Editing Holy day of obligation (section)

==Eastern Catholic Churches==
The [[Code of Canons of the Eastern Churches]] (CCEO) lays down the relevant norms regarding holy days of obligations for [[Eastern Catholic Churches]]. There are five holy days of obligation, beyond Sundays, specified as common to all of the Eastern Churches:<ref>{{cite web|url=http://www.intratext.com/IXT/ENG1199/_POG.HTM|title=Canon 880 §3}} The relevant canon specifies the feasts by name and does not assign their celebration to a particular calendar date.</ref>

*The [[Solemnity of the Nativity of the Lord]] ([[Christmas]])
*The [[Epiphany (Christian)|Epiphany]]
*The [[Feast of the Ascension|Ascension]]
*The [[Feast of Saints Peter and Paul|Holy Apostles Peter and Paul]]
*The [[Dormition of Holy Mary, the Mother of God]]

The CCEO provides that only the "[[pope|supreme authority]]" of the Church can "establish, transfer or suppress feast days and days of penance which are common to all of the Eastern Churches," although the particular law of a ''sui juris'' Church can suppress one of these days or transfer it to Sunday, provided that said particular law has been approved by the Apostolic See.<ref name="auto">{{Cite web|url=http://www.intratext.com/IXT/ENG1199/_POG.HTM|title=CCEO: text - IntraText CT|website=www.intratext.com|accessdate=25 March 2023}}</ref> The authority competent to establish the particular law of a ''sui iuris'' Church may constitute, transfer, or suppress other feast days and days of penance (i.e., ones that are not common to all the Eastern Churches), under certain conditions.<ref name="auto"/>

The faithful of the Eastern Catholic Churches "are bound by the obligation to participate on Sundays and feast days in the Divine Liturgy or, according to the prescriptions or legitimate customs of their own Church sui iuris, in the celebration of the divine praises."<ref>{{Cite web|url=http://www.intratext.com/IXT/ENG1199/_POH.HTM|title=CCEO: text - IntraText CT|website=www.intratext.com|accessdate=25 March 2023}}</ref>
