Martes is Spanish for Tuesday, pronounced “MAR-tes,” and it’s normally written with a lowercase m.
If you’ve seen martes in a calendar, a class schedule, or a chat message, you already know the feeling: you can read it, but you pause before you say it out loud or write it yourself. This post clears that up. You’ll learn what martes means, how to pronounce it, how to write it correctly in a sentence, and how Spanish speakers use it in daily scheduling.
You’ll also get a set of ready-to-steal phrases (texts, emails, and spoken lines), plus a short checklist to avoid the mistakes that show up most in English-to-Spanish writing.
What Martes Means In A Weekly Schedule
Martes is the name of the weekday that comes after lunes (Monday) and before miércoles (Wednesday). The RAE dictionary entry for “martes” also notes its Latin origin: dies Martis, linked to Mars.
In practical terms, that origin rarely matters for day-to-day Spanish. What matters is using the word the way people expect to see it: lowercase in running text, no accent mark, and paired with the right prepositions when you’re talking about plans.
Lowercase Rules That Trip People Up
In Spanish, weekday names are common nouns, so they’re written in lowercase in normal sentences. The RAE note on lowercase for weekdays gives clear examples like “Nació el pasado martes…”.
You’ll still see capital letters in two cases:
- Start of a sentence: “Martes tengo examen.”
- Titles and headers: a calendar heading or a menu label where style rules vary.
Outside those spots, stick with martes. Fundéu also repeats the same guidance in its note on weekday names in lowercase.
Pronunciation That Sounds Natural
Say it as two clean syllables: MAR + tes. The stress lands on mar-. The r is the light Spanish tap, close to the tt sound in “butter” for many American English speakers. The final s is clear in most dialects, so don’t swallow it.
If you want a quick self-check, record yourself saying “martes, miércoles” back-to-back. If you can keep mar- and miér- crisp, you’re on track.
Martes In Spanish Days: Spelling, Accent Marks, And Abbreviations
This is where a lot of learners slip, mostly because English habits sneak in. Here are the rules you can rely on.
Do You Put An Accent On Martes?
No. It’s written martes, with no accent mark. The stress pattern follows standard Spanish rules: words ending in a vowel, n, or s are stressed on the second-to-last syllable unless a written accent says otherwise. Martes fits that pattern, so it stays plain.
Does Martes Change In Plural?
Weekday names can be used in plural when you mean “on Tuesdays,” like a repeating plan. In many styles, you’ll still see the same form, especially in set phrases. In others, you may see los martes treated as a fixed expression. If you’re writing for general learners, the safest, most common pattern is:
- Los martes + verb: “Los martes trabajo desde casa.”
That reads naturally across Spanish-speaking regions.
Common Abbreviations In Calendars
Calendars and timetables often shorten weekdays. You might see mar. or mar for Tuesday, depending on the layout. Treat these like labels: keep them consistent inside one schedule, and make sure the meaning is clear from context.
Use Martes In Real Sentences
Knowing the translation is one thing. Using it smoothly is another. Spanish tends to pair days with small prepositions that signal whether you mean a single date, a repeating routine, or a time window.
El Martes Vs Los Martes
El martes often points to a single Tuesday that’s coming up or just passed, usually when the time frame is obvious in the chat or story.
- “El martes te llamo.”
- “El martes pasado tuve una reunión larga.”
Los martes is the go-to for repeating routines.
- “Los martes hay clase de yoga.”
- “Los martes cenamos temprano.”
On Tuesday: El Martes Or El Próximo Martes
English often uses “on” with days. Spanish usually drops the direct equivalent and lets the article carry the meaning. When you need to be clearer, add a time marker.
- “El martes” (this coming Tuesday, in many chats)
- “Este martes” (this Tuesday, near-term)
- “El próximo martes” (the next Tuesday)
If you’re booking something, spelling it out keeps things clean. A short extra phrase saves back-and-forth.
From Tuesday To Thursday
To show a range, Spanish uses de…a… or del…al… with the day names:
- “De martes a jueves trabajo en la oficina.”
- “Del martes al jueves hay descuentos.”
If you need a style note for formal writing, the RAE’s orthography section on time and date references treats weekdays as lowercase common nouns in standard text.
Mistakes People Make With Martes
Most errors come from three places: English capitalization habits, accents added by guesswork, and calendar shorthand copied without thinking. Here’s how to spot the problem fast.
Capitalizing Martes In Mid-Sentence
Wrong: “Nos vemos el Martes.”
Right: “Nos vemos el martes.”
Adding An Accent: Martés
Wrong: “Martés”
Right: “martes”
Mixing Up Tuesday With March
In English, “Tue” and “Mar” can both show up in calendars, and “Mar” can also mean March. In Spanish, March is marzo, so mar. as a weekday abbreviation points to Tuesday, not the month. If you’re translating a schedule, scan for this before you hit send.
Spanish Weekday Quick Reference
When you learn martes, it helps to lock it into the full week so you don’t hesitate mid-sentence. The table below gives the full set, plus a simple pronunciation cue and a short note that shows how it behaves in writing.

|---|---|---|
| lunes | LOO-nes | Lowercase in sentences |

| miércoles | MYAIR-ko-les | Accent on é |
| jueves | HWEH-bes | J is a breathy sound |
| viernes | BYAIR-nes | Lowercase in sentences |

Martes In Dates, Invitations, And Messages
Now let’s turn the rules into messages you can paste. The goal is to sound natural while staying clear about timing. These patterns work in texts, emails, and spoken Spanish.
Simple Text Messages
- “¿Te va bien el martes a las 6?”
- “El martes no puedo. ¿Y el miércoles?”
- “Perfecto, quedamos para el martes.”
Work Or School Scheduling
- “La reunión es el martes a las 10.”
- “Entrego el trabajo el martes por la mañana.”
- “El martes tengo clase, pero el jueves estoy libre.”
Invitations That Sound Friendly
- “El martes hacemos cena en casa. ¿Te apuntas?”
- “¿Café el martes después del trabajo?”
- “El martes celebramos tu cumple. Ven si puedes.”
Writing A Full Date In Spanish
Spanish date lines often look like this: “martes, 22 de noviembre”. You’ll see the weekday first, then a comma, then the day number and month. Keep weekday and month lowercase inside the line, unless it starts the full sentence. If you’re copying a formal date line, keep the punctuation and spacing consistent.
Tuesday 13 And The Phrase Martes Y Trece
If you spend time with Spanish speakers, you may hear “martes y trece” in jokes or warnings. It points to Tuesday the 13th, a date that many people treat as unlucky in parts of the Spanish-speaking world. You don’t need to believe it to understand it. It’s used like a quick wink when something goes wrong on a Tuesday or when a plan feels jinxed.
Two ways it shows up:
- “Hoy es martes y trece… mejor me quedo en casa.”
- “Con mi suerte, seguro que cae en martes y trece.”
If you’re translating or writing subtitles, keep it as a set phrase. A literal “Tuesday and thirteen” sounds odd in English, so translators often switch to “Friday the 13th” for the same vibe, depending on the audience.
Common Martes Phrases You’ll Hear
These are short expressions that put martes in context. Some are plain scheduling lines. Others are habits that show up in shops, gyms, and workplaces.
| Spanish Phrase | Natural English | Use Case |
|---|---|---|
| el martes por la mañana | Tuesday morning | Plans and deadlines |
| el martes por la tarde | Tuesday afternoon | Casual meetups |
| el martes por la noche | Tuesday night | Dinners and events |
| los martes | on Tuesdays | Recurring routines |
| este martes | this Tuesday | Near-term scheduling |
| el próximo martes | next Tuesday | Clarity in booking |
| de martes a jueves | Tuesday through Thursday | Ranges and hours |
| martes y trece | Tuesday the 13th vibe | Jokes and warnings |
| cierra los martes | closed on Tuesdays | Shop hours |
A Fast Checklist To Get Martes Right
Before you send that message or publish that line, run this quick check. It takes ten seconds and keeps your Spanish looking clean.
- Meaning: You’re pointing to Tuesday, not March (marzo).
- Spelling: It’s martes, no accent mark.
- Case: Lowercase in running text unless it starts the sentence.
- Schedule style: Use el martes for one Tuesday, los martes for a routine.
- Range: Use de martes a… or del martes al… for a window.
Practice Prompts You Can Do In Two Minutes
If you want this to stick, write five lines using martes in different ways. Keep them short. Read them out loud once. Done.
- One plan for a single Tuesday: “El martes…”
- One routine: “Los martes…”
- One time range: “De martes a…”
- One message that moves the plan: “¿Te va bien el martes…?”
- One date line: “martes, __ de __”
Do that a couple of times, and you’ll stop hesitating. Your brain will treat martes as a familiar label, not a tricky vocabulary item.
