Avengers: Endgame - forcefully has to take place in October 2023; its 9 years after 2014, 5 years after 2018, 8 months before June (FFH)
WandaVision - forcefully November 2023 according to a calendar that shows up in the show and being set a few weeks after Endgame
Shang-Chi - set in April, before She-Hulk and MoM (which in turn is before Hawkeye, according to the timeline book and Disney+, which is solidly in December 2024), making it April 2024
Falcon and Winter Soldier - set in April-May (between Shang-Chi and FFH, according to the timeline book) with the final events being set mostly shortly after the final events of FFH (according to timeline book)
Spider-Man: Far From Home - starts in late June and covers the beginning of July, starts 8 months after Endgame (which is 2023), so its in 2024
Eternals - set in the fall, between FFH and NWH (timeline book), so fall 2024; Ajax 5 years line has to be ignored (the Snap would have actually happened six years before the events of the film)
Spider-Man: No Way Home - set before Christmas and shortly after Halloween, set after FFH and before Hawkeye (the Rockefeller Christmas tree is still up), so it has to be November 2024 (final scene set in early December)
Doctor Strange in the Multiverse of Madness - set after NWH and before Hawkeye (timeline book and Disney+), and before snow starts to fall in NYC, putting it in November 2024
Hawkeye - several evidence in and off screen that it is in December 2024
MoonKnight - early 2025 (after Hawkeye, according to timeline book and D+), the egyptian exposition in London opens in March and ends in June (iirc); set before BP:WF (according to timeline book and D+), which is set during school months (ends in late May), and is set before She-Hulk (according to timeline book and D+) which has an August setting for the gala in the second last episode)
Black Panther: Wakanda Forever - May 2025, after MoonKnight and before She-Hulk (according to timeline book and D+), before the end of MIT classes
She-Hulk - covers many months, but the midpoint of the show's events are solidly set after BP:WF (timeline book and D+), and with an August setting for the gala in the second last episode; also set before Ms.Marvel (according to timeline book and D+), so its set in mid 2025
Ms.Marvel - according to timeline book and D+, placed after She-Hulk and before GotG Holiday special, which is set in late December, so in the final half of 2025; several circumstancial evidences put it in September 2025, mostly
Thor: Love and Thunder - set after Ms.Marvel and solidly before GotG HS (according to timeline book and D+), must be as early as possible due to Groot's appearance being much closer to that of his Endgame's form than the one from GotG HS, so ideally October 2025 (the earliest it can be). Jane's letter would have to be written around early 2017, which sort of kind of works, but its not really ideal. Groot would have to somehow change his physique a whole lot in just two months. This also contradicts Gunn's declaration that Thor and the Guardians were only together for like a few weeks or something, but who knows really if they really were together all the time, in the two years that span between Endgame and LaT. Maybe he just occasionally tagged along with the Guardians, as Thor completed his spiritual journey (would also make sense how the Guardians don't seem really very attached to Thor either).
Werewolf by Night - set after Love and Thunder and before GotG HS (timeline book and D+), explicitly said in the book to be set in Halloween, solidifying an October placement for LaT.
Guardians of the Galaxy Holiday Special - set in Christmas 2025; pretty sure its explicitly stated to be set in 2025, in the timeline book, so there is no way to possibly push it to 2026 to make up for Groot's sudden growth since LaT (pushing the HS to 2026 would also put The Marvels two years after Ms.Marvel, which would be inconvenient, as Kamala is not meant to be aging so much since the events of the show)
Ant-Man and the Wasp: Quantumania - set in June or July (iirc), according to a date on-screen, set after GotG HS (Disney+), so solidly in 2026
Guardians of the Galaxy Vol3 - after Quantumania and before Secret Invasion (D+), the latter being set in November 2026, putting GotG v3 around the third quarter of 2026, ideally
Secret Invasion - solidly set in November, must be 2026
The Marvels - solidly set after Secret Invasion; can't be set a long time after Ms.Marvel; according to the director of the film, Kamala is the same age as she is in the show, which cannot be true, due to the setting anyway, but the contradiction can be minimized by just a few months off, if the film is set shortly after Secret Invasion and in the year 2026 (or perhaps early 2027, I don't know what other evidence there is for the film's setting)
This very solidly places stuff like LaT in October 2025, Ms. Marvel in Sep-Oct 2025, Secret Invasion in November 2026, etc. I disagree with some of the settings too, but its canon, and they're not that big of a deal, if you really think about it. There are worse timeline compromises in the MCU.
