Our best-loved calendar. The stunning 2017 Mary and the Saints Catholic Wall Calendar is designed to suit every taste and inspire greater devotion to the Blessed Mother every day of the year. TAN Calendars contain special feasts and fascinating Catholic traditions. They are marked with days of Fasting, Special Days, and the Sundays of the Liturgical Year for both the Ordinary and the Extraordinary Calendar. The 12x12 Wall Calendar allows ample space for personal notes, appointments and special occasions. Filled with gorgeous Old Master artwork, meditations and prayers each image is hand chosen and designed with love and attention to detail.
