Wednesday in the Octave of Easte
“The Liturgy of Easter Week indicates that every day within the Octave is treated the same as the original solemnity of Easter. The Liturgy of the Hours repeats the prayers for Sunday Week I every day of the octave for Lauds (Morning Prayer) and Vespers (Evening Prayer). The Responsory for Lauds, Vespers and Compline (Night Prayer) is replaced by Psalm 118:24, often referred to as the Easter psalm: ‘This is the day the Lord has made; let us be glad and rejoice in it.’ In the Mass, the same verse is used for the Alleluia for the Ordinary Form, and the Extraordinary Form this verse is the Gradual all week.”
