2. On the other hand, we could say the important part of Ursa Major is beginning with Dubhe, the first of its 7 great stars - or 8 if we count also Alcor - constituting the familiar asterism we all know as the Big Dipper.

"Alcor is the naked-eye companion of Mizar, and, inconspicious though it be, has been famous in astronomical folk-lore." (Allen)

In the G text Dubhe coincides with glyph 104:

Ga4-20 (104) Ga4-21 Ga4-22 (*170) Ga4-23 Ga4-24 (108)
Dubhe (167.7)    Al Sharas (169.7), Zosma (170.2), Coxa (170.4)   Alula (171.5), Labrum (171.6)
September 5 (248) 6 7 8 9
Ga4-25 Ga4-26 Ga4-27 Ga5-1 Ga5-2 (*177) Ga5-3 (114)
λ Crateris (172.6), ε Crateris (172.9), γ Crateris (173.0) κ Crateris (173.5)  ξ Hydrae (175.3) θ Crateris (176.0), ω Virginis (176.3) ι Crateris (176.5), ο Hydrae (177.1)  ζ Crateris, ξ Virginis (178.0), λ Muscae (178.1), ν Virginis (178.2)
September 10 11 12 13 (256) 14 15

From κ Crateris (Ga4-26) to Benetnash (Ga6-5) the distance is exactly 36 days:

61 59
Gb6-25 Gb6-26 (*1) Gb6-27 Gb6-28 (411) 120
 0h (408.0)   Caph, Sirrah (409.5) Algenib Pegasi (410.8) 121.5
March 21 22 23 24 (83) 120
49 35
Ga2-29 (60) Ga4-26 (110) Ga6-5 (146)
Tegmine (124.3)  49.2 κ Crateris (173.5) 36.0 Benetnash (209.5)
July 23 (204) 49 September 11 (254) 35 October 17 (290)

84 - 36 = 48.

There are also 84 days from Dubhe to what could be the end of the year:

80
Ga4-20 (104) Ga7-15 (185) Ga7-16 Ga7-17
September 5 (248) 80 November 25 26 27 (331)
84
Ga7-18 Ga7-19 Ga7-20
November 28 (332) 29 30

There could follow a dark month (December), outside the regular calendar. On Hawaii they counted 33 nights from the evening return of the Pleiades to winter solstice. There are 33 nights from November 18 to December 21, but south of the equator they ought to have counted 35 nights from November 16 (cfr The Structure of the G Text):

Ga7-5 Ga7-6 (*240) Ga7-7 Ga7-8 Ga7-9 Ga7-10 (180)
November 15 16 (320) 17 18 19 20
Ga7-11 Ga7-12 Ga7-13 Ga7-14 (**156)
21 22 23 24

I guess the creator of the G text used number 33 because he evidently used both the star map and the calendar from north of the equator. If so, then we can see why November 27 ought to be associated with the final of the regular year:

Ga7-15 (185) Ga7-16 Ga7-17
November 25 Antares (330) 27
173
Ga7-18 Ga7-19 Ga7-20 (190) Gb5-10 Gb5-11 Gb5-12
November 28 (332) 29 30 364 365 366
177 (= 6 * 29½)

Perhaps the creator of the text thought our calendar ended with 'a year and a day'.

November 27 would then have forced other important dates to be pushed towards the 27th in a month, e.g. July 27 (208).
