In the 22nd period, at the other end of the calendar (though still at the end of the old year), we have a real ('living') ragi:

22
	Eb5-21	Eb5-22	Eb5-23	Eb5-24
23
	Eb5-25	Eb5-26	Eb5-27	Eb5-28

These two periods have identical 'end-of-period' glyphs (Eb5-24 and Eb5-28) showing that the periods belong together. The 23rd period connects to the last periods in the G and K calendars for the year, presumably indicating the darkest time of the year.
