Italian for beginners

I just did an Italian lesson on museums & events and they seem to have left out the oh-so-important question, 'When are y'all open (tomorrow/Saturday/etc.)?

Would it be something like...

Quando aperto (domani)?
Cosa sono l'orario di apertura (sabato)?

And then they'd answer with 'dalle...alle....'?

If anyone can recommend a good, oft-frequented Italian for beginners community, I'll take my silly little questions over there.
