Which Day In Spanish? | Say Every Weekday Correctly

You hear day names everywhere: class schedules, doctor appointments, meeting invites, travel tickets, and homework notes. If you mix up martes and miércoles, plans get messy fast. This page gives you the weekday names, how to say them, how to write them, and the patterns that make them stick.

One small relief: Spanish day names don’t change by gender or number the way some adjectives do. You learn seven words, then you learn how Spanish wraps them into real sentences.

Weekday names in Spanish and how they sound

Here are the seven day names in Spanish. Say them out loud as you read. Your mouth learns faster than your eyes.

• lunes (LOO-nes) — Monday
• martes (MAR-tes) — Tuesday
• miércoles (MYAIR-ko-les) — Wednesday
• jueves (HWEH-bes) — Thursday
• viernes (BYAIR-nes) — Friday
• sábado (SAH-bah-do) — Saturday
• domingo (do-MEEN-go) — Sunday

Accent marks matter on miércoles and sábado. They don’t just decorate the word; they show where the stress lands. If you drop the accent in writing, many readers will still get you, but in schoolwork and formal writing it looks sloppy.

Why “jueves” starts with a H sound

In many Spanish accents, j sounds like a strong breathy “h.” That’s why jueves often lands close to “HWEH-bes.” If you’re learning Latin American Spanish, keep it lighter; if you’re leaning toward Spain Spanish, it can sound raspier. Either way, you’ll be understood.

Why “viernes” starts with B

In Spanish, b and v usually share the same sound family. Many speakers produce a soft “b” sound for both. That’s why viernes often starts like “BYAIR-…”. Don’t fight it. Copy a native audio clip and match the rhythm.

Which Day In Spanish? for class and work plans

When you’re asking “what day is it?” Spanish gives you a couple of clean options. Pick one and use it a lot until it feels automatic.

Asking what day it is

• ¿Qué día es hoy? — What day is it today?
• ¿Qué día es mañana? — What day is it tomorrow?
• ¿Qué día es la reunión? — What day is the meeting?

Typical answers use Es + the day name. Add hoy if you want to be extra clear.

• Es lunes.
• Hoy es jueves.
• Es sábado.

Planning with “el” and “los”

This is where many learners get stuck. Spanish often puts an article in front of the day name.

• el + day = one specific day, often the next one coming
• los + plural day = a repeated habit

Try these patterns:

• Nos vemos el martes. — See you on Tuesday.
• La clase es el miércoles. — The class is on Wednesday.
• Los viernes trabajo desde casa. — On Fridays I work from home.
• Los sábados estudio por la mañana. — On Saturdays I study in the morning.

Using “de” for ranges

To say you do something from one day to another, Spanish loves de:

• De lunes a viernes — Monday through Friday
• De martes a jueves — Tuesday through Thursday
• De sábado a domingo — Saturday through Sunday

You can plug those ranges into daily life:

• De lunes a viernes tengo clases.
• De martes a jueves entreno.

“Entre semana” and “fin de semana”

Two phrases help you talk about the week as blocks:

• entre semana — during the workweek
• el fin de semana — the weekend

They’re handy when you don’t care which exact day it is.

Writing days of the week correctly

Spanish day names usually start with a lowercase letter. That’s true even in formal writing. The main exceptions are when the word starts a sentence or appears in a title where capitalization rules differ.

The Real Academia Española states that day names are common nouns and are written with lowercase initial letters in regular text. RAE guidance on lowercase for weekdays and months explains the rule and the usual exceptions.

Spanish learners who write English a lot often capitalize Lunes out of habit. In Spanish, lunes is the normal form. That one detail can make your writing look more natural right away.

Dates with weekdays

In letters, school notices, and formal documents, you may see the weekday placed before the date. Spanish often uses commas less than English in date lines, so it can look different at first.

• lunes 3 de marzo
• viernes 18 de julio

The Centro Virtual Cervantes has a long-running language forum that reinforces the same lowercase rule for weekdays in date writing. CVC note on writing dates and weekday names mentions the lowercase convention in context.

Common abbreviations you’ll see

Messages and timetables often shorten day names. Abbreviations vary by country, school, and workplace. Still, a few show up a lot:

• lun. lunes
• mar. martes
• mié. miércoles
• jue. jueves
• vie. viernes
• sáb. sábado
• dom. domingo

Notice the accent remains in shortened forms like mié. and sáb. when writers keep accents. Some people drop them in quick notes. In graded work, keep them.

Day names, articles, and real sentence patterns

Memorizing the list is step one. Step two is using the words the way Spanish uses them. Here are the patterns that show up all week long.

One-time plans

• El jueves tengo examen.
• La cita es el lunes.
• ¿Te va bien el viernes?

Habits and routines

• Los lunes estudio con mi grupo.
• Los miércoles trabajo tarde.
• Los domingos llamo a mi familia.

Talking about “this” and “next”

Spanish has a couple of ways to say “this Monday” or “next Monday.” Usage shifts by region, so keep it plain when you can. These are widely understood:

• este lunes — this Monday
• el lunes que viene — the Monday coming up
• el próximo lunes — next Monday (can be read two ways in some places)

If you’re writing a schedule where confusion costs money, add the date. “El lunes 12” beats “el próximo lunes” every time.

Weekdays at a glance

Spanish Day	English Match	Fast Use Pattern
lunes	Monday	el lunes / los lunes
martes	Tuesday	el martes / los martes
miércoles	Wednesday	el miércoles / los miércoles
jueves	Thursday	el jueves / los jueves
viernes	Friday	el viernes / los viernes
sábado	Saturday	el sábado / los sábados
domingo	Sunday	el domingo / los domingos

If your brain mixes the middle of the week, anchor it with one sentence you’ll actually say. Pick something tied to your routine, then repeat it for a week.

• Los martes tengo clase.
• El miércoles estudio.
• El jueves descanso.

Memory moves that don’t feel like studying

You don’t need fancy tricks. You need tiny reps that happen in real life. These habits work because they force recall, not just recognition.

Use your phone calendar in Spanish

Switch your phone calendar language to Spanish for two weeks. Then read each weekday out loud once a day. You’ll stop translating and start noticing patterns.

Say the day before you check it

When you wake up, guess the day in Spanish, then confirm it. That one moment of recall builds a stronger memory than rereading a list.

Make a two-line mini diary

Write two short lines each night:

• Hoy es ____.
• Mañana es ____.

Keep it on paper. Your hand adds a second learning channel.

Pair days with repeating actions

Link each day to a real event you already do. No creativity required.

• Los lunes: your first class
• Los miércoles: laundry day
• Los viernes: a weekly call

After a few cycles, the word and the action fuse.

Common mix-ups and how to fix them fast

Most weekday errors fall into a few buckets. Fixing them is easier than you think.

Martes vs. miércoles

They’re both “M” days, and they sit back-to-back. Use the accent as a visual flag: miércoles carries an accent, martes doesn’t. In speech, stretch the first syllable of miércoles a touch: “MYAIR-…” helps your ear separate it.

Sábado vs. domingo

Weekend words often blur when you’re speaking fast. Lock one phrase in your head:

• el sábado — often the “plans” day
• el domingo — often the “rest” day

Even if your weekend looks different, those labels help your brain grab the right word.

Capital letters from English

This is a writing habit, not a vocabulary problem. Scan your drafts once for capital letters on day names. If you see them mid-sentence, switch to lowercase.

Quick practice blocks for speaking and writing

Use these as mini drills. Read them once, then cover them and try to say them from memory.

Seven-day speak-aloud set

• El lunes trabajo.
• El martes estudio.
• El miércoles tengo clase.
• El jueves salgo temprano.
• El viernes ceno con amigos.
• El sábado descanso.
• El domingo preparo la semana.

Make it plural

Now flip each one into a habit by changing el to los and the verb tense if you want. Your brain learns the grammar through repetition.

Weekday writing checks for schoolwork

Before you submit a homework assignment, run through these checks:

• Accents: miércoles, sábado
• Lowercase day names inside sentences
• Articles: el for one day, los for habits
• Ranges: de lunes a viernes when you mean Monday through Friday

That’s it. If you can do those four, your weekday Spanish will look clean and sound natural.

Weekday phrases you can reuse anywhere

What You Want To Say	Spanish Phrase	When It Fits
What day is it today?	¿Qué día es hoy?	Daily talk
It’s Monday.	Es lunes.	Answering a date check
See you on Thursday.	Nos vemos el jueves.	Making a plan
I study on Wednesdays.	Los miércoles estudio.	Habits
Monday through Friday	De lunes a viernes	Schedules
On the weekend	El fin de semana	Weekend plans

If you want one tiny routine that pulls it all together, do this: each Sunday night, write your week plan using de lunes a viernes, then add one line for el sábado and one for el domingo. You’ll practice ranges, articles, and the words themselves in under two minutes.
