Movable Feast

Fixing Easter's date has caused controversy in Christendom over the years.

The First Council of Nicaea's exact words are not preserved from 325 but (gleaned from various sources) the Council ruled:
* that Easter must be celebrated by all throughout the world on the same Sunday;
* that this Sunday must follow the fourteenth day of the paschal moon;
* that the moon was to be accounted the paschal moon whose fourteenth day followed the spring equinox;
* that some provision should be made, probably by the Church of Alexandria as best skilled in astronomical calculations, for determining the proper date of Easter and communicating it to the rest of the world.

Easter, the first Sunday after the first full moon of the Spring Equinox, is preceded by the 40 days of Lent, and as a send off before penance and denial, there is Carnival.

Except in Monculi di Sopra. Owing to inclement weather before Ash Wednesday, this year Carnival will be next Sunday.

Whether they are shortening Lent or moving Easter is still unclear, but Nicaea's writ doesn't run here.

Their take on the Nicene Creed is yet to be put to the test.
