One of the things I love about the week after Easter is that the Church relates to each day of the octave as though it is Easter Day.  In the Preface of Easter I, the priest is directed to pray during the octave: “We praise you with greater joy than ever on this Easter day when Christ became our paschal sacrifice.”  (Unfortunately most of the priests where I attend daily Mass pray “in this Easter season.”)  In the Liturgy of the Hours, we pray Morning, Evening, and Night Prayer of Easter Day all week.  To me this is a foretaste of heaven when each day will be as the first.  “This is the day the Lord has made.  Let us be glad and rejoice in it!”
