I came across this brief work by Richard Baxter some time ago. Puritans are not know for their brevity (e.g. Thomas Watson’s All Things for Good, which is an exposition of one verse-Romans 8:28!), but this is a rather concise and helpful document.
Richard Baxter provides some very practical guidance “for spending the day in a holy manner.” You can access the article online here. I’ve also converted it to a two-page PDF for easier printing. I have personally found it to be useful.
