In the annotation which identifies each saint, the first pair of numbers inidcates the month while the second pair indicates the exact day of the month referred to : thus, from 0101 for January 1st to 1231 for December 31st. The fifth symbol indicates the initial letter of the saint's name or of the feast day. When, on the same day, there is more than one saint or feast present beginning with the same letter, the sixth symbol indicates their position in the series. For example, on September 14th were celebrated - in manuscripts of varying periods and areas - the following feasts : for Pope Cornelius ; for the Roman martyr, Cresentius ; for the Exaltation of the Cross ; for the Bishop of Carthage, Cyprianus ; for the Calabrian martyr, Cassiodorus.

Here are the relative annotations :
0914C1 Cornelius pp
0914C2 Cresentius m Roma
0914C3 Crux - Exaltatio
0914C4 Cyprianus ep Cartagine
0914C5 Cassiodorus m Calabria

We would like to point out that the reference is to those saints and feasts found in manuscripts or books printed in past centuries - therefore independently of whether or not these are found in modern liturgical texts.
