Pretty sure Endgame started in 2019 and ended in 2023. From there it gets hard to tell, but I do remember some specific dates being mentioned in a few things.
Wandavision takes place weeks after Endgame, three or six weeks I forget which. So 2023.
Falcon & Winter Soldier takes place six months after Endgame. So either late 2023 or early 2024, depending on what time of year Endgame finishes in. I think it was spring?
Hawkeye states that Ronin hasn't been seen for a "couple years" so it's probably 2025 or so.
I don't recall any other shows or films giving precise dates in relation to Endgame.
