Devils don't come from hell beneath us, they come from the sky

You bought the movie posters for these films:

i) Batman Forever,
ii) The Dark Knight, and
iii) Batman vs. Superman.

However you have forgotten when they were released in theaters, and you are only told that

• Batman Forever was the earliest movie to be released (in terms of year) and was released in the month of June.
• The theatrical release date of The Dark Knight is July 14, 2008.
• The movie released in 2016 was not released in July.

Suppose that the theatrical release years of the three movies are 1995, 2008, and 2016, and their theatrical release months are March, June and July.

Then what is the theatrical release year and month of Batman vs. Superman?
