The days of the week in Spanish are lunes (Monday), martes (Tuesday), miércoles (Wednesday), jueves (Thursday), viernes (Friday), sábado (Saturday), and domingo (Sunday), the same seven words everywhere Spanish is spoken, Mexico and Spain included. The Spanish week starts on lunes rather than Sunday, and every name stays lowercase mid-sentence.

Where the day names come from
Five of the seven weekday names carry sky names hidden inside them: lunes comes from Luna, the moon; martes from Mars; miércoles from Mercury; jueves from Jupiter; and viernes from Venus. The weekend breaks the pattern: sábado traces back to the Sabbath, and domingo to the Latin for the Lord's day, dies dominica. Knowing the roots will not change how you use the words, but it is the kind of hook that makes five names in a row easier to keep straight.
How to say 'on Monday' and 'on Mondays'
To say on a day, Spanish skips the word for on and reaches for the article instead: el lunes means on Monday, and los lunes means on Mondays, every week. The five weekdays already end in -s and keep the same shape in the plural, so el martes becomes los martes with no change, while sábado and domingo add one: los sábados, los domingos. Nos vemos el jueves means see you on Thursday; trabajo los sábados means I work on Saturdays.
Is Monday the first day of the week in Spanish?
Yes. When Spanish lists the days in order, from a classroom chart to a printed calendar, it starts with lunes and ends with domingo, following the Monday-first convention used across the Spanish-speaking world. That is a different order from calendars in the United States, which typically start the week on Sunday, so a Spanish weekly grid can look shifted by one column to a US eye at first glance.
Are the days of the week different in Mexican Spanish?
No. Mexico uses the same seven words as Spain, Argentina, or any other Spanish-speaking country: lunes, martes, miércoles, jueves, viernes, sábado, domingo. Unlike some everyday vocabulary that shifts by region (a bus or a straw can go by several different names across Latin America), the days of the week do not vary. There is no separate Mexican Spanish list to learn.
Are the days of the week capitalized in Spanish?
No. Spanish writes all seven day names lowercase in the middle of a sentence, nos vemos el jueves, and saves capitals for the start of a sentence. Months follow the identical rule: if you are asking are months capitalized in Spanish, the answer is also no, and that page covers days, months, languages, and nationalities together in one place. For the months themselves, enero through diciembre, see the months guide.
Let the calendar do the reviewing
The days of the week return every single week, which makes them some of the easiest words to keep once you have them. Vocabcord does not add a study schedule on top of that natural repetition, it uses it: every time you plug in your phone to charge, one phrase plays out loud, drawn from your level and spaced so a word returns right before it fades. Say el viernes to yourself as the weekend gets close, and let the app cover the rest of the week in between. Get Vocabcord on the App Store and start with lunes today.
