Our latest addition to the 2015 Calendars dedicated to the liturgical life of the Ancient Roman Rite (or "Extraordinary Form" of the Roman Rite) is the beautiful production of the Priestly Fraternity of Saint Peter (FSSP).
In 2015, this Traditional Latin Mass calendar is dedicated to the glories of the Faith (great for teaching Catholic history to the littlest Catholics) and it offers two new aspects compared with other years: a larger space for writing on each day and a clearer listing of the days of penance and abstinence in the current law, along with the laws of partial and complete fast and abstinence as it was ordered in 1962, and as can be followed by the faithful today for their personal edification.
The Calendar is sold for a very reasonable $13.00 (including domestic shipping for the United States), and you can find it here. Contact them for possible lower prices for bulk purchases, and if you are abroad they will notify you of any additional shipping charges after purchase.
[Note: as ALWAYS in Rorate, we get nothing from the products we promote, we do it for the greater glory of God - we have always refused ads and we have never asked for donations for ourselves.]
