By the provisions of the Book of Common Prayer, the weekdays of the Easter Octave (the week from Easter Day through the Second Sunday of Easter), like the days of Holy Week, take precedence over any commemorations on fixed dates. Thus, the commemorations of Dietrich Bonhoeffer, Pastor and Theologian (April 9 – William Law, Presbyter, is also commemorated in some sanctoral calendars on this date); and of George Augustus Selwyn, Bishop of New Zealand April 11), and of Litchfield will not be celebrated this year.
If you have not already been following them, the appointed propers for the days of the Easter Octave (Easter Week) are published on the Lectionary Page website.
