Spanish days of the week


Have you ever questioned why the names of the days of the week are what they are now? Well, the majority of the days of the week were given their original Greek or Roman names, which were taken from spiritual figures. You will see some Latin and Hebrew linguistic elements too:

  • lunes: luna (the moon)
  • martes: Marte (Roman god of war)
  • miércoles: Mercurio (Roman god of commerce)
  • jueves: Júpiter (Roman god of the sky)
  • viernes: Venus (Roman goddess of love)
  • sábado: sabat (Hebrew word for “rest”)
  • domingo: Dominus (Latin word for “Lord”)

You can learn Spanish fast if you look at the origin of these words and their association with different figures and elements that existed in history. Now that, you know the days of the week in Spanish, it is important for you to understand how they are used in daily conversations as there are some easy rules associated with them.

How do you use the days of the week in Spanish

They are not capitalized

Days of the week in Spanish are never capitalized except if they are used at the start of the sentence.

They are masculine

This means that when you are referring to a day, you must use the masculine articles el, los, un and algunos. For example, if you want to say “the last Friday of the month was rainy” in Spanish, you say “el último viernes del mes fue lluvioso”.

‘On Monday’ cannot be translated into Spanish directly

In English, we use the preposition “on” to discuss events that take place on a particular day. You don’t need to include the word en, or any other preposition, in Spanish, so resist the urge to translate directly.

Use the pronouns el and los to denote “on” when referring to the days of the week. El is used to describe a single occurrence, and los is used to describe something that occurs frequently.

For example:

  • Viene a Madrid el lunes. (She’s coming to Madrid on Monday.)
  • Trabaja todos los sábados. (He works every Saturday.)

You add a‘s’ to make plural

Sometimes, you must refer to the days of the week in the plural. Only if the word does not already end in an s should you add an s to make the days of the week plural. The plural form of the word otherwise remains the same.

The plural forms of the days are:

  • los lunes
  • los martes
  • los miércoles
  • los jueves
  • los viernes
  • los sábados
  • los domingos

Using these rules is essential in holding basic Spanish conversations. Keep them in mind so that you do not end up making errors and mistakes in your Spanish writing. Now we will look at some useful vocabulary words that are associated with the days of the week in Spanish. Make notes as these words are widely used in casual Spanish conversations.
