I have found what I believe could be a calendar for the week in the Keiti text too. This calendar is not similar to the one we have seen earlier (in Large Santiago and in Large St Petersburg). And it has fewer glyphs, only 20 (in contrast to 42 in Large Santiago and 34 in Large St Petersburg). The pattern for the number of glyphs in this Keiti-calendar seems to be::

 

1st half of the week Number of glyphs Sum
Sunday 2 2
Monday 3 5
Tuesday 3 8
Wednesday 2 10
2nd half of the week Number of glyphs Sum
Thursday 2 2
Friday 4 6
Saturday 4 10

As could be expected these 20 glyphs are distributed with one half in the period Sunday - Wednesday and one in the period Thursday - Saturday. Quite as in the two earlier calendars of the week.
