What Is Your Birthday in Spanish | Dates And Phrases Guide

To ask “what is your birthday” in Spanish, say “¿Cuándo es tu cumpleaños?”, and respond with “Mi cumpleaños es el [day] de [month].”

Learning how to talk about dates opens up many conversations. You might want to celebrate a friend or fill out a form correctly while traveling. This guide breaks down the grammar, vocabulary, and cultural nuances so you never miss a special date.

We will cover the months, the numbers, and the specific sentence structures used by native speakers. You will also find tips on pronunciation to help you sound natural.

The Core Question: How To Ask For A Birthday

The most direct translation of “when is your birthday” depends on who you are talking to. Spanish distinguishes between formal and informal “you,” which changes the verb conjugation and the possessive adjective.

Informal Settings

Use this version with friends, family, children, or people your own age. It implies a level of closeness and comfort.

  • Say “¿Cuándo es tu cumpleaños?” — This is the standard way to ask “When is your birthday?” using the informal “tu.”
  • Say “¿Cuándo cumples años?” — This translates roughly to “When do you turn years?” or “When do you complete years?” It is very common in casual conversation.

Formal Settings

Use these variations with elders, authority figures, or people you do not know well. It shows respect and politeness.

  • Say “¿Cuándo es su cumpleaños?” — The “su” indicates the formal “usted.”
  • Say “¿Cuál es su fecha de nacimiento?” — This means “What is your birth date?” You will hear this in administrative settings, like at a doctor’s office or immigration desk.

If you are addressing a group, the phrasing changes again. You would ask “¿Cuándo es el cumpleaños de ustedes?” in Latin America, or “¿Cuándo es vuestro cumpleaños?” in Spain.

Responding To What Is Your Birthday in Spanish

Answering this question requires a specific formula. Unlike English, which often puts the month first (March 10th), Spanish consistently uses a Day-of-Month structure.

The formula is: El [Day] de [Month].

Use the definite article “el” before the number because “día” (day) is a masculine noun. Use the preposition “de” to connect the number to the month.

  • Correct Format — El cinco de mayo (May 5th).
  • Correct Format — El diez de agosto (August 10th).
  • Correct Format — El veinticinco de diciembre (December 25th).

You do not need to use ordinal numbers (first, second, third) for dates, with one major exception which we will discuss in the numbers section. For the most part, you simply use the standard counting numbers.

The Twelve Months In Spanish

You must know the months to complete your sentence. A vital rule in Spanish grammar is that months are not capitalized unless they appear at the start of a sentence. This differs from English where months are always proper nouns.

Winter and Spring Months

  • enero — January. Pronounced “eh-NEH-roh.”
  • febrero — February. Pronounced “feh-BREH-roh.”
  • marzo — March. Pronounced “MAR-soh” (Latin America) or “MAR-thoh” (Spain).
  • abril — April. Pronounced “ah-BREEL.”
  • mayo — May. Pronounced “MAH-yoh.”
  • junio — June. Pronounced “HOO-nyoh.”

Summer and Autumn Months

  • julio — July. Pronounced “HOO-lyoh.”
  • agosto — August. Pronounced “ah-GOS-toh.”
  • septiembre — September. Pronounced “sep-TYEM-breh.”
  • octubre — October. Pronounced “ok-TOO-breh.”
  • noviembre — November. Pronounced “noh-VYEM-breh.”
  • diciembre — December. Pronounced “dee-SYEM-breh.”

Memorizing these allows you to quickly recognize dates when reading or listening. Practice saying them aloud to get comfortable with the vowel sounds, which are shorter and crisper than in English.

Using Numbers For Dates Correctly

Answering what is your birthday in Spanish requires familiarizing yourself with the numbers 1 through 31. Most dates use cardinal numbers (one, two, three) rather than ordinal numbers (first, second, third).

The First Of The Month Exception

The first day of any month is the only time you must use an ordinal number. You never say “el uno de…” for a date.

  • Say “El primero” — Use this for day one. Example: “Mi cumpleaños es el primero de enero” (My birthday is January 1st).

Numbers 2 through 31

For every other day, use the standard number. Here is a reference list for the days of the month.

Number Spanish Word Pronunciation Tip
1 primero pree-MEH-roh
2 dos dohs
3 tres trehs
4 cuatro KWAH-troh
5 cinco SEEN-koh
10 diez dyehs
15 quince KEEN-seh
20 veinte BAYN-teh
21 veintiuno bayn-tee-OO-noh
30 treinta TRAYN-tah
31 treinta y uno TRAYN-tah ee OO-noh

Notice that numbers 16 through 29 are often written as one word (e.g., dieciséis, veintidós), while numbers from 30 onwards use “y” to separate the tens and ones (e.g., treinta y uno).

Adding The Year To Your Answer

Sometimes you need to provide your full date of birth, including the year. This format simply extends the phrase we already built.

Structure: El [Day] de [Month] de [Year].

For years after 2000, you read the full number. For example, 2005 is “dos mil cinco.” For years in the 1900s, you also read the full number, unlike English where we often split it (nineteen-ninety). The year 1990 is “mil novecientos noventa.”

  • State the full phrase — Mi fecha de nacimiento es el cuatro de julio de mil novecientos ochenta (July 4, 1980).
  • Use “del” occasionally — In some regions, or for years prior to 2000, you might hear “del” instead of “de” before the year, but “de” is standard and widely accepted everywhere.

Understanding Written Date Formats

Visualizing the date is important if you are filling out forms. Most Spanish-speaking countries follow the logical progression of time: smallest unit to largest unit.

Day-Month-Year Order

If you see a form asking for your birth date (fecha de nacimiento), and you write 03/05/1995, a Spanish speaker will read this as May 3rd, not March 5th.

  • Check the order — Always write Day / Month / Year (DD/MM/AAAA). “AAAA” stands for “Año” (Year).
  • Look for separators — While slashes are common, some formal documents use dots or hyphens.

This difference causes confusion for travelers from the United States. Always double-check the column headers on arrival cards or hotel registrations to ensure you put the day and month in the right boxes.

Common Birthday Vocabulary And Wishes

Once you establish the date, the conversation usually moves to celebration. Knowing the right vocabulary helps you participate in the festivities.

Happy Birthday Phrases

You have a few options to wish someone well. The choice depends on the region and your relationship with the person.

  • Wish “¡Feliz cumpleaños!” — The most standard “Happy Birthday.” It works in every country and every situation.
  • Wish “¡Felicidades!” — Literally “Congratulations.” You can use this for birthdays, anniversaries, or promotions.
  • Wish “¡Que cumplas muchos más!” — This means “May you turn many more.” It is a warm, common addition to a birthday greeting.

Party Terms

If you are invited to a celebration, you should recognize these words.

  • La fiesta — The party.
  • El pastel / La torta — The cake. (Usage varies by country; Mexico often uses pastel, while South America often uses torta).
  • Las velas — The candles.
  • El regalo — The gift.

Cultural Traditions To Know

Birthdays in Hispanic cultures often involve more than just cake and gifts. Several traditions might surprise you if you are not prepared.

La Mordida

In Mexico and parts of Central America, after singing “Las Mañanitas” (the traditional birthday song), guests may chant “¡Mordida! ¡Mordida!” This signals that the birthday person must take a bite of the cake without using their hands. Usually, a family member will playfully push their face into the icing.

The Quinceañera

The 15th birthday for girls is a monumental event known as the quinceañera. It marks the transition from childhood to womanhood and is often celebrated with a large party, a formal dress, and a religious ceremony. It is much more significant than a “Sweet 16.”

Ear Pulling

In Spain (and occasionally other regions), it is traditional to gently pull the birthday person’s ears—one pull for each year of age. It is a playful gesture meant to wish the person long life and wisdom.

Avoiding Common Mistakes

Learners often carry English habits into Spanish. Avoiding these small errors will polish your speaking and writing.

  • Do not capitalize months — Writing “Enero” in the middle of a sentence marks you as a beginner. Keep it lowercase: “enero.”
  • Do not mix “ser” and “tener” — When discussing age, Spanish uses the verb “tener” (to have). You say “Tengo 20 años” (I have 20 years), never “Soy 20.” However, for the birthday date itself, you use “ser” (Es el 5 de mayo).
  • Do not forget the “el” — You cannot say “Mi cumpleaños es 5 de mayo.” You must include the article: “es el 5 de mayo.”

Practice Sentences For Daily Use

Rehearsing these full sentences will help lock the grammar into your mind. Try substituting your own information.

  • State “Nací el dos de febrero.” — “I was born on February 2nd.”
  • Ask “¿Qué día es tu cumpleaños?” — “What day is your birthday?” (A variation focusing on the day).
  • State “Su fiesta es el sábado.” — “His/Her party is on Saturday.”

Mastering these phrases ensures you can build friendships and navigate social situations with ease. The structure is consistent, so once you learn the numbers and months, you are set.

Frequently Asked Questions

How do you say “I was born in” in Spanish?

To say “I was born,” use the phrase “Yo nací.” You can follow this with the year, month, or specific date. For example, “Yo nací en 1990” (I was born in 1990) or “Nací el 3 de octubre” (I was born on October 3rd).

Why do Spanish speakers say “cumpleaños”?

The word “cumpleaños” is a compound noun. It comes from the verb “cumplir” (to complete or turn) and “años” (years). So, the word literally means “completing years.” It is singular and plural; one birthday is “un cumpleaños,” and two are “dos cumpleaños.”

Do you use ordinal numbers for dates in Spanish?

Generally, no. Unlike English speakers who say “May fourth,” Spanish speakers say “cuatro de mayo” (four of May). The only exception is the first day of the month, which is always “el primero” (the first), never “el uno.”

What is the “Saint’s Day” tradition?

In many Hispanic countries, people celebrate their “Día del Santo” in addition to their birthday. This corresponds to the Catholic saint associated with that specific day on the calendar. Some people are even named after the saint of the day they were born.

How do you ask someone’s age politely?

The standard question is “¿Cuántos años tienes?” (informal) or “¿Cuántos años tiene usted?” (formal). This literally translates to “How many years do you have?” Remember to answer with “Tengo [number] años,” not “Soy [number].”

Wrapping It Up – What Is Your Birthday in Spanish
