Ecclesiastical Computation

ECCLESIASTICAL COMPUTUS. – It is defined by writers as: “knowledge of the course of the moon and of the kalends, or the science of determining time according to the course of the moon and the sun.” It comprises the information necessary for determining Easter, namely the nineteen-year, lunar, and solar cycles, the epacts, and the concurrent days. Charlemagne made it one of the subjects to be taught in schools. S. Beda the Venerable devoted two books of his didactic works to it (De temporum ratione and De ratione comput. Pl. 90, 295–578, 579–600).
