It is symptomatic of the completely different way in which we now approach both Sundays and octaves that the first entry for this week seems so surprising. The octave day of the Holy Innocents would normally be a feast day of three lessons; when it falls on a Sunday, far from being eclipsed by the proper office of the Sunday, it is simply celebrated with (marginally) greater solemnity.
