Book excerpt: Companion to the Calendar, Second Edition has been revised to include the additional saints added to the proper calendar for the dioceses of the United States of America. While still including biographical information about the saints that are celebrated on the Roman Catholic liturgical calendar in the dioceses of the United States, the theological meaning of the various liturgical seasons, and explanations of secular days and Jewish and Muslim feasts, this Second Edition has also been revised to include additional Catholic days such as Marian and sanctoral observances, devotions from particular cultures (Hispanic, Vietnamese, etc), and other observances such as Catholic Schools Week and the World Day of the Sick.
