It is necessary to keep in mind that down on Easter Island the stars in the night were the same as those north of the equator (although the stars located high up in the north were hard to see because they never went high above the horizon). Therefore, to use the Julian calendar in order to correlate dates with stars was in principle no problem. But they had to adapt to such facts as that Christmas was not in winter but in summer - like those of us who nowadays are living in Australia. The seasons were upside down, which could be seen from the orientations of the constellations and from the face of the Moon - where her C form did not indicate the waning phase as in the north but her growing phase.

... One detail which is iconographically of interest is whether the god responsible for separating Earth and Sky did so by raising the Sky with his upraised arms and hands, as in Tahiti and elsewhere, or with his feet as in New Zealand ...

By counting a month backwards from the Star-striking Falcon, Shahin tara zed (*272) at 'December 18, we will come to 'November 18 (*242) - and 242 (= 2 * 121) seems to have been a Significant number because this had been chosen as the number of glyphs on side b of the tablet.

I have here above assumed the date given for Hua tapu in the 12th month Welehu - and indirectly also for the date at the beginning of the circuit of Lono - was not according to the Gregorian calendar but according to the Julian calendar as applied to the stars in Roman times.

... The correspondence between the winter solstice and the kali'i rite of the Makahiki is arrived at as follows: ideally, the second ceremony of 'breaking the coconut', when the priests assemble at the temple to spot the rising of the Pleiades, coincides with the full moon (Hua tapu) of the twelfth lunar month (Welehu). In the latter eighteenth century, the Pleiades appear at sunset on 18 November. Ten days later (28 November), the Lono effigy sets off on its circuit, which lasts twenty-three days, thus bringing the god back for the climactic battle with the king on 21 December, the solstice (= Hawaiian 16 Makali'i). The correspondence is 'ideal' and only rarely achieved, since it depends on the coincidence of the full moon and the crepuscular rising of the Pleiades ...

In order to find the corresponding Gregorian dates we first have to add 1 day due to the precession from late in AD 1778 (when Captain Cook was playing Lono) to the time of rongorongo (fixed by me as AD 1842 in order to be in harmony with the relevant Arab star stations).

Then we possibly should adjust the date for the return of the Pleiades to visibility with 16 days in the other direction in order to find the corresponding true heliacal day. 18 November + 1 - 16 = November 3 (a π day). On Easter Island they did not look for the Pleiades in the evenings but in the mornings.
