The Catholic church designated a very large number of holy days. On such days the laity and the clergy were forbidden to work and obliged to attend mass. While the Church of England abolished many of these, there were still a large number of holy days, including all Sundays and all those days for which the Book of Common Prayer provides a proper collect, epistle and gospel reading in its calendar. They included the feasts of Circumcision (1 Jan.), Epiphany (6 Jan.), Ascension Day (5th Thursday after Easter), Corpus Christi, Saints Peter and Paul (29 June), Assumption of the Blessed Virgin Mary (15 Aug.), All Saints (1 Nov.) and Christmas Day. Many holy days had a civic, agricultural and/or economic significance.
