The Septuagesima season always begins with the ninth week before Easter and includes three Sundays called respectively Septuagesima, Sexagesima, and Quinquagesima. These names which were borrowed from the numeral system of the time, denote a series of decades working back from the commencement of Lent, which is known in Latin as Quadragesima. [As the intervals between these Sundays only consist of seven days it is evident that this name must not be taken in a strictly arithmetical sense; but whereas Quadragesima comes exactly at the closing day of the 4th decade before Easter, Quinquagesima (47 days) falls within the 5th decade, Sexagesima (54 days) within the 6th, Septuagesima (61 days) within the 7th.]

This liturgical period is a prelude to Lent and a remote preparation for Easter. It serves as a time of transition for the soul, which must pass from Christmas joys to the stern penance of the sacred forty days. Even if the fast is not yet of obligation, the color of the vestments worn is already violet. As during Advent, the recital of the Gloria in excelsis is suspended, since this hymn which celebrated Christ’s birth in our mortal flesh, is reserved to extol Him when born in His undying Body, i.e. when He rises from the tomb. “Born once of the Virgin, thou art now reborn from the sepulchre,” will then be the cry of the Church. Again the Martyrology introduces Septuagesima Sunday as that on which “we lay aside the song of the Lord which is Alleluia.” “How,” said the people of Israel, “shall we sing the song of the Lord in a strange land?”

This “strange land” is for the people of Christ, the world, which is a place of exile, while Alleluia, the chant St. John heard in heaven, will begin again in the liturgy at Paschaltide, which represents the future life. In the Easter festivities we shall hail our Lord, the conqueror of Satan, who while freeing us from the bondage of sin, will re-open to us the heavenly kingdom. The season of Lent which lasts for forty days (Quadragesima) and that of Septuagesima which is made up of the following periods of ten days (Quinquagesima, Sexagesima, and Septuagesima) may well be taken as representing the seventy years passed by Israel in exile under the harsh captivity of the Babylonians. The chant of Alleluia is silent during this period in which the spirit and very name remind us so strongly, that we are “poor banished children…mourning and weeping in this vale of tears” (Salve Regina).

The Season of Septuagesima ends in the Temporal Cycle on Ash Wednesday. In the Sanctoral Cycle its extreme limit is March 10, that is, when Easter falls on April 25.
