In the 5th period of the E calendar spring equinox apparently is described. Then, maybe, follows (in period 6) an overview:

5
	Eb3-1	Eb3-2	Eb3-3	Eb3-4	Eb3-5	Eb3-6
	34	35	36	37	38	39
6				34 etc are ordinal numbers counted from the beginning of the calendar (Eb1-37).
	Eb3-7	Eb3-8	Eb3-9
	40	41	42
	Eb3-10	Eb3-11	Eb3-12	Eb3-13	Eb3-14	Eb3-15
	1	2	3	4	5	6
					Eb3-11 is probably located at the beginning of summer.
	Eb3-16	Eb3-17	Eb3-18	Eb3-19
	7	8	9	10
