The following plan is taken from the Psalter in the Book of Common Prayer. This is not original, but I wanted to provide a straightforward, easily referenced list. It is a great plan to incorporate into your reading, either on a regular basis or at least semi-frequently. For example, you could do this twice a year or alternate between this plan in months consisting of 30 days the book of Proverbs in months with 31 days.
