COMPUTUS, ECCLESIASTICAL. The effort of many Christian writers to offer a certain basis for calculating the date of Easter led to the origin and development of ecclesiastical computus, which could be called a technical, mathematical and astronomical science aimed at exactly establishing the date of the spring equinox. This calculation proved to be particularly difficult, since both solar and lunar years needed to be taken into account. The date of Easter is fixed according to the lunar calendar: it is celebrated on the Sunday immediately after the first full moon of spring; but it is moveable according to the solar calendar, since the lunar year is shorter than the solar year by ca. 11 days and 6 hours. To keep this difference of length between the solar and lunar years from making the day of the first full moon of spring 14 Nisan according to the Jewish calendar slide indefinitely in relation to the solar calendar, an embolismic i.e. added month must be added to the lunar year at regular intervals. But this insertion displaces the correspondence between 114 Nisan and the days of the solar calendar; it was thus necessary to identify a cycle of solar and lunar years which allowed the cyclical recurrence of the dates of Easter in the same order and on the same days.
