Octave of Easter spans eight days starting on Easter Sunday and ending the Second Sunday of Easter, which is also Divine Mercy Sunday. Every day of the Octave is a Solemnity, the Church’s highest feast day. We light the tall, white, decorated Pascal candle. We sing the Gloria, hear a special Easter Alleluia verse, and may recite the Easter Sequence before the Gospel. The priest uses an Easter preface. We also repeat “Alleluia” after we say the final “Thanks be to God” at the end of Mass. The priest’s vestments are white or gold, for both the Octave and the Easter season.
