Already early when I tried to group the glyphs into manageable sequences I decided Ca4-26--29 should belong in the following sequence rather than be closely connected with the preceding glyphs - the mago pair in Ca4-28--29 is reflected in another similar such pair in glyph line Ga5:

Ca4-17	Ca4-18	Ca4-19

Ca4-20	Ca4-21	Ca4-22	Ca4-23	Ca4-24	Ca4-25

Ca4-26	Ca4-27	Ca4-28	Ca4-29
Ca5-1	Ca5-2	Ca5-3	Ca5-4
Ca5-5	Ca5-6	Ca5-7	Ca5-8

The last 4 glyphs in line Ca3 should be counted as the beginning of next line Ca4 and likewise Ca4-26--29 should belong to the following line Ca5.

With 'planetary colours' applied we can see that number 25 (a square of Saturn the fire maker) is equal to the black moonless night number 25 + 4 = 29:

Ca4-20	Ca4-21	Ca4-22	Ca4-23	Ca4-24	Ca4-25

Saturday comes before the day of the Sun King (26) and number 25 must belong to Saturn, but at the same time it must be the 29th day in the month because of the addition of 4 glyphs at the beginning.

Likewise number 26 can be understood as equal to the 30th day, a day which will alternate between being light and dark - the lunar month is 29½ nights long. Sun is present only during half the year too, alternating between being present and absent.
