Where this comes from

Computed by Bless from the US Lectionary cycle — confirm with your parish.

Psalm citations keep the Hebrew numbering the US Lectionary prints; the chapter links open the CPDV, which numbers the Psalms as the Vulgate does (Psalm 85 there is Psalm 84). The calendar is the US one; seasons, colors and ranks are as Bless ships them, with known data errors corrected.
