By the 14th century most churches in England followed the so-called 'Use of Sarum', the liturgy established in the 13th century for use at Salisbury. Thus the textual contents of English liturgical manuscripts are generally uniform, and one has to look for small variations in order to identify where a book was used or made. The calendar of this Missal includes (along with the usual Use of Sarum entries) the dedication of the church of Colwich, between Stafford and Rugeley in Staffordshire; it must surely therefore have been used there. Liturgical books are often divided into a section for movable feasts, such as Advent Easter; and a section for feasts which always occur on the same day every year, such as saint's days. Because the first section begins with Advent, which begins between 27 November to a week later, the second section begins with St. Andrew, whose feast day is on 30 November.
