Each of the 12 Calendar pages accommodates one month and is decorated with gold initials decorated with punched dots and incised wavy lines on pink and blue grounds. Designed for use at the Benedictine Abbey of Peterborough, the Calendar includes an entry for local female Saints Kyneburga, Kyneswitha and Tibba (6 March). The manuscript must have been made after 1220 because the original scribe included two feasts first introduced in that year: the Translation of St Thomas of Canterbury (7 July) and the feast of St Hugh of Lincoln (17 November). An important Benedictine feast, the Octave of the Translation of St Benedict (18 July) was later erased.
