The Arizona Rosary Celebration is sponsored by the Knights of Columbus Arizona State Council. It is assisted by the Dioceses of Tucson and Phoenix, Legion of Mary, Catholic Daughters of America, and many other Lay Catholic organizations.
For 42 years, the Diocese of Phoenix has hosted one of the largest annual public rosary celebrations in the United States. Eight years ago, the Arizona Rosary Celebration established the Rosary Sunday tradition within the Diocese of Tucson. This major celebration in honor of Our Lady is sponsored by the Arizona Knights of Columbus and now held in conjunction with the Dioceses of Tucson and Phoenix. Assistance is given by many groups and organizations, including the Legion of Mary and Catholic Daughters of America. Invitations to participate are being extended to all parishes and groups in each diocese.
