Principal Holy Day (Anglicanism)
Principal Holy Days are a type of observance in the Anglican Communion, including the Church of England. All Principal Feasts are also Principal Holy Days.  All Principal Holy Days share equal status; however those which are not Principal Feasts, being fast days within the season of Lent, lack a festal character.  They are considered to be the most significant type of observance, the others being Festivals, Lesser Festivals, and Commemorations. Observance of Principal Holy Days is considered obligatory.
