How it reads days
Full names, three-letter abbreviations and short forms like Tu and Th all work, in any capitalization, anywhere in the line. The week starts on Monday and ends on Sunday. Lines on the same day keep their original order; lines with no day move to the top.
Very short lines can be ambiguous, because a lone “M” or “F” could be part of another word. If something lands in the wrong place, spell the day out or use the three-letter form.
