The Ordo is of the celebrations observed in the abbeys of the Congregation. The Sundays and Easter Season usually take precedence over the days listed here. Feasts are called such in their title.
Memorials are in plain text.
Optional memorials are in italics. If they are not celebrated, the feria is kept instead. Ferial days are the ordinary days of the season in which they fall. In Lent and in the last eight days of Advent all memorials become optional commemorations and are shown in italics. By clicking on the Saint s name, a brief biography will be displayed, together with links to fuller biographies on the Web where possible.
