The Octave of Pentecost?

This morning I mused on our way to Mass that it seemed strange that there wasn't an Octave of Pentecost--given that it celebrates the coming of the Third Person of the Trinity. Well it turns out that there was an Octave, but that it disappeared in the 1960's, Father Mark has a post on this. Let us hope that Pope Benedict might restore this Octave as he calls upon the Church to experience a new Pentecost!
