The Eldar divided their solar year (or loa 'growth') into six seasons of unequal length. The lengths are unequal because the Quendi were more sensitive to and concerned with the transition of one season into another and the seasonal changes in vegetation as the wheel of the year turned.
(I did not include Mettarë because it is the day just before Yestarë, and thus is the equivalent of "New Year's Eve". It is important as a holiday, but not as a seasonal transition in itself.)
But how do we relate these dates to the solar year as we know it?
When does the loa start, and why?
According to Appendix 'D' of The Lord of the Rings,
(...) the loa began with 'yestarë', the day immediately before Tuilë (Spring) and ended with 'mettarë', the day immediately after Coirë (Stirring). Between Yavië and Quellë were inserted three enderi or 'middle-days'. This provided a year of 365 days which was supplemented by doubling the enderi (adding 3 days) in every twelfth year.
How any resulting inaccuracy was dealt with is uncertain. If the year was then of the same length as now, the yén (a period equaling 144 years) would have been more than a day too long. That there was an inaccuracy is shown by a note in the Calendars of the Red book to the effect that in the 'Reckoning of Rivendell' the last year of every third yén was shortened by three days: the doubling of the three enderi due in that year was omitted ; 'but that has not happened in our time'. Of the adjustment of any remaining inaccuracy there is no record.
But at exactly what point in the solar year did the loa begin?
This is a complex question. Let us look at the evidence:
So, how to solve this puzzle?
Shire April 6th (6 Astron) is equivalent to the beginning of the Elven year (loa); which corresponds to our March 28th. Taking into account fact #3 above, and applying the offset to the dates.
The question immediately arises: Why would the Quendi begin their solar year approximately a week after the vernal equinox, and not directly on the equinox itself? The explanation, I think, is that the loa was not strictly a rule based calendar, but neither was it precisely a lunisolar calendar, but something of a combination of both - with a strong stellar-calibration component. As we know, 'Summer' and 'Winter' each had 72 days, and the remaining seasons 54 each. It is significant that each of these numbers is evenly divisible by 6, as the Quendi used a six day 'week', which they called an enquië.
Additionally, we know (from linguistic evidence associated with the Lost Tales), that both the Summer and Winter solstices were celebrated. Given these facts, we now look for evidence that the Quendi used some sort of astronomical calibration for their calendar, much like the ancient builders of Stonehenge were said to do, or the ancient Mayans.
Whatever the astronomical event was, it must have been something fairly obvious that could be noted and acted upon by a population that was at least semi-nomadic (references to Elvish "wandering" - to say nothing of the Great Journey - are scattered throughout the whole Legendarium). This would seem to rule out large edifices such as Stonehenge or pyramidal constructions for the population as a whole, though it is certain that the Noldor, in particular, attained and surpassed such technology.
Using either of the solstices as a calibration point doesn't seem to fit; as each solstice would occur 5 enquier after the start (or 7 enquier before the end) of 'Summer' or 'Winter', respectively. This doesn't seem to make sense given the fact that both 'Summer' and 'Winter' contained 12 enquier, and thus are evenly divisible into two halves of 6 enquier each. And, since the seasons are of unequal length and none fall upon an equinoctial boundary, the equinoxes don't seem to be likely points either.
Surprisingly (and serendipitously) I discovered that the Pleiades, called the Remmirath ('Netted Stars') by the Elves, appears overhead (culminates) at midnight on November 21st – the beginning of Hrivë (Winter). In addition, they rise with the Sun at the beginning of Lairë (Summer), which admittedly cannot be seen directly - were it not for the fact that another constellation, which we know as Corona Borealis, culminates at midnight at the beginning of Lairë, as it lies exactly opposite the Pleiades in the sky.
Both of these events are explained more fully in the The Pawnee Star Calendar. Thus, using the date of November 21st on the Gregorian Calendar as a calibration date, and applying the length of the seasons forward and around from this date, we arrive at exactly the points determined by calculation using the Encyclopedia of Arda's calendar.
I should also mention here that the stellar configuration at the end of Varda's labours in Chapter 3 of the Silmarillion matches what is seen at midnight, November 21st.
"Of the Coming of the Elves" describes Varda's labours and the resulting sky:
Then Varda went forth from the council, and she looked out from the height of Taniquetil, and beheld the darkness of Middle-earth beneath the innumerable stars, faint and far. Then she began a great labour, greatest of all the works of the Valar since their coming into Arda. She took the silver dews from the vats of Telperion, and therewith she made new stars and brighter against the coming of the Firstborn; wherefore she whose name out of the deeps of time and the labours of Eä was Tintallë, the Kindler, was called after by the Elves Elentári, Queen of the Stars. Carnil [Mars] and Luinil [Vega*], Nénar [Capella*] and Lumbar [Saturn], Alcarinquë [Jupiter] and Elemmírë [Mercury] she wrought in that time, and many other of the ancient stars she gathered together and set as signs in the heavens of Arda: Wilwarin [Cassiopeia], Telumendil [Gemini?], Soronúmë [Lyra*], and Anarríma [Leo*]; and Menelmacar [Orion] with his shining belt, that forebodes the Last Battle that shall be at the end of days. And high in the north as a challenge to Melkor she set the crown of seven mighty stars to swing, Valacirca, the Sickle of the Valar and sign of doom [Ursa Major/The Big Dipper].
It is told that even as Varda ended her labours, and they were long, when first Menelmacar [Orion] strode up the sky and the blue fire of Helluin [Sirius] flickered in the mists above the borders of the world, in that hour the Children of the Earth awoke, the Firstborn of Ilúvatar. By the starlit mere of Cuiviénen, Water of Awakening, they rose from the sleep of Ilúvatar; and while they dwelt yet silent by Cuiviénen their eyes beheld first of all things the stars of heaven. Therefore they have ever loved the starlight, and have revered Varda Elentári above all the Valar.
