What time is the meeting?
'Riunione' = ryu-NYO-neh. Three syllables; stress the second.
Use anytime you need meeting details. 'Si tiene' (literally 'it holds itself') is the standard Italian phrase for when an event takes place. Knowing this avoids confusion with a direct translation.
'Si tiene' is the reflexive passive form and is the natural, idiomatic way to ask about scheduled events in Italian. Saying 'c'è la riunione alle…?' is also common but 'si tiene' sounds more professional.
La riunione è ancora confermata?
Is the meeting still confirmed?
Use when you have heard the meeting might be rescheduled
Dove si svolge la riunione?
Where does the meeting take place?
'Si svolge' is another key reflexive-passive for events
Chi partecipa alla riunione?
Who is attending the meeting?
Good for understanding the meeting's importance and who to prepare for
Italian business meetings often start 10-15 minutes late and run longer than planned. Do not be alarmed. However, if you are the intern or junior person, arrive a few minutes early to show respect.
