If he's only been Spidey for 6 months, then when did Ant-Man occur? That movie came out in June of last year, and they made a reference to Spider-Man at the end.
End of Ant Man they show the scene from civil war where they have Winter Solider Captured which is shown in the civil war movie after bucky goes crazy.
Also they show Falcon at the end of Ant Man recruiting Ant Man for what I assume is for Caps side which would place Ant man movie starting just before Civil War and the end of Ant Man happens by the end of Act 1 of Civil War. so the movie is happening just before/same time as civil war.
