Easter, also called Pascha, Zatik or Resurrection Sunday, is a Christian festival and cultural holiday commemorating the resurrection of Jesus from the dead, described in the New Testament as having occurred on the third day of his burial following his crucifixion by the Romans at Calvary c. 30 AD. It is the culmination of the Passion of Jesus, preceded by Lent, a 40-day period of fasting, prayer, and penance. Most Christians refer to the week before Easter as Holy Week, which in Western Christianity contains the days of the Easter Triduum including Maundy Thursday, commemorating the Maundy and Last Supper, as well as Good Friday, commemorating the crucifixion and death of Jesus. In Eastern Christianity, the same days and events are commemorated with the names of days all starting with “Holy” or “Holy and Great;” and Easter itself might be called “Great and Holy Pascha”, “Easter Sunday,” “Pascha” or “Sunday of Pascha.” Source: Duckduckgo API
