Holy Week

Holy Week (Latin: Hebdomas Sancta or Hebdomas Maior, ``Greater Week''; Greek: Ἁγία καὶ Μεγάλη Ἑβδομάς, Hagia kai Megale Hebdomas, ``Holy and Great Week'') in Christianity is the week just before Easter. It is also the last week of Lent, in the West, - Palm Sunday, Holy Wednesday (Spy Wednesday), Maundy Thursday (Holy Thursday), Good Friday (Holy Friday), and Holy Saturday - are all included. However, Easter Sunday, which begins the season of Eastertide, is not. Although, traditions observing the Easter Triduum may overlap or displace part of Holy Week or Easter itself within that additional liturgical period.
