Just a reminder that Lent proper (so far as the Office goes!) starts this week (though as far as the number of penitential days goes, we have already completed four of the nominally forty days, but actually more like 36 by virtue of assorted Solemnities).
The Ordinary of the ferial Office in Lent is set out in the Farnborough edition of the Monastic Diurnal at MD 190*ff.
Each day there are two sets of collects: the first for use from Matins to None; the second for Vespers.
At Lauds and Vespers, chapters, hymns, etc of the season replace those in the psalter section;
and the canticle antiphons are proper for each day.
If you say one of those people who rise in darkness to say Matins, do enjoy the Sunday invitatory antiphon during this season: Non sit vobis vanum mane surgere ante lucem: Quia promisit Dominus coronam vigilantibus (it is not in vain that you rise before the light: for the Lord has promised a crown to those keeping vigil).
