12 saints for April (11 real + St. Catherine of Siena as a stub), all
winning outright on a clean per-annum date.
Two real methodological findings this month:
- St. Mark (Apr 25, Duplex II. classis) directly confirms the
privileged-feria-major behavior from the previous fix: he only ever
gets commemorated within the Easter Octave, never wins there.
- St. Robert/St. Catherine of Siena (Apr 29) is a genuine, year-stable
monastic-calendar reassignment — this app's own base Latin source data
files that date's Roman-calendar content under a different saint (Peter
Martyr) entirely, which a naive raw-file lookup by MM-DD would have
missed; the live per-date query resolved it correctly regardless, and
is what these records are actually built from. Worth remembering for
future months.
New common category: common-of-an-evangelist (St. Mark, an Evangelist
but not an Apostle).
