a saint, which at the discretion of the celebrant or the rector of the church in Holy Mass and can be celebrated in community in the Liturgy of the Hours . In contrast to this, solemn feasts , feasts and due days of remembrance are always to be celebrated, as long as they are not displaced by a higher-ranking day of the liturgical hierarchy .
This classification was in the context of the liturgical reform with the reorganization of the church year and the Roman general calendar after the Second Vatican Council on February 14, 1969 by the Motu proprio Mysterii paschalis of Pope Paul VI. approved and entered into force on January 1, 1970. It replaced a differentiated hierarchy of liturgical celebrations that had been in effect since the 16th century.
Often saints who are less known in the room concerned are honored by non-mandatory days of remembrance . In part it is also about saints whose life is historically barely comprehensible, but whose veneration is desired due to the rich legends and whose liturgical celebration is to be made possible in this way; in the regional calendar of the German-speaking area these are about the hll. Georg (April 23), Barbara (December 4) and Nikolaus (December 6).
