If we continue with the 24th (and last) period in Keiti we find that in G we must jump to the glyphs immediately before the beginning of that calendar to find parallel glyphs. In a way we get a 33rd period, though 33 is an odd number and therefore a 33rd period cannot belong to the calendar proper:

Ga2-20	Ga2-21	Ga2-22	Ga2-23	Ga2-24	Ga2-25		Ga2-26
Eb6-9	Eb6-10	Eb6-11	Eb6-12	Eb6-13		Eb6-14

The expressions differ somewhat, but by utilizing more parallels (in other texts) it is obvious that the subject is, if not identical, yet describing similar events.

Furthermore, later in E there appear glyphs (Eb6-23--30) which resemble earlier glyphs in G (Ga1-17--25), but we leave those aside. They are not needed in order to compare the calendars.
