Line Ca5 is beginning with glyphs corresponding to July. However the first 4 days of July are at the end of line Ca4:
Perhaps this alludes to the difference between March 25 and March 21. The Julian calendar had spring equinox at March 25 and if counted from there Sirius would have risen - in rongorongo times - in day 181 - 4 = 177 or 3 synodic lunar double-months later. We can compare with the manzil Al Tuwaibe' - ruled by Aldebaran - which is beginning on June 26 = Gregorian day 177. 14 * 29½ = 413 equals the day number for Al Tuwaibe' 8, counted from the beginning of the previous manzil year; 48 + 365 = 413. This date corresponds to Gregorian day 184 and to day 180 if counted from March 25. Line Ca5 has 35 glyphs, although the last 4 of them probably are to be considered together with those at the beginning of line Ca6:
