Say your birthday as “Mi cumpleaños es el 12 de mayo,” with el before the day and de before the month.
If you came here to learn How To Say The Date Of Your Birthday In Spanish, the main pattern is short and friendly: Mi cumpleaños es el + day + de + month. The day is a number, the month is said in Spanish, and the word de ties them together.
That gives you lines like Mi cumpleaños es el 12 de mayo and Nací el 3 de octubre. Once you know that rhythm, you can say your birthday in class, on a form, during small talk, or in a Spanish lesson without freezing.
Birthday Dates In Spanish Start With El
Spanish birthday dates usually take el before the day. Think of it as “on the,” not as a word you translate one by one. English says “my birthday is May 12,” but Spanish says the date in a day-first order: “my birthday is the 12 of May.”
The Core Pattern
The safest speaking pattern is:
- Mi cumpleaños es el 12 de mayo. My birthday is May 12.
- Nací el 12 de mayo. I was born on May 12.
- Mi fecha de nacimiento es el 12 de mayo de 1998. My date of birth is May 12, 1998.
For casual talk, mi cumpleaños es… sounds warm and normal. For paperwork, mi fecha de nacimiento es… fits better. For a short personal sentence, nací… is clean and direct.
Month Names Stay Lowercase
Spanish month names are not capitalized unless they begin a sentence or appear in a title. Write mayo, not Mayo, inside a normal sentence. The same rule applies to enero, febrero, julio, and the rest.
Here are the months you’ll need: enero, febrero, marzo, abril, mayo, junio, julio, agosto, septiembre, octubre, noviembre, diciembre. Say them after de, and your birthday line will already sound far more natural.
Saying Your Birthday Date In Spanish With Natural Wording
Most learners get the words right but place them in an English order. Spanish usually puts the day before the month: el 9 de abril, not abril 9. The order is part of why the sentence sounds Spanish instead of copied from English.
Formal And Casual Lines
Pick the line that matches the setting. In a friendly chat, you don’t need the year. In a school record, visa form, medical intake, or ID question, the year may be needed.
- Casual:Mi cumpleaños es el 7 de agosto.
- Personal:Nací el 7 de agosto.
- Form style:Mi fecha de nacimiento es el 7 de agosto de 2001.
- Question:¿Cuándo es tu cumpleaños?
- Answer:Es el 7 de agosto.
What To Do With The First Day
For the first day of a month, Spanish gives you two accepted choices: el primero de enero and el uno de enero. In much of Latin America, primero is common. In Spain, uno is often heard. For day 2 through day 31, use regular numbers: el dos, el quince, el treinta y uno.

How The Written Date Should Read
For written Spanish, the usual order is day, month, year: 14 de junio de 1999. The RAE date writing entry explains the date pattern with de between the day, month, and year.
The RAE date expression notes also show the day-month-year order as the traditional choice in Spanish-speaking countries. That matters when your birthday appears in a sentence, on a card, or in a profile.
Numbers, Words, And Slashes
In a sentence, the clearest style is 14 de junio de 1999. On a form, you may see numbers: 14/06/1999. Be careful with slashes if you’re used to month-first dates. In many Spanish-speaking places, 06/07/1999 means 6 July, not June 7.
When speaking, don’t say the slash format out loud. Turn it back into words: el seis de julio de mil novecientos noventa y nueve. If the year feels too long, you can leave it out in casual talk.
When The Year Matters
For birthdays, the year is private in many casual settings. You can say mi cumpleaños es el 22 de noviembre and stop there. For date of birth, the year belongs in the answer: mi fecha de nacimiento es el 22 de noviembre de 2004.
For January 1, the RAE answer on primero and uno says both forms are valid for the first day of a month. After the first day, stick with cardinal numbers.
Birthday Date Mistakes That Make Spanish Sound Off
Small changes can make the sentence feel stiff or foreign. The fixes are easy once you spot the pattern.
| Common Slip | Better Spanish | Why It Works |
|---|---|---|
| Mi cumpleaños es mayo 12. | Mi cumpleaños es el 12 de mayo. | Spanish usually puts day before month. |
| Mi cumpleaños es 12 de mayo. | Mi cumpleaños es el 12 de mayo. | El makes the date sound complete. |
| Mi cumpleaños es el doce Mayo. | Mi cumpleaños es el 12 de mayo. | Months stay lowercase in normal sentences. |
| El segundo de enero for January 2 | El dos de enero | After day one, Spanish uses cardinal numbers. |
| Mi cumpleaños está… | Mi cumpleaños es… | Ser fits fixed calendar dates. |
Practice Lines You Can Swap In
Now plug in your own date. Say the line slowly once, then say it again at normal speed. The goal is a sentence you can answer with right away.

Final Check Before You Say It
Before you answer, run this short check in your head: el, then the day, then de, then the month. Add de plus the year only when the setting asks for your date of birth.
So the clean answer is: Mi cumpleaños es el 12 de mayo. For a fuller personal line, say: Nací el 12 de mayo de 1998. Once that pattern clicks, you can handle nearly any birthday date in Spanish with ease.
