Carlo Tavecchio, the president of the FIGC, wants the 2105-2016 season to end on the 15th of May.  Tavecchio wants the season to end earlier than usual because he wants to give Antonio Conte more time to prepare for the Euros in France.  Sport Mediaset reports that if next season ends early, then next season will require an early start as well.  The 2015-2016 season will most likely start on the 16th of August.
