Whether you are booking a flight to Madrid, filling out a form in Mexico City, or simply telling a new friend when your birthday is, you will need the calendar. Learning the months of the year in Spanish is one of the fastest wins for any beginner: there are only twelve words, many look almost identical to their English cousins, and once you know them you can talk about dates, seasons, holidays, and plans with confidence.

In this guide you will find all twelve months with clear pronunciation, the one grammar rule English speakers always get wrong (capitalization), how to write and say dates, how the seasons line up, which preposition to use, and a handful of memory tricks that make the whole list stick. Let’s open the calendar.

The 12 Months of the Year in Spanish

Here is the complete list. Notice how closely the Spanish and English versions resemble each other — that shared Latin ancestry means you already recognize most of them. The pronunciation column uses simple English-style syllables, with the stressed syllable in capital letters.

The Spanish word for “month” itself is el mes (plural los meses), and the word for “year” is el año. So los meses del año literally means “the months of the year.” All twelve month names are masculine, so they pair with el: el enero pasado (last January), un diciembre frío (a cold December).

How to Pronounce the Months in Spanish

Spanish spelling is wonderfully consistent: once you learn the sounds of the letters, you can read any word aloud. A few points will smooth out your accent when you say the months.

The letter J sounds like an English H

In junio and julio, the J is not pronounced like the English J in “jam.” Instead it makes a breathy H sound from the back of the throat — closer to the H in “hello.” So junio is “HOO-nyoh,” not “JOO-nee-oh.”

Spain vs. Latin America: the C and Z

In marzo and diciembre, the Z and the soft C are pronounced differently depending on where you are. In most of Spain, they sound like the “th” in “think” (so marzo becomes “MAR-tho”). In Latin America, the same letters sound like a plain S (“MAR-soh”). Both are correct — choose whichever region you are learning for and stay consistent.

Rolling into the -iembre endings

Four months share the -iembre or -ubre ending: septiembre, octubre, noviembre, diciembre. Practice them as a group. The stress always falls on the syllable before that ending, which keeps the rhythm predictable. If you can already say the days of the week in Spanish, you will notice the same clean, syllable-timed rhythm at work here.

Why the Months Are Not Capitalized in Spanish

This is the single most common mistake English speakers make. In English we always capitalize months — January, February, March. In Spanish, we do not. The months are treated like ordinary common nouns, so they are written entirely in lowercase unless they happen to begin a sentence.

• Correct: Mi cumpleaños es en abril. (My birthday is in April.)
• Incorrect: Mi cumpleaños es en Abril.
• Correct at the start of a sentence: Julio es mi mes favorito. (July is my favorite month.)

The same rule applies to the days of the week and the seasons — all lowercase. This is confirmed by the Real Academia Española, the official authority on Spanish spelling and grammar. Getting this small detail right instantly makes your writing look more natural to native speakers.

How to Write and Say Dates in Spanish

Once you know the months, writing dates is easy because Spanish follows one reliable formula:

el + [day] + de + [month] + de + [year]

For example, American Independence Day is written el 4 de julio de 1776 and read aloud as “el cuatro de julio de mil setecientos setenta y seis.” Notice three things:

• The day comes before the month — the opposite of the common U.S. order. So 5/8 in Spain means the 5th of August, not May 8th.
• You link the parts with the little word de (“of”).
• Cardinal numbers are used for the day (uno, dos, tres…), not ordinals — except sometimes the first, which can be el primero de mayo in parts of Latin America.

To ask the date, say ¿Qué fecha es hoy? or ¿A cuántos estamos? A typical answer: Hoy es el 15 de septiembre. If you want a deeper dive into numbers and everyday phrasing to complete your dates, our list of basic Spanish words and phrases is a perfect companion.

Using the Preposition “en” with Months

To say that something happens in a certain month, Spanish uses the preposition en — and, unlike English, you do not need an article. Just place en directly in front of the month:

• Voy a viajar en marzo. — I am going to travel in March.
• Las clases empiezan en enero. — Classes start in January.
• Nos casamos en octubre. — We are getting married in October.

You will also hear the fuller phrase en el mes de… for emphasis or formality: en el mes de diciembre (in the month of December). Both are correct; en + [month] is simply the shorter, more common option in daily speech.

The Four Seasons in Spanish (Las Estaciones)

Months and seasons go hand in hand, so it helps to learn las estaciones del año at the same time. Note that seasons, like months, are written in lowercase. The table below shows the seasons for the Northern Hemisphere — remember that in countries like Argentina and Chile the seasons are reversed.

Try building sentences that combine both: En verano hace mucho calor (In summer it is very hot) or Me encanta la primavera porque hay muchas flores (I love spring because there are many flowers). Describing that scenery is even easier once you know your colors in Spanish — think las hojas rojas del otoño (the red autumn leaves).

Where Do the Spanish Month Names Come From?

Understanding the origin of each word makes it far easier to remember — and it explains why Spanish and English months look so similar. Both languages inherited the calendar from the Romans.

• enero comes from Ianuarius, honoring Janus, the two-faced god of beginnings and doorways.
• marzo is named for Mars, the god of war.
• junio honors the goddess Juno.
• julio was renamed for Julius Caesar, and agosto for the emperor Augustus.
• septiembre through diciembre are simply the Latin words for seven, eight, nine, and ten — a leftover from an older ten-month Roman calendar.

That last fact is a fun memory hook: diciembre shares a root with “decimal” and “December,” both pointing back to the number ten.

Example Sentences Using the Months

Vocabulary sticks best when you see it in action. Read these aloud and swap in your own details:

• Mi cumpleaños es el 12 de febrero. — My birthday is on February 12th.
• En agosto vamos a la playa todos los años. — In August we go to the beach every year.
• El nuevo curso empieza en septiembre. — The new course starts in September.
• Diciembre es el mes de las fiestas. — December is the month of celebrations.
• ¿En qué mes naciste? — Nací en mayo. — In which month were you born? — I was born in May.

Memory Tips to Learn the Months Fast

Twelve words can feel like a lot at first, but these strategies will lock them into your memory quickly:

1. Group by similarity to English

Split the list into “obvious” months and “tricky” ones. Abril, mayo, septiembre, octubre, noviembre, diciembre are nearly identical to English, so learn them first for a quick confidence boost. Then focus your energy on the four that change more: enero, marzo, junio, julio.

2. Anchor each month to a real event

Attach months to dates you already care about — your birthday, a holiday, a family member’s anniversary. Enero = New Year, julio = summer vacation, diciembre = Christmas. Emotional anchors are far stronger than rote lists.

3. Say them in a rhythm or song

Chant the twelve months out loud in order, three times a day, tapping a beat. The steady syllable rhythm of Spanish makes them almost musical, and hearing your own voice builds pronunciation muscle memory.

4. Use the calendar you already have

Change your phone’s language to Spanish, or relabel a paper calendar. Every time you check a date, you get a free, no-effort review. This kind of “little and often” exposure is exactly the habit we recommend to anyone serious about learning the language.

5. Practice with connected vocabulary

Learn the months alongside related building blocks — numbers for the dates, seasons for context, and pointing words like Spanish demonstrative adjectives (este mes = this month, ese año = that year). Connected learning always beats memorizing in isolation.

A Quick Cross-Language Bonus

If you are curious about how much of this transfers to other Romance languages, take a look at the months in Italian. Because both come from Latin, you will spot gennaio/enero, marzo/marzo, and dicembre/diciembre lining up almost perfectly — proof that every language you learn makes the next one easier.

Start Speaking Spanish with Confidence

You now know all twelve months, how to pronounce them, why they stay lowercase, how to write dates, which preposition to use, and how the seasons fit in. The next step is simply using them out loud with someone who can guide you. A tutor can correct your pronunciation of junio and marzo in real time and help you turn vocabulary into real conversation.

Frequently Asked Questions

Are the months of the year capitalized in Spanish?

No. In Spanish the months are written entirely in lowercase — enero, febrero, marzo — because they are treated as common nouns. The only exception is when a month begins a sentence, in which case normal capitalization rules apply. This is different from English, where every month is always capitalized.

Are the Spanish months masculine or feminine?

All twelve months are grammatically masculine, so they take the article el and masculine adjectives — for example, un enero lluvioso (a rainy January) or el próximo diciembre (next December).

How do you write the date in Spanish?

Use the formula el + day + de + month + de + year, with the day before the month. For example, October 3, 2025 is written el 3 de octubre de 2025 and read as “el tres de octubre de dos mil veinticinco.”

Which preposition means “in” a month?

Use en with no article: en abril (in April), en septiembre (in September). You may also hear the longer, more formal en el mes de abril, but en + month is the everyday choice.

Why do Spanish and English months look so similar?

Both calendars descend from Latin and the Roman system, so the names share the same roots — Roman gods (Janus, Mars, Juno), emperors (Julius, Augustus), and Latin numbers (September to December). That shared origin is exactly why the months are one of the easiest topics for English speakers to learn.

What is the fastest way to memorize the months in Spanish?

Learn the six that resemble English first, anchor each remaining month to a personal date or holiday, and review daily by switching your phone or calendar to Spanish. Practicing them out loud with a tutor cements both the order and the pronunciation.
