After 1568, when Pope Pius V reduced the number of octaves, they were still numerous. Not only on the eighth day from the feast but on all the intervening days, the liturgy was the same as on the feast itself, with exactly the same prayers and Scripture readings. Octaves were classified into several types. Easter and Pentecost had "specially privileged" octaves, during which no other feast whatsoever could be celebrated. Christmas, Epiphany, and Corpus Christi had "privileged" octaves, during which certain highly ranked feasts might be celebrated. The octaves of other feasts allowed even more feasts to be celebrated.
