Holy Week is the most sacred week in the liturgical year in Christianity. For all Christian traditions, it is a moveable observance. In Eastern Christianity, which also calls it Great Week, it is the week following Great Lent and Lazarus Saturday, starting on the evening of Palm Sunday and concluding on the evening of Great Saturday. In Western Christianity, Holy Week is the sixth and last week of Lent, beginning with Palm Sunday and concluding on Holy Saturday.
The entry of Jesus and his disciples into Jerusalem on Palm Sunday marks the beginning of Holy Week, is the last week of Lent, between Palm Sunday and the dusk of Maundy Thursday. In the Eastern Orthodox Church, Palm Sunday along with the Saturday of Lazarus marks the two-day transition between the 40 days of Great Lent and Holy Week.
