The timeline has never been concrete, and always has changed. There’s always debate upon when it takes place, and multiple sources say this or that. But generally, I think I’ve got it.
Captain America The First Avenger: 1942-1945
Captain Marvel: 1995
Iron Man: 2008 (I’ve seen sources sayin 2009, however in the movie there are signs saying 2008)
Iron Man 2: 2010 (There are sources saying six months since the first iron man, however, TIH and the first Thor movie are referenced by coulson, and it’s confirmed they don’t take place in 2008. It makes sense to take place in 2010 as a result.)
Thor: 2010
Incredible Hulk: 2010
Avengers: 2012
Iron Man 3: December of 2012
Thor The Dark World: 2013
Captain America the Winter Soldier: 2014
Guardians Of the Galaxy: August of 2014
Guardians of the Galaxy Vol 2: October of 2014
Age Of Ultron: May 2015
Ant Man: 2015 (A few months after Age Of Ultron, probably July because that’s when the movie are out.)
Captain America Civil War: June 2016
Black Panther: June 2016
Spider Man Homecoming: September or August of 2016
Doctor Strange: First part of the film is February of 2016, then 9 months pass and it ends in November of 2016. (I’ve seen it end in January of 2017, bit I think it makes more sense if it ends when the film comes out.)
Thor Ragnarok: November 2017-Early 2018 (Time passes both on Sakaar and when the statesmen travels through space)
Ant Man and the Wasp: Mid April or Late April of 2018
Infinty War: Late April or Early May (if AMATW takes place in late April) of 2018
Endgame: Because 23 days pass at the beginning of Endgame, it is Late May or Early June. After the 5 year time gap, it is October of 2023.
Spider Man Far From Home takes place in June of 2024.
