Pascha Annotinuum

Pascha Annotinuum is an expression which was used in the Church of the early Middle Ages to designate the first anniversary day of baptism, which was observed by prayer and song by the baptized and his friends. It passed out of date in the 11th century, and the frequent efforts to re-establish the "Pascha annotinumn" have failed. The Sunday Quasimodogeniti was the day appointed for such observance, and was therefore principally called Pascha or Pascha Annotinum.
