In the Roman Rite (pre-1970 form, and today in the Ordinariate Form and Extraordinary Form), and in similar Anglican and Lutheran uses, a pre-Lenten season lasts from Septuagesima Sunday until Shrove Tuesday and has thus also been known as Shrovetide. The Extraordinary form of the Roman Rite that includes this special period of 17 days refers to it as the season of Septuagesima; the Ordinariate Form uses the term Pre-Lent. The liturgy of the period is characterized by violet vestments (except on feasts), the omission of the Alleluia before the Gospel, and a more penitential mood. Fasting does not commence until the beginning of Lent on Ash Wednesday. The earliest the Pre-Lenten season can begin is January 18 and the latest it can end is March 9. It is absent in the Ordinary Form of the Roman Rite and more recent Anglican forms of all these traditions, but may be found in some Lutheran churches who use the One-Year Lectionary to organize the church year.
In Northern Germany, local tradition states that if "sausages and sauerkraut are eaten at Shrovetide, good luck will follow". On the last day of Shrovetide, in Bohemia, a man personifies "Shrovetide" in a procession of masqueraders and whoever is able to snatch straw from his hat and place it under a hen in the coming Spring is said to have eggs that surely will hatch.
In the Eastern Orthodox Church and those Eastern Catholic Churches which follow the Byzantine Rite, the pre-Lenten season lasts three weeks, beginning on the Sunday of the Publican and the Pharisee and continuing through the Sunday of Forgiveness (the day before the beginning of Great Lent). Since the liturgical day begins at sunset, and Great Lent begins on a Monday, the point at which Great Lent begins is at Vespers on the night of the Sunday of Forgiveness, with a "Ceremony of Mutual Forgiveness" (in some monasteries, this ceremony is performed at Compline instead of Vespers). Thus begins the first day of the Great Fast, which is known as Clean Monday. The weeks of pre-Lent and Great Lent are anticipatory by nature; they begin on Monday and end on Sunday, each week being named for the theme of the upcoming Sunday. The hymns used during the Pre-Lenten and Lenten seasons are taken from a book called the Triodion.
