ORDO is a perpetual liturgical calendar (until 2037) and a missal for the traditional Catholic rite.
It conforms to the 1962 liturgical calendar, centered around the Mass of Saint Pius V (in Latin).
For each day, you can find:
- The various feasts of the day,
- The proper texts for each day,
- The lives of the saints of the day.
- The Ordinary of the Mass including the texts for each day
- The choice of Mass form (read/sung)
- For sung Masses, the main Gregorian scores from the Kyriale
All information is in the application and is not downloaded from the Internet: it is therefore always available.
