Each year, according to Wikipedia, Ramadan begins about eleven days earlier than in the previous year.
Thus Ramadan can happen any month of the year.
By using Google I found the following the dates as some kind of proof and hint as to when Ramadan happens:
2012 between 20th of July and 18th of August
2013 between 9th of July and 7th of August
2014 between 28th of June and 27 of July
2015 between 18th of June and 16th of July
