The Days of the Week in Spanish

Hola a todos! By the end of this short article, you will be able to read, pronounce and understand the days of the week in Spanish. It is important to learn these seven words at an early stage of your Spanish learning journey.

Obviously, knowing the days of the week in Spanish will definitely be useful later. So, it’s time to learn seven little, easy words that you’ll use over and over when speaking Spanish throughout your life.

The Days of the Week: Los días de la semana

Firstly, let’s remember that ‘The Days of the Week’ in Spanish is as follows: Los días de la semana.

Secondly, remember that the days of the week in Spanish are not capitalised.

Thirdly, remember that days of the week in Spanish are masculine, not feminine.

If you are unsure about the rules of masculine and feminine in Spanish then you can find more information in our Spanish for Beginners Course.

So, let’s go through the days of the week in Spanish. 

Monday – lunes

“Monday” in Spanish is ‘lunes’

So, Monday is Spanish is lunes, which comes from the word luna for “moon.” You will find it easy to remember if you remember this root of the word.

Monday is lunes!

It is useful to remember that, in Spanish, lunes is the first day of the week. At least, that’s when the calendar starts. This is also the case in German!

In English, we start our days of the week with Sunday. In all Spanish speaking countries, Saturday and Sunday are very much days of rest.

Tuesday – martes

“Tuesday” in Spanish is ‘martes’

The majority of days of the week, in most languages, come from the names of gods of mythology.

Here’s the important part: “Tuesday” in Spanish is martes. This comes from Mars (the Roman god of war). So, the easiest thing to remember Tuesday in Spanish is to remember the Roman god of war. Remember the following:

Tuesday is martes!

Wednesday – miércoles

“Wednesday” in Spanish is ‘miércoles’

As mentioned, many days of the week in Spanish, and other languages, derive from Roman gods. In Spanish, “Wednesday” is miércoles. What’s the easiest way to remember this? Well, Wednesday is named after Mercury, the Roman god of financial gain and trickery!

So, remember, miércoles – Mercury. Can you see the resemblance? Repeat this aloud:

Wednesday is miércoles!

Thursday – jueves

“Thursday” in Spanish is ‘jueves

You get the gist by now – many days of the week in Spanish derive from Roman gods. Believe it or not, “Thursday” is no different. This name derives from Jupiter. Thursday in Spanish is jueves.

Thursday and Jupiter don’t look alike, though. This is because, in English, Thursday comes from Thor’s day. Thor and Jupiter are both gods of thunder.

So, remember:

Thursday is jueves!

If you are reading this, it is likely that you are wondering about pronunciation of many of these days of the week in Spanish. Particularly, jueves.

In Spanish, the j is pronounced like an English h. So, the pronunciation is as follows – ‘hueves.’

Friday – viernes

“Friday” in Spanish is ‘viernes’

An online source informs me that viernes derives, or is named after, the goddess of love and beauty, Venus.

So, remember this:

Friday is viernes!

Saturday – sábado

“Saturday” in Spanish is ‘sábado’

Now, all we need to remember is the weekend days, given that we have been through the first five days of the week in Spanish.

In Spanish, “Saturday” is sábado. Can you think what this is named after, or how you might remember it? Well, sábado is named after the “Sabbath.” By contrast, in English, Saturday comes from Saturn.

In Abrahamic religions, the Sabbath is a day set aside for rest and worship. You may not be a religious person, but if you lead a ‘normal’ life, it is likely that Saturday is your first day of rest.

So, remember this:

Saturday is sábado!

Sunday – domingo

This brings is to our final day of the week in Spanish – Sunday. “Sunday” in Spanish is domingo.

This comes from the Latin root Domenica. This means “the Lord’s Day” in Latin. Another way to remember this is to remember the capital city of the Dominican Republic – Santo Domingo.

So, remember:

Sunday is domingo!

Days of the Week in Spanish: A Recap

Some Rules to Remember

You may remember that at the start of this article, we mentioned that days of the week in Spanish are all masculine in gender. Furthermore, remember that they are not capitalised. So, unless you are starting a sentence, each day of the week will start in lower case.

Another Rule to Remember

The definite article is not used after the verb ser, but at all other times it is required and there is slight change in meaning if it is singular or plural: el lunes = on Monday but los lunes = on Mondays.

If you are unsure about definite articles, verbs and how to use them, then you can find further information in our Spanish for Beginners course.
