Days of the week are masculine

Days of the week in Spanish are always masculine.

Read and listen to these examples:

El lunes estudio matemáticas.
I study maths on Monday.

El martes voy al gimnasio.
I go to the gym on Tuesday.

El domingo cocino una paella.
I cook a paella on Sunday.

In the examples above, note that we use el in order to say on in English. when we are talking about when things take place.

Andrea juega al badminton los viernes.
Andrea plays badminton on Fridays.

Los lunes suelo tener más trabajo en la oficina.
On Mondays I usually have more work at the office.

In these examples, we are still talking about when things take place. Notice how we can also use the plural articles (los). This is used as in "every [day of the week]".

This would be incorrect:

En lunes voy al gimnasio.
En sábados voy al gimnasio.

 

Days of the week in Spanish are never capitalized!

Unlike in English where all days of the week have a plural form, days of the week in Spanish do not have a plural form, except for sábados and domingos. All the other days of the week indicate the plural only by the plural article. For example, this is incorrect:

Los marteses voy a la biblioteca.
On Tuesdays I go to the library.

Los marteses voy a la biblioteca. Is this a contradiction to the rule i.e. "Days of the week do not have a plural form except sabados y domingos."

Hola Ronald,

Yes, the days of the week only have one form for both singular and plural (except for sábado and domingo). You don't need to add -es, so:

Los lunes juego al baloncesto. (On Mondays I play basketball) - plural

Cada lunes juego al baloncesto. ( Each Monday I play basketball) - singular

Hola Ronald - if you look the -ES ending of the "wrong example" is crossed out. I'll add "this is wrong" before it just to make extra sure students realise we are giving a wrong example  here.
