Great Lent, or the Great Fast, is the most important fasting season of the church year within many denominations of Eastern Christianity. It is intended to prepare Christians for the greatest feast of the church year, Pascha (Easter).
The liturgical year, also called the church year, Christian year or kalendar, consists of the cycle of liturgical seasons in Christian churches that determines when feast days, including celebrations of saints, are to be observed, and which portions of Scripture are to be read either in an annual cycle or in a cycle of several years.
Holy Week is the most sacred week in the liturgical year in Christianity. In Eastern Churches, which includes Eastern Orthodox, Eastern Catholic and Eastern Lutheran traditions, Holy Week occurs the week after Lazarus Saturday and starts on the evening of Palm Sunday. In the denominations of Western Christianity, which includes Roman Catholicism, Lutheranism, Moravianism, Anglicanism, Methodism and Reformed Christianity, it begins with Palm Sunday and concludes on Easter Sunday. For all Christian traditions it is a moveable observance. In Eastern Rite Churches, Holy Week starts after 40 days of Lent and two transitional days, namely Saturday of Lazarus and Palm Sunday. In the Western Christian Churches, Holy Week falls on the last week of Lent or Sixth Lent Week.
Septuagesima is the name for the ninth Sunday before Easter, the third before Ash Wednesday. The term is sometimes applied to the seventy days starting on Septuagesima Sunday and ending on the Saturday after Easter. Alternatively, the term is sometimes applied also to the period commonly called Shrovetide or Gesimatide that begins on this day and ends on Shrove Tuesday, the day before Ash Wednesday, when Lent begins.

Easter Vigil, also called the Paschal Vigil or the Great Vigil of Easter, is a liturgy held in traditional Christian churches as the first official celebration of the Resurrection of Jesus. Historically, it is during this liturgy that people are baptized and that adult catechumens are received into full communion with the Church. It is held in the hours of darkness between sunset on Holy Saturday and sunrise on Easter Day – most commonly in the evening of Holy Saturday or midnight – and is the first celebration of Easter, days traditionally being considered to begin at sunset.
Holy Monday or Great and Holy Monday is a day of the Holy Week, which is the week before Easter. According to the gospels, on this day Jesus Christ cursed the fig tree, cleansed the temple, and responded to the questioning of his authority.
The Paschal cycle, in Eastern Orthodox Christianity, is the cycle of the moveable feasts built around Pascha (Easter). The cycle consists of approximately ten weeks before and seven weeks after Pascha. The ten weeks before Pascha are known as the period of the Triodion, referring to the liturgical book that contains the services for this liturgical season. This period includes the three weeks preceding Great Lent, the "pre-Lenten period", the forty days of Lent, and Holy Week. The 50 days following Pascha are called the Pentecostarion, also named after the liturgical book.
Orthros or Útrenya, in the Byzantine Rite of the Eastern Orthodox Church and the Eastern Catholic Churches, is the last of the four night offices, the other three being vespers, compline, and midnight office. Traditionally, in monasteries it is held daily so as to end immediately following sunrise, in contrast to parishes where it is held only on Sundays and feast days. It is often called matins after the office it most nearly corresponds to in Western Christian churches.
In Eastern Orthodox and Byzantine Catholic churches, an entrance is a procession during which the clergy enter into the sanctuary through the Holy Doors. The origin of these entrances goes back to the early church, when the liturgical books and sacred vessels were kept in special storage rooms for safe keeping and the procession was necessary to bring these objects into the church when needed. Over the centuries, these processions have grown more elaborate, and nowadays are accompanied by incense, candles and liturgical fans. In the liturgical theology of the Eastern Orthodox Church, the angels are believed to enter with the clergy into the sanctuary, as evidenced by the prayers which accompany the various entrances.
Easter Saturday, on the Christian calendar, is the Saturday following the festival of Easter, the Saturday of Easter or Bright Week. In the liturgy of Western Christianity it is the last day of Easter Week, sometimes referred to as the Saturday of Easter Week or Saturday in Easter Week. In the liturgy of Eastern Christianity it is the last day of Bright Week, and called Bright Saturday, The Bright and Holy Septave Saturday of Easter Eve, or The Bright and Holy Septave Paschal Artos and Octoechoes Saturday of Iscariot's Byzantine Easter Eve. Easter Saturday is the day preceding the Octave Day of Easter.
In Christianity, the Nativity Fast—or Fast of the Prophets in Ethiopian Orthodox Tewahedo Church and Eritrean Orthodox Tewahedo Church—is a period of abstinence and penance practiced by the Eastern Orthodox Church, Oriental Orthodox Church and Catholic Church in preparation for the Nativity of Jesus on December 25. Ethiopian and Eritrean Orthodox Churches commence the season on November 24th and end the season on the day of Ethiopian Christmas which falls on 7th of January. The corresponding Western season of preparation for Christmas, which also has been called the Nativity Fast and St. Martin's Lent, has taken the name of Advent. The Eastern fast runs for 40 days instead of four or six weeks and thematically focuses on proclamation and glorification of the Incarnation of God, whereas the Western Advent focuses on three comings of Jesus Christ: his birth, reception of his grace by the faithful, and his Second Coming or Parousia.
Lazarus of Bethany, also venerated as Righteous Lazarus, the Four-Days Dead in the Eastern Orthodox Church, is the subject of a sign of Jesus in the Gospel of John, in which Jesus restores him to life four days after his death.

Bright Week, Pascha Week or Renewal Week is the name used by the Eastern Orthodox and Byzantine Rite Catholic Churches for the period of seven days beginning on Easter and continuing up to the following Sunday, which is known as Thomas Sunday.
The Gospel in Christian liturgy refers to a reading from the Gospels used during various religious services, including Mass or Divine Liturgy (Eucharist). In many Christian churches, all present stand when a passage from one of the Gospels is read publicly, and sit when a passage from a different part of the Bible is read.
