Tomorrow is 2 June June 2nd (or the second of June)

Tomorrow is 2 June and in Italy is the Republic Day. Tomorrow in Italy on June 2nd, it is Republic Day. (un piccolo errore della sintassi) 
This is the day when the Italian people remember the referendum through which we chose a Republic and not a Monarchy, by in the first universal suffrage in Italy.

At Rome, tomorrow morning, Tomorrow morning in Rome the President for of the Italian Republic, Giorgio Napolitano, lays aside (meglio: will lay aside) a laurel wreath at the Altare della Patria  (quando si scrive una parola straniera in una frase inglese, si deve scriverla in corsivo) and there will be a military parade at the Fori Imperiali.

In the afternoon the gardens of Quirinale will be open.
But the 2nd of June is the fearst (???) (forse: for the?) common people too. So many people tomorrow will celebrate the Republic Day with family, going to the beach or in the contryside and doing a having picnics outside the city.
