The Good Friday conflict is my mistake, I fear. I answered your post at
breakneck speed, and unfortunately, the gap between my brain and my fingers
proved more unbridgeable than usual. When I was doing this stuff
professionally, the Triduum of course began with the celebration of the Mass
of the Lord's Supper on Maundy [< `Mandatum'] Thursday, and concluded with
and at the celebration of the vigil of the Lord's resurrection, begun during
the hours of darkness of Holy Saturday/Easter Sunday (the timing of the
Easter Vigil varied, even in the modern period). This was both the
conclusion of the Triduum, and the beginning of the Octave of Easter. It is
an octave because it is believed that here time touches eternity, and
foreshadows the feast of the Kingdom.
Mea culpa, &c., and regards,

Thank-you all who came to my rescue. Alas, however, at the risk of seeming
ungrateful, I now have three (an appropriate number) conflicting
definitions, viz.,  Maundy Thursday through Easter Sunday (which
encompasses 4 rather than 3 days),  Good Friday through Easter Sunday,
and  Maundy Thursday through Holy Saturday. Since the last of these
definitions has the imprimatur of the _Oxford Dictionary of the Christian
Church_, I suppose that credential would give it the upper hand.
Nevertheless, I am confused. Help!
