Yeah, it's best to NOT have an official timeline as I doubt at this point it could make much sense.
For one thing, a year between Age of Ultron and Civil War? I know the accident at the start of CW is what really pushed the Accords forward, but surely Tony coming out about creating Ultron would have had those sort of discussions already in place, so either these Accords took really long to get started (and kinda bizarre that a dozen or so dead people seemed to be the final straw when the previous incident cost FAR more lives) or Tony never went public about it which makes him lose any moral ground he has towards Steve in my book if that's the case. Also Ross is still an idiot for bringing up New York and Washington DC, okay just criticize the only people who stopped New York from being nuked (by a trigger-happy council who didn't even wait to see how the Air Force would fare against the alien ships, where's their accords?!) and I guess Steve, Natasha, and Sam should have just let HYDRA kill hundreds of millions of people just so a few dozen to hundreds of accidental casualties in Washington DC when the ships fell don't happen (and they were consulted by Fury who would still technically be SHIELD's leader so this plan was supervised).
Also, Civil War and Black Panther a year apart, uh no, unless CW took place at the end of 2016 and BP the start of 2017 respectively that makes zero sense, they would be having the ceremony as soon as possible so Wakanda has a king.
Also, some of these gaps make the heroes look lazy or just leading uneventful lives. Thor didn't check on Asgard for FOUR YEARS?! The Guardians didn't do anything noteworthy for four years? Man, the Sovereign are really taking their time with their "Adam" plan.....
Yeah, I'm good without ever knowing the timeline, thanks.
