The implications of the hard work done so far on the beginning of side a of Tahua are potentially crucial and we must therefore investigate if day 1 and day 369 (= 177 + 192), according to the proposed calendar, really are represented by affirming glyphs:

		67
Ab8-84	Aa1-1		Aa1-69	Aa1-70	Aa1-71	Aa1-72
108 = 3 * 36	109		177 = 3 * 59	178	179	180 = 3 * 60

108 has zero in the center, 180 has it in front. 8 * 84 = 672 and at day 180 there is 172 (1-72), the difference is 500.

Glyph number 1 according to this imagined calendar will be Ab7-61. There are 84 glyphs also in line b7, and 84 - 60 = 24:

	22			82
Ab7-61		Ab7-84	Ab8-1		Ab8-84
1		24	25		108 = 3 * 36

Glyph number 177 + 192 = 369 will be Aa4-10 (because 108 + 261 = 369):

Aa4-7	Aa4-8	Aa4-9	Aa4-10 (261)	Aa4-11
366	367	368	369	370

261 = 761 (as in Ab7-61) - 500. If we take away 'fire' (rima, 5) only darkness will remain. 261 is 'one more' than 260 (= 13 * 20). 261 is also equal to the famous 9 * 29. And, we should notice that 9 * 19 = 171 (cfr Aa1-71). 261 is a Moon measure, 171 a Sun measure.

The pair in Aa4-10 resembles the pair in Aa6-45, 200 glyphs later:
