Lets count the glyphs on side a again. If we should exclude the last pair (at Alrisha / Thuban respectively at Hamal) - because they could have been needed in order to begin a cycle of 350 days - there will remain a pleasing 740 - 350 = 390 days = 30 * 13 (= 15 * 26). The Mayas used 13-day cycles and the Arabs preferred their manazil to have 13 days, we remember:

October 15 (2 * 144) was evidently a date of importance, to be compared with ºOctober 15 (288):

... The Julian calendar day Thursday, 4 October 1582 was followed by the first day of the Gregorian calendar, Friday, 15 October 1582 (the cycle of weekdays was not affected) ...

13 * 28 = 364 and 13 * 27 = 351. From te heke (the rafter) in Ca2-1 (27) to te vero in *Ca14-15 (378) there were 351 glyphs:

And once upon a time Anunitum (with Regulus culminating at midnight) had been at the beginning among the ecliptic constellations:

148 (May 28) - 96 (April 6) = 52 = 4 * 13 = 364 / 7.

If the regular year was counted as 52 weeks, then it would have been natural to regard the last 2 glyphs on side as outside the regular year:
