/tɾeinta dias/from spelling rules
The English phrase "thirty days" is translated into Spanish as treinta días.

What does it mean word for word?

The phrase is composed of the number treinta (thirty) and the noun días (days).

How does it change in a sentence?

Because días is a masculine plural noun, the number treinta remains in its standard form and does not change for gender.

Did you know?

  • The word día is one of the few nouns ending in -a that is masculine, meaning you say el día instead of la día.
  • Spanish speakers often use the phrase cada quince días to mean 'every two weeks', which is mathematically half of treinta días.
  • In many Spanish-speaking cultures, if a legal or commercial deadline is stated as treinta días, it often refers to 'natural days' (including weekends) rather than 'business days', unless specified otherwise.
