As to the intentions of the creators of Manuscript E we can guess they presumably wished to document - before it was completely forgotten - the established worldview as it had been prior to the arrival of the foreigners.

The ancient rongorongo tablets were no longer at hand, they had been burned or taken abroad. But, as Barthel has suggested, the creators of Manuscript E could have relied on the G text as it had been published in a book. And handwritten copies of parts of some of the old rongorongo texts might have been accessible too.

So it seems reasonable to assume that the date Hora nui 2 (E:74) given for the launching of the Royal Double Canoe had been chosen in order to establish the place for the time-frame of Bharani as coordinated from the time-frame of the Gregorian calendar.

Time had 'run out' (run down) for the old Julian calendar,

and the date for the 'birth' of the Gregorian calendar had been chosen as °October 15, which when 'translated' to the situation down on Easter Island (south of the equator) ought to correspond to "October 15 - because that would fix it to Rehua (Ashes, Antares).
