E.g. today there was an eclipse of the sun, which peaked at 9:20am from my location, which intuitively must be the new moon since the moon face is never less illuminated than when the sun is directly behind it, but the official "new moon" time was 10:55am, because that was when the moon was directly between the sun and earth from the perspective of the ecliptic plane. It seems like this distinction should be made in this article, and I would add a section but I don't feel qualified to do so. Any takers?

Before applying such a full-on mark of condemnation to an article, I would expect to see a talk page topic that makes the case that the whole article is a hopeless case, completely incomprehensible, beyond repair. I see no such case. If the state of the article is anything less than that severe, then

I take your point about it being obtrusive (but you should try stumbling around and finding a huge block like it in the notes section, when you can't see well) for a relatively small problem: So just remove that and nothing else. Only revert as a last resort, especially if you're not willing to look

I think the moon is exactly half when the earth and sun are 90° apart from the moon, not when moon and sun are 90° apart from the earth. And the reason is that for the moon to be exactly half, the sun would have to be shining directly on the edge of the visible part of the moon, meaning that the sun

IMO, the effect of that note at the top of the article is to assert that the whole article is confusing. That, at least to me, seems a significant overreaction, because it is not a reasonable assessment of the article as a whole. (I accept to call it "extreme" was, well, extreme and I withdraw that

I was recently educated re: the distinction between "lunar phase" as commonly understood: the percentage illumination of the lunar disc, and as it is apparently considered in astronomical context: defined by the alignment of the sun/moon/earth system as viewed from the perspective of the ecliptic.
1030:, from January 2006, uses the mdy format. The earliest version I found that has citations with dates uses a style that is no longer accepted, yyyy-mm-dd for publication dates. I suggest the format for dates outside citations be restored to mdy, and the mdy format be used within citations as well. 507:
The official and traditional astronomical definition is given in the first footnote. Why would you want to define the lunar phases as seen from the Moon as most people actually live on the Earth? I agree that the article should clearly distinguish between the quarter phases and dichotomy.

When I saw mention of lunar phases and the Gregorian calendar, I thought of the aspects of the Gregorian calendar that are used to calculate the date of Easter. But that is exhaustively covered in other articles, and I don't think it needs to be mentioned

I came to this page hoping to find some imformation about early theories to explain the phenomenon. I do not know why this is completely omitted. Anyone knowledgable in the subject, please create a section, hopefully it will be expanded overtime.

I have deleted the section about lunar and calendar month coincidences. Consensus is that it had no value. I have added a brief section on use of lunar phases for "timekeeping" (long-range time, as in "four moons ago" rather than "four minutes
