On side a the number of glyphs (392) - 16 = 376, but by counting also the position of day zero the number becomes 377 (i.e. 378 as in the circuit of Saturn - 1):

... The ordinary year in the previous Roman calendar consisted of 12 months, for a total of 355 days. In addition, a 27-day intercalary month, the Mensis Intercalaris, was sometimes inserted between February and March. This intercalary month was formed by inserting 22 days after the first 23 or 24 days of February; the last five days of February, which counted down toward the start of March, became the last five days of Intercalaris. The net effect was to add 22 or 23 days to the year, forming an intercalary year of 377 or 378 days ...

Immediately beyond day number 36 (= 401 = 365 + 36 = 377 + 24), when in 5 February Hun-Nal-Ye had entered the scene,

... the Palenque scribes repeated Creation again and described it as 'it was made visible, the image at Lying-down-Sky, the First-Three-Stone-Place'. Then we learned that five hundred and forty-two days later (1.9.2 in the Maya system), Hun-Nal-Ye 'entered or became the sky' (och ta chan). This 'entering' event occurred on February 5, 3112 BC ...

a place with 3 'stone heaps' (pyramids) began in June 11 (162), i.e. in the first day of the month of Jus Piter (Father Light).

... One of the youths said to Ira, 'Why do we want heaps of stone?' Ira replied, 'So that we can all ask the stones to do something.' They took (the material) for the stone heaps (pipi horeko) and piled up six heaps of stone at the outer edge of the cave. Then they all said to the stone heaps, 'Whenever he calls, whenever he calls for us, let your voices rush (to him) instead of the six (of us) (i.e., the six stone heaps are supposed to be substitutes for the youths). They all drew back to profit (from the deception) (? ki honui) and listened. A short while later, Kuukuu called. As soon as he had asked, 'Where are you?' the voices of the stone heaps replied, 'Here we are!' All (the youths) said, 'Hey, you! That was well done!' ...

162 (June 11) - 84 (Julian equinox) = 78 = 1/10 * 780 (circuit of Mars). The Gregorian equinox came 4 days too early compared to the Julian equinox and 80 (March 21, 0h) + 78 (= 3 * 26) = 158 (June 7), where according to Metoro the rare and precious Toromiro tree of Easter Island once upon a time had thrived down in the waters (kua noho te vai) of Rano Kau.

This had been in APRIL 4 (10 days after the Julian equinx in MARCH 25) and 64 right ascension days of precession earlier than the time of rongorongo, i.e. around 64 * 71 = 4544 years ago, or around 2700 BC when the 3 great 'stone heaps' on the Giza Plateau had been built on the west bank of the Nile.

The circuit of Mars was 402 (= 780 - 378) days longer than the circuit of Saturn (the great time giver),

and the empty hand outstretched in front in Cb10-9 could have illustrated this fact, because 6 February was day 365 + 31 (January) + 6 = 402, and a new circuit of Mars would then begin, which seems to be affirmed by the drawing of a 'sun fist' in Cb10-10:

... The practice of turning down the fingers, contrary to our practice, deserves notice, as perhaps explaining why sometimes savages are reported to be unable to count above four. The European holds up one finger, which he counts, the native counts those that are down and says 'four'. Two fingers held up, the native counting those that are down, calls 'three'; and so on until the white man, holding up five fingers, gives the native none turned down to count. The native is nunplussed, and the enquirer reports that savages can not count above four ...

In day 4 after 5 February, according to the crooked Gregorian calendar 'canoe' which had omitted to adjust for the precession from the time of Caesar to the Council of Nicaea,

... Taetagaloa [Not-Tagaroa] goes right over there and steps forward to the stern of the canoe saying - his words are these: 'The canoe is crooked.' (kalo ki ama). Instantly Likāvaka is enraged at the words of the child. Likāvaka says: 'Who the hell are you to come and tell me that the canoe is crooked?' Taetagaloa replies: 'Come and stand over here and see that the canoe is crooked.' Likāvaka goes over and stands right at the place Taetagaloa told him to at the stern of the canoe. Looking forward, Taetagaloa is right, the canoe is crooked. He slices through all the lashings of the canoe to straighten the timbers. He realigns the timbers. First he must again position the supports, then place the timbers correctly in them, but Kuikava the son of Likāvaka goes over and stands upon one support. His father Likāvaka rushes right over and strikes his son Kuikava with his adze. Thus Kuikava dies. Taetagaloa goes over at once and brings the son of Likāvaka, Kuikava, back to life. Then he again aligns the supports correctly and helps Likāvaka in building the canoe. Working working it is finished ...

... When Julius Caesar established his calendar in 45 BC he set March 25 (3-25) as the spring equinox. Since a Julian year (365.25 days) is slightly longer than an actual year the calendar drifted with respect to the equinox, such that the equinox was occurring on about 21 March in AD 300 and by AD 1500 it had reached 11 March. This drift induced Pope Gregory XIII to create a modern Gregorian calendar. The Pope wanted to restore the edicts concerning the date of Easter of the Council of Nicaea of AD 325 ...

the Chorti diviners began to look for 5 proper stones in order to build their new quincunx map of the year, in form like a pyramid.

Midsummer is the flowering season of the oak, which is the tree of endurance and triumph, and like the ash is said to 'court the lightning flash'. Its roots are believed to extend as deep underground as its branches rise in the air - Virgil mentions this - which makes it emblematic of a god whose law runs both in Heaven and in the Underworld ... The month, which takes its name from Juppiter the oak-god, begins on June 10th and ends of July 7th. Midway comes St. John's Day, June 24th, the day on which the oak-king was sacrificially burned alive. The Celtic year was divided into two halves with the second half beginning in July, apparently after a seven-day wake, or funeral feast, in the oak-king's honour ...

... On February 9 the Chorti Ah K'in, 'diviners', begin the agricultural year. Both the 260-day cycle and the solar year are used in setting dates for religious and agricultural ceremonies, especially when those rituals fall at the same time in both calendars. The ceremony begins when the diviners go to a sacred spring where they choose five stones with the proper shape and color. These stones will mark the five positions of the sacred cosmogram created by the ritual. When the stones are brought back to the ceremonial house, two diviners start the ritual by placing the stones on a table in a careful pattern that reproduces the schematic of the universe. At the same time, helpers under the table replace last year's diagram with the new one. They believe that by placing the cosmic diagram under the base of God at the center of the world they demonstrate that God dominates the universe. The priests place the stones in a very particular order. First the stone that corresponds to the sun in the eastern, sunrise position of summer solstice is set down; then the stone corresponding to the western, sunset position of the same solstice. This is followed by stones representing the western, sunset position of the winter solstice, then its eastern, sunrise position. Together these four stones form a square. They sit at the four corners of the square just as we saw in the Creation story from the Classic period and in the Popol Vuh. Finally, the center stone is placed to form the ancient five-point sign modern researchers called the quincunx ...
The foundation of Rome was around 2600 years before the time of rongorongo.
"Seamen have called it [Mintaka] the Golden Yard-arm; tradesmen, the L, or Ell, the Ell and Yard, the Yard-stick, and the Yard-wand, as occupying 3° between the outer stars, - the Elwand of Gavin Douglas; Catholics, Our Lady's Wand; and the husbandmen of France and along the Rhine, Râteau, the Rake. In upper Germany it has been the Three Mowers; and it is often the Magi, the Three Kings, the Three Marys, or simply the Three Stars ..." (Allen) ... 'Tell us a story!' said the March Hare. 'Yes, please do!' pleaded Alice. 'And be quick about it', added the Hatter, 'or you'll be asleep again before it's done.' 'Once upon a time there were three little sisters', the Dormouse began in a great hurry: 'and their names were Elsie, Lacie, and Tillie; and they lived at the bottom of a well — '

Day 14 counted from the place of the pyramid of Khufu (corresponding to June 11) the Full Moon was at λ Sagittarii ('Lacie') which was half a year away from June 25 = the day after Father Light (the Oak, Jupiter) had been burnt alive.

However, it seems as if the Mayas had chosen July 11 at Cancer instead of Gemini and June 11 a month earlier, because their drawing in form like λ was at Cancer and at Gemini the form was like that of henua (Land). Darkness (death) could only appear after light (life) had arrived.

Egyptian menchet		Phoenician lamedh		Greek lambda	Λ (λ)
... Wikipedia has no information regarding the origin of the Phoenician lamedh, but the Egyptian 'cloth' hieroglyph (menchet) is - I suggest - related to the 4 upside down sky pillars. I.e. the basic element of the 'covering' hieroglyph could have indicated darkness:

... Men's spirits were thought to dwell in the Milky Way between incarnations. This conception has been handed down as an Orphic and Pythagorean tradition fitting into the frame of the migration of the soul. Macrobius, who has provided the broadest report on the matter, has it that souls ascend by way of Capricorn, and then, in order to be reborn, descend again through the 'Gate of Cancer'. Macrobius talks of signs; the constellations rising at the solstices in his time (and still in ours) were Gemini and Sagittarius: the 'Gate of Cancer' means Gemini ...

16 days beyond June 11 (and Khufu) was day 161 + 16 = 177 (= 6 * 29½), when the Full Moon was at day 360 (December 26):

	... The leap day was introduced as part of the Julian reform. The day following the Terminalia (February 23) was doubled, forming the 'bis sextum - literally 'double sixth', since February 24 was 'the sixth day before the Kalends of March' using Roman inclusive counting (March 1 was the 'first day'). Although exceptions exist, the first day of the bis sextum (February 24) was usually regarded as the intercalated or 'bissextile' day since the third century. February 29 came to be regarded as the leap day when the Roman system of numbering days was replaced by sequential numbering in the late Middle Ages ...
