A. The 'moon' mauga (Eb5-11) can be used to mark the 15th full moon night, given that 7 glyphs are used for each night and the calendar starts with the last glyph in the 1st period, immediately beyond the 'dark' mauga (Eb2-13). In this perspective an allusion to the dark 29th night of the moon and the season of the 'dark' mauga seems irresistible.

B. The 'moon' mauga can also be used to count periods of 13 nights, given that the counting begins with the 1st glyph in the 2nd period. Eb5-11 will then be glyph number 104, i.e. be the last glyph in the 8th period, with 2 periods remaining to Eb6-2 (number 130).

C. The 'dark' mauga (Eb2-13) can be used to count through the winter season, provided it has 186 days, and given that the calendar begins with the 1st glyph of the 1st period. The 'dark' mauga will then have two ordinal numbers, not only the final 186 but also 19 (which is a number characterizing 'final' for the sun - cfr 29 as 'final' for the moon).

D. The 'light' mauga (Eb4-4) marks the end of the 1st half of 150 glyphs. Therefore it can be used to refer to full moon (the 15th night of the moon), given that each night is counted as 5 glyphs, and given that counting begins with the 1st glyph in the 1st period. It can also be used to mark the midpoint of summer, for instance by having 1 glyph for each day - allowing summer to stretch for 150 days. If each glyph is given 2 days, the calendar can be expanded to cover 300 days (or 10 months à 30 days).

E. On a more advanced level it can be shown that the 'moon' mauga divides the cycle of the calendar into 4 equal parts (with 42 glyphs in each) and that their sum (168) is a mirror image of the 186 glyphs of the 'dark' mauga. Summing up we get 168 + 186 = 354 = 12 * 29½ = 6 * 59 'moon double months'.
