Good Friday

The Monastic Diurnal sets out the Office as it is said today at 309*ff.  Note that:
 There are no opening prayers
 The Gloria Patri is not said at the end of each psalm
 The psalms etc for Prime to None are set out at MD 279* ff
 ‘Mortem autem crucis’ is added to the antiphon Christus factus est, MD 282*; and
 Compline as for Maundy Thursday, MD 305*

Remember, too, that if you attend the Good Friday afternoon liturgy, you do not need to say Vespers.

Note that outside of monasteries, Tenebrae of Holy Saturday is often anticipated, said after Compline rather than early in the morning.
