To me this article is missing something quite important, that is the affect of the cycle on moon phases: that the moon returns to the same celestial longitude and same lunar phase on the same calendar date every 19 years. 69.121.188.60 ( talk) —Preceding undated comment added 02:56, 13 June 2016 (UTC)
What is this Greek thing all about? Wikipedia's other articles state that Odysseus returned after 20 years, which is longer, not "at the exact moment when one Metonic cycle has passed." I think some clarification is in order. 70.20.169.235 ( talk) 03:40, 21 February 2008 (UTC)

I found the paper: [1], and variation [2] at the author's website. There's no publishing date, no references in the paper. On a quick look I have no clear reason to believe it is more than the author's unproved speculation. Tom Ruen ( talk) 19:07, 3 July 2009 (UTC)
I'm aware that WP guidelines are to place the words in bold as early in the sentence as possible. However, the guideline does not say the bold words must be first. Nor does it say 'you must contort the normal word order of English syntax in order to place the bold words first' nor 'the bold words must come first even if it makes the sentence harder to understand or read.' I'm also aware that there are editors who prowl articles in order to make just these kinds of changes. There are probably better uses of time.
In my view, this article is an example of how readers can be served by a phrase orienting them to the context of the topic before dropping the bold words. Cynwolfe ( talk) 16:48, 5 July 2010 (UTC)
What, a year isn't a cycle?? — Tamfang ( talk) 18:57, 14 December 2010 (UTC)
I disagree. It correlates with BOTH 19 tropical years AND 235 synodic months and so 254 lunar orbits. That is what makes it notable. The lunar orbit is less significant than the synodic month. Karl ( talk) 11:26, 15 December 2010 (UTC)
p.s. I also added "255 draconic months (lunar perigees nodes) = 6939.1161 days" since this match is what makes it an
eclipse cycle, repeating for 4-5 eclipse events.

There is a definite connection between the 29.5 day lunar/synodic month, 355 day lunar year, 365.25 solar/tropical year, the Julian/Gregorian Calendar, and "7_4". The ancient Egyptians (and eventually others) practiced sacred geometry with its primary premise of "As above, so below". They observed (with the naked eye) that there are 7 moving objects in the heavens ("7 heavens") and 4 of these do NOT cast shadows on Earth (Venus does). They observed the lunar monthly cycle of 29 1/2 days as 4 phases of roughly 7 days each (~7.4 days). The Moon thus gives us the 7-day-week and the 4-week 'moonth'. The ancients observed that the 12-month lunar year (354 day) + a 7-day-week + 4 days = solar/tropical year. (7.4 x 4 = 29.6 x 12 = 355.2 + 7 + 4 = 366.2 leap year).
The Roman and Egyptian astrology (astronomy) advisors to Roman Emperor Julius Caesar brought this "Combination of 7 & 4 from the gods" to his attention. He then decreed that the Roman Calendar be adjusted to 365 days by having 7 31-day-months + 4 30-day months + February's 7-day weeks x 4 weeks + the 'leap day' every 4 years.
Sometime after Kepler & Galileo, the mean distance from the Sun of the inner planets were calculated at Venus .7 AU & Mercury .4. Besides Earth, in this solar system there are 7 planets and 4 Trans-Neptunian Plutoids.

It's not immediately clear from the article if there is any precise definition of the cycle. So it's not clear how long the cycle is. Candidates provided include:
Perhaps there are several cycles, of nearly the same length, each called the Metonic cycle. Whatever the case, compare the Wikipedia article to entries found at dictionary.reference.com:
I'll give this article a few weeks for someone with better knowledge of the subject to fix it. If it's not clarified during that time, then I'll change the first paragraph so that the cycle is 235 synodic months by definition, as claimed already in the 2nd section, and add relevant citations to the reference section. 66.99.2.214 ( talk) 19:13, 30 December 2014 (UTC)

The citations are a mess. I looked for the earliest version that had any citations, and I did not recognize the citation style, so I would not be able to create new citations that conform to that "style". Is there any objection to using Citation Style 1? Jc3s5h ( talk) 14:47, 8 March 2022 (UTC)
I see you are in mid-edit so I won't interrupt. The McCarthy & Breen formatting is poor: I suggest replacing it with this, which matches the cover:

nothing, unless one side is about lunations and the other somehow about the solar year. Here, the article is simply saying that the lunations are the lunations, which is trivial/meaningless. — LlywelynII 18:28, 12 August 2023 (UTC)
