How the rule works
Ireland has six holy days of obligation besides Sundays, including Saint Patrick's Day (17 March), which is proper to Ireland. There is NO Saturday/Monday rule — the obligation binds on whatever weekday the feast falls (official ICBC practice: Monday All Saints 2004 and Monday Epiphany 2014 were fully observed). The Ascension and Corpus Christi are celebrated on Sundays.
Celebrated on Sunday in Ireland
These solemnities are transferred to a Sunday, so they are covered by the ordinary Sunday obligation:
- The Ascension of the Lord — Sunday, May 9. Celebrated on the Seventh Sunday of Easter in Ireland.
- The Most Holy Body and Blood of Christ (Corpus Christi) — Sunday, May 30. Celebrated on the Sunday after Trinity Sunday in Ireland.
Not days of obligation in Ireland
These feasts of canon 1246 are kept as solemnities on their dates, without a Mass obligation:
- Mary, the Holy Mother of God (1 January)
- Saint Joseph (19 March)
- Saints Peter and Paul (29 June)
Fasting & abstinence in Ireland
Ash Wednesday and Good Friday are days of fast and abstinence. Every Friday of the year is an obligatory day of penance in Ireland, but the Irish bishops allow it to be fulfilled by abstaining from meat OR by alternatives: giving up another food, drink or amusement, family prayer, attending Mass, visiting the Blessed Sacrament, the Stations of the Cross, extra fasting with almsgiving, or helping those in need (Irish Episcopal Conference Decree No. 14 and the 2010 Friday Penance resource).
Fasting binds those over 18 until the beginning of their 60th year; abstinence binds all over 14 (Decree No. 14 Appendix).
Friday penance lapses when a solemnity falls on a Friday (canon 1251).
