Cultural Tip
In many Spanish‑speaking countries, the word 'fiesta' can refer to anything from a small family gathering to a large public celebration. When asking about a party, it's polite to use the formal '¿Qué día es la fiesta?' if you don't know the person well, but among friends the informal tone works just as well. Also, note that some regions prefer '¿Cuándo es la fiesta?' when the exact calendar date is less important than the time of day.
