Lazarákia are small, sweet spice breads made in Greece and Cyprus by Orthodox Christians on Lazarus Saturday, the Saturday that begins Holy Week. They are eaten to celebrate the miracle of Jesus raising Lazarus from the dead. They are shaped like a man wrapped in a shroud, supposedly Saint Lazarus of Bethany, with cloves for eyes. They contain several sweet spices and are a fasting Lenten food, meaning that they do not contain any dairy products or eggs. For that reason, unlike the tsourekia, they are brushed with olive oil instead of egg or butter for a gloss finish.

The Paschal Triduum, Holy Triduum, or Easter Triduum, or the Three Days, is the period of three days that begins with the liturgy on the evening of Maundy Thursday, reaches its high point in the Easter Vigil, and closes with evening prayer on Easter Sunday. It recalls the Passion, Crucifixion, Death, burial, and Resurrection of Jesus, as portrayed in the canonical Gospels. In the Anglican, Lutheran, Methodist, Moravian and Reformed traditions, the Paschal Triduum straddles the two liturgical seasons of Lent and Easter in the Church calendar ; however, in the Roman Catholic tradition, since the 1955 reform by Pope Pius XII, the Easter Triduum has been more clearly distinguished as a separate liturgical period. Previously, all these celebrations were advanced by more than twelve hours. The Mass of the Lord's Supper and the Easter Vigil were celebrated in the morning of Thursday and Saturday respectively, and Holy Week and Lent were seen as ending only on the approach of Easter. After the Gloria in excelsis Deo at the Mass of the Lord's Supper, all church bells are silenced and the organ is not used. The period that lasted from Thursday morning to before Easter Sunday began was once, in Anglo-Saxon times, referred to as "the still days". In the Catholic Church, weddings, which were once prohibited throughout the entire season of Lent and during certain other periods as well, are prohibited during the Triduum. Lutherans still discourage weddings during the entirety of Holy Week and the Easter Triduum.
