Days of the Week in Spanish: The Quick Reference Guide (Monday to Sunday)

Most Spanish classes hand you a list, make you repeat it a few times, and move on. And for a while, that works fine...until a native speaker asks "¿Nos vemos el jueves?" and your brain goes completely blank trying to figure out which one jueves is.

The days of the week in Spanish are genuinely simple. There are only a few grammar rules that actually matter, and once those click, you can read Spanish calendars, make plans, and talk about your schedule without pausing to translate. Here’s everything you need, without the filler.

What are the days of the week in Spanish?

Here are all seven days of the week in Spanish, in order from Monday to Sunday:

The first thing to notice: Spanish days of the week are never capitalized. Not mid-sentence, not in titles. "Hoy es lunes" — always lowercase. Write "Lunes" with a capital L, and it looks wrong to any native speaker.

Two days have accent marks (tildes)  worth knowing: miércoles (Wednesday) and sábado (Saturday). The accent tells you where the stress falls. Drop it in a formal email or school assignment, and it counts as a misspelling, even if no one will misread it.

How to pronounce Spanish days of the week

Here's how to say each day of the week in Spanish without the textbook awkwardness:

Spanish is phonetic, which means once you know the sounds, you read everything correctly. The trickiest one is miércoles, with its three syllables and stress on the first syllable. Say it out loud a couple of times, and it sticks fast.

Where do the Spanish names of the week come from?

The first five weekdays in Spanish are named after planets and Roman gods, the same system used across all Romance languages.

• Lunes comes from luna (the Moon)
• Martes comes from Mars, the Roman god of war
• Miércoles comes from Mercury
• Jueves comes from Jupiter (Jove in Latin)
• Viernes comes from Venus

Saturday and Sunday break the pattern. Sábado comes from the Hebrew Shabbat (day of rest), and domingo comes from the Latin Dominus, meaning Lord's Day. If you already know French or Italian, these will feel familiar — all Romance languages inherited the same naming system from Latin.

Spanish Grammar Rules For Days Of The Week

Three rules cover 90% of what you'll use in real conversation.

1. All days are masculine

Every day of the week in Spanish is a masculine noun. Use el for singular and los for plural. No exceptions here.

2. Use "el" or "los" instead of "on"

Spanish doesn't use a preposition before days the way English uses "on." The article handles that:

• "Voy al gym el lunes" = I'm going to the gym on Monday
• "No trabajo los viernes" = I don't work on Fridays
• "Hoy es martes" = Today is Tuesday (no article needed with ser)

3. Only sábado and domingo add -s for plural

The five weekdays already end in -s, so they stay the same whether singular or plural. The weekend days are the only ones that change:

That's it. Three rules, and you're covered for everything day-related in Spanish.

What Day Does the Spanish Week Start On?

Monday. Not Sunday. Open any Spanish calendar and lunes is the first column. This matters when someone says "this week" or "next week" in Spanish — they're counting from Monday. The workweek runs lunes through viernes, and el fin de semana (the weekend) is sábado and domingo.

One cultural detail worth knowing: in Spanish-speaking countries, Tuesday the 13th is the unlucky day, not Friday the 13th. There's even a saying — "En martes, ni te cases ni te embarques" — don't get married or board a ship on a Tuesday. It probably won't come up in daily life, but it's the kind of thing that makes you sound like you actually know the culture.

Spanish Days of the Week Abbreviations

Spanish uses single-letter abbreviations on calendars, schedules, and apps:

Wednesday gets X to avoid confusion with M for martes. If you see "L-M-X-J-V" on a gym schedule or school timetable, that's Monday through Friday. Two-letter versions (Lu, Ma, Mi, Ju, Vi, Sa, Do) also exist, though the single-letter system is far more common on Spanish calendars.

Common Phrases Using Days of the Week

Knowing the words gets you halfway there. These are the phrases that actually come up in conversation:

• "¿Qué día es hoy?" — What day is today?
• "Hoy es lunes" — Today is Monday
• "Mañana es martes" — Tomorrow is Tuesday
• "Nos vemos el sábado" — See you Saturday
• "Los jueves tengo clase" — I have class on Thursdays
• "El próximo viernes" — Next Friday
• "El miércoles pasado" — Last Wednesday
• "¿Qué haces el domingo?" — What are you doing on Sunday?

Swap any day into these structures and they work exactly the same. Once you recognize the pattern, building time-related sentences becomes automatic.

Common Mistakes to Avoid

Using "en" instead of "el"

• Wrong: "Tengo cita en el lunes"
• Right: "Tengo cita el lunes"

Capitalizing the days

• Wrong: "Hoy es Martes"
• Right: "Hoy es martes"

Adding -s to weekdays for plural

• Wrong: "Los luneses"
• Right: "Los lunes"

Skipping the accent marks in writing

Miércoles and sábado need their accents in anything formal. It's a small habit worth building early.

The Best Way to Actually Learn the Days

Flashcards can help you recognize the Spanish days of the week. Real content helps you use them.

When you hear "nos vemos el viernes" in a Spanish show, or "los lunes son terribles" in a podcast, your brain stores the phrase with context — not just a translation floating in a vacuum. That's the difference between knowing a word and actually knowing how to use it.

You watch real Spanish-language TV shows and movies with interactive subtitles: click any word you don't recognize and get an instant definition. Days of the week come up constantly in natural dialogue, like when scheduling meetings, making weekend plans, and complaining about Monday mornings.
