Each year the Secretariat of Divine Worship of the United States Conference of Catholic Bishops publishes the Liturgical Calendar for the Dioceses of the United States of America. This calendar lists each day's celebration, rank, liturgical color, citations for the Lectionary for Mass, and Psalter cycle for the Liturgy of the Hours. It is primarily used by authors of ordines and other liturgical aids published to foster the celebration of the  liturgy in our country, but may also be used by anyone who downloads a  copy.

The calendar is based upon the General Roman Calendar, promulgated by  Pope Saint Paul VI on February 14, 1969, subsequently amended by the  Holy See, and the Proper Calendar for the Dioceses of the United States  of America, approved by the USCCB and confirmed in 2010 by the  Congregation for Divine Worship and the Discipline of the Sacraments.
