As Rogers watches TV, the Attack in Lagos is stated to be "last month". The Spider-Man: Homecoming Prelude also states that the Bombing of the Vienna International Centre is "one month later", after Lagos. WHiH gave the timeline date for the Lagos incident as May 3, 2016 (see other references), putting the rest of the events of Captain America: Civil War in June. However, in Spider-Man: Homecoming, it jumps forward to "two months later," to the firm date of September 8, 2016. Assuming the 2 is rounded, this still works with June so long as it is very late June. It has to be as late as possible in June, but before schools broke up in New York on June 28th (1, 2), as Parker gets home from school and still has homework to do. In Spider-Man: Homecoming, Stark says that he took Parker for the "weekend," and in an extended version of Peter's video diary it is shown that the day after the Battle at Leipzig-Halle Airport is "Samstag" (Saturday), therefore making the date he picks up Parker Thursday 23rd June, and when he returns him the very early hours of Sunday 26th June. These are the only dates which fit as being a weekend, before schools break up, a rounded 2 months before September 8th, and still the month following the May 3, 2016 Lagos incident, as well as a loose (May to June) "one month" after the incident, thus placing Captain America: Civil War firmly around these dates.
