Ping... as promised.
I'm not sure where you're going with that one.
I am aware of 8 canonical hours: prime. lauds, terce, sext, none, vespers, compline, matins.
Prime was surpressed with the current General Instruction of the Liturgy of the Hours. Matins was changed from being strictly at midnight into being the Office of Readings, which can be accomplished at any time.
Ps 119:164 Seven times a day I praise thee for thy righteous ordinances.
Otherwise, it looks like a good test!
