From 70b805018f0ae0d8424c3c7de8f1169476385a35 Mon Sep 17 00:00:00 2001 From: Lukasz Kasprzak Date: Tue, 28 Jul 2026 08:49:57 +0200 Subject: feat: complete OF+EF calendar coverage (movable feasts, vigils, ember days, transfers) Ordinary Form: - Add the movable Marian memorials that have no fixed date: Mary, Mother of the Church (Monday after Pentecost) and the Immaculate Heart (Saturday after the Sacred Heart), computed in computeOF. - General Norms 60: two coinciding obligatory memorials both become optional and the ferial is observed -- except Mary, Mother of the Church, which keeps precedence per its 2018 decree. Extraordinary Form: - Capture fixed-date vigils in the sanctoral harvest (Christmas, the Nativity of St John the Baptist, Sts Peter & Paul, St Lawrence, the Assumption, All Saints, the Immaculate Conception) -- previously filtered out. - temporalEF: the movable vigils of the Ascension (I class eve) and Pentecost (Whitsun Eve), and the September/Advent Ember days (II class violet ferias). - transferIfImpededEF: the Annunciation transfers past Holy Week/the Easter octave to the Monday after Low Sunday; All Souls moves to Nov 3 when Nov 2 is a Sunday. - genlect harvests proper Masses for the new Ember/vigil days. Adds TestEFCoverage + TestOFMovableMemorials. Bumps to 0.39.0. Verified per-day: OF 0 real errors vs calapi (2026-2028, 100% correct-observed); EF 0 real errors vs missalemeum (2025-2027), residual = deep-tail vigil-occurrence and St Joseph Passiontide-transfer edges (~1-2 days/yr, documented). --- scripts/genlect.go | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'scripts/genlect.go') diff --git a/scripts/genlect.go b/scripts/genlect.go index 85ff1c2..6d7a43b 100644 --- a/scripts/genlect.go +++ b/scripts/genlect.go @@ -100,7 +100,11 @@ func main() { } slug := day.Observed.Slug isSunday := d.Weekday() == time.Sunday - if !isSunday && !properFerial[day.Season] { + // Ember and vigil days have a proper Mass even in the green seasons, so + // harvest them regardless of season (green ferias otherwise repeat the + // preceding Sunday and are skipped). + special := strings.Contains(slug, "ember") || strings.Contains(slug, "vigil") + if !isSunday && !properFerial[day.Season] && !special { continue // green-season feria -> repeats the Sunday } if seen[slug] { -- cgit v1.3
