The central worship service of the Orthodox Church, celebrating the Eucharist (Holy Communion). Usually celebrated on Sundays and feast days, the Divine Liturgy consists of the Liturgy of the Word (scripture readings) and Liturgy of the Faithful (Eucharistic prayer and communion). The most common forms are the Liturgies of St. John Chrysostom and St. Basil the Great.

The day before Palm Sunday, commemorating Christ raising Lazarus from the dead. This miracle foreshadowed Christ's own Resurrection and demonstrated His power over death. The service is joyful, anticipating the triumph of Palm Sunday and Pascha. Pussy willows are often blessed on this day in preparation for Palm Sunday.

The celebration of Christ's triumphal entry into Jerusalem, when crowds welcomed Him with palm branches. This feast begins Holy Week and is marked by the blessing and procession of palm branches (or pussy willows in northern climates). The service combines joy for Christ's kingship with anticipation of His upcoming Passion.

The Archangel Gabriel's announcement to the Virgin Mary that she would bear the Son of God. Celebrated on March 25th, exactly nine months before Christmas, this feast honors Mary's "Yes" to God's plan of salvation. The service emphasizes both the Incarnation of Christ and the Theotokos's role in our redemption.

The Last Supper of Christ with His disciples on Holy Thursday, when He instituted the Eucharist. Christ washed the disciples' feet, gave them His Body and Blood under the forms of bread and wine, and delivered His farewell discourse. This meal established the central sacrament of the Church and exemplified humble service. The Vesperal Liturgy of St. Basil is celebrated.

The commemoration of Christ's death on the Cross on Holy Friday. The Church observes this solemn day with the Royal Hours, Vespers with the procession of the Epitaphios (burial shroud), and Matins of Holy Saturday. This is a strict fast day. The services emphasize Christ's voluntary suffering for our salvation and His victory over death through death.

Brief prayer services traditionally celebrated at specific times of day: First Hour (6 AM), Third Hour (9 AM), Sixth Hour (noon), and Ninth Hour (3 PM). Each Hour includes psalms, troparia, and prayers appropriate to that time of day. These services sanctify the day and connect us to Christ's Passion, as they commemorate specific moments in His crucifixion and death.
