Learning the months in Spanish takes about ten minutes — and then one small rule trips up almost every beginner for years afterwards. Spanish months look reassuringly close to their English cousins (enero, marzo, septiembre), which is exactly why people write them the way they write English months, with a capital letter. In Spanish that is simply wrong.
This guide gives you all 12 months with audio you can play, the capitalisation rule nobody teaches early enough, how to write and say a full date like el 15 de marzo de 2026, and the handful of phrases you actually need to talk about when something happens. Everything here is what a tutor would cover in a first lesson on dates — no filler.
📅 The 12 Months in Spanish
Tap the audio on each row and repeat it out loud. Saying it once beats reading it five times.
Notes
Three sounds to watch: the j in junio and julio is a throaty h, never an English j. The z in marzo is an s across Latin America and a soft th in most of Spain. And septiembre is often shortened to setiembre in speech — both spellings are accepted.
🔠 The One Mistake Almost Every Learner Makes
Spanish months are never capitalised. Neither are the days of the week, the seasons, or nationalities. A month only takes a capital letter when it starts a sentence or belongs to a proper name.
The exceptions are names, not months: el 1 de Mayo as the name of the holiday, la Revolución de Octubre, Enero as a surname. If it is a date, keep it lowercase.
Important
If you remember one thing from this page, make it this: lowercase. It is the single fastest way to make your written Spanish look like a native wrote it.

🗓️ How to Write and Say a Full Date
Spanish dates run from smallest to largest: day, then month, then year, glued together with de.
Example
el 15 de marzo de 2026 — the 15th of March, 2026
Listen to it:
The pattern never changes:
el + [number] + de + [month] + de + [year]
Four details that save you from sounding foreign:
- Use plain numbers, not ordinals. English says the fifth of June; Spanish says el cinco de junio. The only ordinal you will hear is el primero for the 1st, and in Spain even that is usually el uno.
- No preposition before the day. El 15 de marzo, never en el 15 de marzo.
- Short form is day-first: 15/03/2026 means 15 March, not 3 December. This bites travellers booking flights.
- Asking the date: — what's today's date? The answer starts with Hoy es...

🔢 Saying When Something Happens
Once you have the months, these are the phrases that make them useful in a real conversation.
Note that en does the job of both in and on here — there is no Spanish equivalent of the English fuss between in March and on March 3rd.
❄️ Months and Seasons
The four seasons are also lowercase, and they flip depending on which hemisphere you are talking about — worth remembering before you tell someone in Buenos Aires that July is summer.
In Argentina, Chile, Uruguay and Peru those blocks are reversed. En julio hace frío is a perfectly normal sentence in Santiago.

🧠 Three Tricks to Remember All 12
- Nine of the twelve are near-identical to English. Enero, febrero, marzo, abril, mayo, junio, julio, agosto — you already know them. Only the -iembre and -ubre endings need attention.
- Learn the four -bre months as one block. Septiembre, octubre, noviembre, diciembre all end the same way and all fall at the end of the year. Chant them together.
- Anchor them to your own life. Say your birthday, your holidays and your rent day out loud in Spanish. Dates you actually use stick; dates on a list do not.
🎯 The Part a List Cannot Do
Reading a table of months is the easy half. The hard half is producing el veintitrés de septiembre at conversational speed when someone asks when your flight lands — and that only comes from saying it, being corrected, and saying it again.
That is exactly what Umi, our AI Spanish tutor, does. You talk, Umi listens, corrects your pronunciation and pushes you until dates come out automatically. It is available whenever you have ten minutes, it never sighs at the fourth attempt, and it starts with a 14-day free trial, 30 minutes a day.
