April 11th would be matchday 31....if youre in Rome, go to the Derby
it seems as all matches are being played on that Saturday, most likely due to the holiday i assume. as of now thats how its scheduled at least.
if a move is to be made it usually happens 2 or so weeks ahead, but im not 100% on that.
and finally, im sure no matches in Italy would be played on Good Friday.
