Signed Robertus Card. +; Sarah (Praefectus) + Arturus Roche (Archiepiscopus a Secretis). +; Published: AAS 110 (2018), 437-438 (decree text continues past 438; +; index cites 437 as the start page). +; +; What it does, verified directly against the decree's own operative +; sentence (docs/research/of/aas-monthly/2018_marzo.pdf, line 2434-2437 of +; the extracted transcript): "Summus autem Pontifex Franciscus... decrevit +; ut memoriam B. Mariae Virginis, Ecclesiae Matris, in Calendarium +; Romanum inscribendam esse Feria II post Pentecosten et quotannis +; celebrandam" -- inscribes a MEMORIA (obligatory: no "ad libitum" +; qualifier anywhere in the operative sentence) on "Feria II post +; Pentecosten", the MONDAY AFTER PENTECOST. +; +; Date arithmetic, verified rather than trusted: Pentecost is Easter+49 +; (the 50th day of the Paschal season inclusive of Easter itself), so the +; following Monday is Easter+50. Date_spec.Easter_offset 50 is exactly +; this; kernel-level and rite-agnostic (built for EF's Rogation +; Wednesday), no code change needed. See test_amendments_of.ml's own +; test_mater_ecclesiae_monday_after_pentecost, which re-derives the +; calendar date from Colitur_kernel.Computus.gregorian_easter in three +; real years rather than trusting this offset's own arithmetic. +; +; The day carries no other GRC celebration to displace on any FIXED date +; -- but the decree's own destination is a MOVABLE one, so this is not +; quite true every year: see the finding recorded below. +; +; `la` name taken directly from the decree's own text ("B.

Verified +; computationally (Meeus/Jones/Butcher Gregorian Easter, 1583-2100) that +; Easter+50 DOES land on each of those dates in real years -- e.g. 2011 +; (Easter 24 April) puts Mary, Mother of the Church squarely on 13 June, +; Anthony of Padua's own day.
