1. Given that the left part of this glyph is to be regarded as a 'counter of times', then we can read: 'five times'.
2. The right part of this glyph has a sign with three upward-turned wedge-shapes on top of each other. This I think (and also Barthel as I can remember) shows 'darkness', i.e. I read: 'five times in darkness' or something like that.
3. One way is to count 30 * 12 = 360 and find that 5 nights are missing. These 5 nights could then be regarded as outside the sacred year (like the Egyptians of old did).
4. Another possibility - which I believe more probable - is to count 31 * 12 = 372, which gives 7 nights too many. We can reduce this difference by 5 and reach 367. In row nos. 1 and 3 we can then find the 2 missing 'dark nights'. They can be seen as 'fishes in the dark':
