The Guardians of the Galaxy movies throw a bit of a wrench into what has so far been a pretty linear cinematic franchise. It’s understood that all of the MCU movies, except for the ones that are period productions and as such are set in the past, are set in the year in which they come out. Iron Man was set in 2008, The Avengers is set in 2012, and so on. But the Guardians of the Galaxy movies are a little different. Guardians 1 takes place in the Earth-year 2014 (although you’d never know it, given the extraterrestrial setting and retro feel), but Guardians Vol. 2 is set only a few months after the first one, so, still in 2014. That sets them a teeny bit apart from the rest of the movies, as, by Infinity War, the Avengers have been cruising through to the year 2018. But it appears that the Guardians will finally be catching up, as James Gunn revealed Vol. 3 will take place after Avengers 4.
