Excerpt from Compotus Fratris Rogeri: Accedunt Compotus Roberti Grossecapitis Lincolniensis Episcopi; Massa Compoti Alexandri De Villa Dei

The need for a Computus arises from the difficulty of combining a calendar based on the movements of the moon with the use of a solar year, since the day, the lunar month, and the solar year are incommensurable, that is, no number of days will ever make an exact number of lunar months or solar years, and no number of lunar months will make an exact number of years. Any calendar must therefore be a compromise.

The Jewish Calendar is based on lunar months and a solar year, inserting an intercalary month when the difference of ten and seven - eighth days between twelve lunar months and a solar year has amounted to another month; the European Calendar is based on the old Roman one and is entirely solar, the months having no relation to the moon. Owing, however, to the definition of Easter adopted in the general practice of Christianity, the Church Calendar still depends on the movements of a hypothetical satellite - the ecclesiastical moon - which in the Middle Ages bore a rather distant relationship to the moon of the heavens, though in the reformed calendar the relation is designedly close.
