Questions & Answers about O voo é às oito da noite.
Why do we use às before the number eight?
às is a combination of the preposition a (at) and the feminine plural word for "the", as. We use feminine plural before clock times because we are referring to the hidden word horas (hours). It literally means "at the (eight hours)".
How would I ask "At what time is the flight?" to get this answer?
Why does this sentence use da noite instead of à noite?
When you attach a time of day directly to a specific clock time (like 8:00), you use da manhã (in the morning), da tarde (in the afternoon), or da noite (at night). You only use à noite to mean generally "at night" when you aren't giving an exact hour.
Why use é (from the verb ser) here? I thought times use estar.
We use ser (here as é) because we are stating when a scheduled event takes place. For events like flights, concerts, or meetings, Portuguese always uses ser to express when or where they happen.
