Learning how to say the days of the week in Spanish is an important step towards having a functional vocabulary in the language!

Let’s get started!


Spanish Days of the Week


Now that you know what the days of the week are, have you ever wondered why they have the names they have? 

Well, most days of the week were named according to its original Greek/Roman name that originated 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”)

How to Use the Days of the Week

Days of the week are not capitalized in Spanish

The only exception to this would be, of course, if they appear as the first word of a sentence.

All days of the week are masculine

Not up to speed on Spanish gender? Here’s your refresher.

This means that when you’re referring to a day, you must use the masculine articles el, los, un and algunos.

“On Monday” doesn’t translate directly into Spanish

In English, we use the preposition “on” to talk about something happening on a specific day. Resist the urge to translate directly—in Spanish, you don’t need to insert the word en, or any other preposition, for that matter!

When talking about days of the week, use the pronouns el and los to mean “on.”

Use el when talking about one single occurrence, and the plural los when talking about something that happens habitually.

Viene a Madrid el lunes.
(She’s coming to Madrid on Monday.)

Trabaja todos los sábados.
(He works every Saturday.)

You only add s to make a day of the week plural if it doesn’t already end in s

Sometimes, you need to talk about days of the week in the plural, like in the previous example (todos los sábados).

When making days of the week plural, only add an s if the word doesn’t already end in s. Otherwise, the word stays the same in the plural form.

So, the plural forms of the days are:

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

Learning Tips

  • Write the full date every day. Putting the date down in writing every day will help you remember the words and their correct order.
  • Learn with a song. YouTube is chock-full of “days of the week” songs in Spanish. Here’s one, and here’s another.
  • Make up an acronym. Use the first letter of each day and create your own acronym to help you remember them. For example, Little Mice Make Jolly Vikings Slam Doors. Yes it’s nonsensical, but that’s exactly what makes it so memorable.
  • Switch your phone to Spanish. Changing your settings to make your phone speak to you in Spanish can be a great way to passively practice your language skills throughout the day. 
  • Use authentic media to learn. One of the best ways to learn Spanish is through immersion—that is, by exposing yourself to as much authentic Spanish as you can. FluentU is a great option for this as they provide hundreds of authentic clips with subtitles, flashcards and more!
