During Holy Week, on Monday, Tuesday and Wednesday, the services are similar to those during Great Lent except there is no reading of Kathismata, and instead of the normal Lenten hymns which replace the Kontakion, the Kontakion of the day (i.e., that day of Holy Week) is chanted. On Great Thursday and Saturday, the Little Hours are more like normal, except that a Troparion of the Prophecy, prokeimena, and a reading from Jeremiah are chanted at the First Hour on Great Thursday. On Great Friday, the Royal Hours are chanted.
