So, the quote which Geekritique references in the video is slightly out of context. Diab very specifically said that they had a year in mind and then abandoned that idea, and we don't know when in the development process that happened (it could have been long before filming began). It's why I'm hesitant to use the moon and rely on what they used to want. However, I see that most people are in agreement with June 2024, so we'll go with that unless people are changing their mind after knowing the context.
Yeah, if the idea of the Mohamed Diab quote is to imply that they thought about matching the moon to the date perfectly... I doubt it, to be honest. The idea is just that the show begins with a new moon and progresses to a full moon through the show. And the show happens to start on a Thursday, then get to a Monday, etc.. They had a sense of the timeline sure, but I doubt they had exact very very specific dates laid out so much as just "Spring 2024" or "Spring 2025" to be honest. I don't see much reason to believe otherwise.
To me, the exhibit dates (and potentially the banners line in relation to it), the Disney+ timeline, and the moon's phases are the key points. And maybe that quote about the Blip, it's a factor at least. And the Cairo sunset implies a certain time of year, and since the question here is April 2025 vs. June 2024, that indirectly is a factor towards the year, since the times of year differ depending on the year choice.
If you're really putting emphasis on the moon's phases being perfect, you go with 2024. This also aligns better with that Blip quote, though it definitely does not seem particularly considered. But I think the emphasis on the points for 2024 regarding the moons has got carried away with assumptions. There's one piece there: the moons and the days of the week align very nicely with June 2024.
But the moon's phases are only 2 days off with April 2025, and then you have the banners line fitting extremely nicely, the spring appearance, the fact it's much closer to fitting it being dark at 6 o'clock in Cairo, and you fit the Disney+ timeline. And I think after Multiverse of Madness, the Marvel promotion and articles, etc. as mentioned, it's getting more important to align with the Disney+ timeline where possible (while still shunning it when not, of course). The Disney+ timeline has also never had anything more than one or two slots off from where it should be, and this would be three, a record for how wrong it could be. Actually, not even - it would be four, it's just that No Way Home isn't on Disney+ anywhere, but it's obvious it goes between Far from Home and Multiverse of Madness, it's just essentially "invisible". We're treating the Disney+ timeline here as "If it aligns, great, if it doesn't, don't care"... like it or not, it's a big piece of evidence. It's just with other incorrect Phase Four placements, it's got weight 5 and a total of weight 100 puts the projects elsewhere, so they win out. Here, it's got weight 5 and the other evidence is of similar magnitude, it just feels a lot more powerful because it's all we have. But it means the Disney+ timeline does have more relative sway with this show, given the lack of evidence.
With only slightly more evidence outside of the Disney+ timeline for 2024 than the evidence also there for 2025, and then you throw the Disney+ timeline into the mix which is important if far from infallible (plus some smaller bonuses: the fact that the Blip is not at all referenced in the slightest - this is more in keeping with the 2025 projects we've seen than the 2024 projects, it's not treated as recent; the fact that the MCU has been generally progressing its timeline broadly speaking since November 2021 and this would be an uncharacteristic big step back in the timeline if 2024)... I feel that while it would be nice to have the moon fit really comfortably and use 2024, it's just not quite realistic to go with that and puts too much faith in assumption that this was artist intention, when the signal from Marvel is it's Spring 2025, and evidence does support this, and the moon is only very slightly off.
I think June 2024 is a nice and interesting and somewhat tempting proposition, but mostly based on wanting something to fit the real world perfectly in a way Marvel have not shown care to make fit before. There have been times we've ignored the moon, e.g. Iron Man, because "It doesn't fit, whatever" - it's a secondary source that if there were more evidence for the show's placement, would be disregarded pretty quickly, and is more meant to be deferred to after we have the time frame, when there's nothing else for a specific date and it might as well match up (e.g. Endgame, No Way Home), so I struggle with it coming first and placing the whole show year-wise based basically only on this very-likely-coincidental alignment of one moon matching one day (well, one two-day set of the moon), which is ultimately all this is (I'm not so sure about all the discussion around it being relevant). As mentioned, it feels the weight that gets is because of the lack of information generally. Taking the evidence the show and Marvel has actually given us otherwise... I still vote April-May 2025. That's what feels right to me, with the most total evidence.
