Learn Spanish (Spain): El quince de agosto es fiesta en toda España. - The fifteenth of August is a holiday in all of Spain.

In Spanish, you use regular counting numbers (dos, tres, quince) for dates instead of ordinal numbers (like second, third, or fifteenth). The only exception is the first day of the month, which is el primero.

Wait, doesn't fiesta mean 'party'? Why not use vacaciones for 'holiday'?

Fiesta does mean 'party', but it is also the standard word for a public or bank holiday. Vacaciones refers to personal time off, like a summer trip or school break. Since August 15th is a national day off, fiesta is the correct word.

Why is it es fiesta and not es una fiesta?

When stating that a day is a public holiday on the calendar, Spanish drops the article and just says es fiesta. If you said es una fiesta, it would sound like you are saying 'it is a specific party' rather than 'it is a public holiday'.

Why is it toda España (feminine) instead of todo España?

Countries ending in '-a' like España are almost always feminine in Spanish. Therefore, the word for 'all' must match its gender, becoming toda. Notice we also don't say toda la España—most countries don't need words like el or la before them.
