All religions enshrine their truths in calendars. Eugen Rosenstock-Huessy.
This is one of the many 'rhyming' 7x7s that should be followed as one goes through the 'year'--or 'coram': Celebration Of Resurrection Anno Mundi. For instance, we rhyme the time(s) from Creation through A. D. 70, Psalms (twice), etc. Beatitudes, Days of Creation, Churches down the side. More. Thanks, @Doug Roorda.
