[7] The 1962 Roman Missal (still in limited use today) refers to this Sunday as Dominica in albis in octava Paschæ.
The name Quasimodo (or Quasimodogeniti) originates from the incipit of this day's traditional Latin introit,[4] which is based on 1 Peter 2:2.
The word "low" may serve to contrast it with the "high" festival of Easter on the preceding Sunday.
Five years later, Pope John Paul II died the evening before Divine Mercy Sunday, on Saturday, April 2, 2005.
[12] In the Catholic Church, special Divine Mercy celebrations often take place on this day, and the Sacrament of Reconciliation is often administered.
[13] The Italian feast of Our Lady of the Hens[14][15][16][17] and the Chilean Cuasimodo [es] festival[18] are held on this day.
