I have listed also the dates because they could be important in order to understand the text:
Rogo in Ca10-29 is probably representing Gregorian day 364. Metoro said te tagata which could be his way to state that the regular solar year is 'fully grown' (completed) with day 364 (= 4 * 91 = 13 * 28). To reach day 364 at December 30 is to count from January 1. In a way December 31 is a day 'zero', which necessitates the expression 'a year and a day' to describe 365 days. The text is evidently beginning with March 22 (81) and 80 + 285 = 365. By counting March 21 as right ascension day 0 December 30 will be RA day 284. The Gregorian day numbers can be reached by adding 80 to the glyph (RA day) numbers . One of the most obvious Signs in the text is the beginning of the Moon calendar with glyph 157 in Gregorian day 80 + 157 = 237:
The measure used is here 29½ nights per month and 237 = 8 * 29½ + 1. But the Sun measure could have been 30 days because there is a dot in front in Ca6-20, where 240 = 8 * 30. Furthermore, 8 * 29 = 232 (= 236 - 8 * ½):
We should therefore be aware of the following number values:
