Portuguese month basics with dates and birthdays

Introduction

Learning the months, dates, and how to talk about birthdays is one of the most practical first steps when studying Brazilian Portuguese. This article gives beginner-friendly vocabulary, sample sentences, pronunciation hints, and realistic examples you can use in everyday situations like filling forms, making plans, reading calendars, or wishing someone feliz aniversário.

Portuguese month names and pronunciation

In Brazilian Portuguese the months are similar to English but with Portuguese pronunciation. Learning the written form and a simple pronunciation guide helps you read dates and understand spoken Portuguese on schedules, tickets, and messages.

janeiro — January (zha-NEH-ro)

fevereiro — February (feh-VEH-ray-ro)

março — March (MAR-soo)

abril — April (ah-BREEL)

maio — May (MY-oh)

junho — June (ZHOON-yo)

julho — July (ZHOOL-yo)

agosto — August (ah-GOHS-too)

setembro — September (seh-TEM-broo)

outubro — October (oh-TOO-broo)

novembro — November (noh-VEM-broo)

dezembro — December (deh-ZEM-broo)

Pronunciation tips

Brazilian Portuguese pronunciation often uses open vowel sounds. Focus on clear syllable stress: many month names stress the second syllable, like fevereiro and setembro. The letters ç and j have distinct sounds: ç is an s sound as in março, and j is a soft zh sound as in junho.

How to say dates in Brazilian Portuguese

There are two common ways to say dates: the full spoken form and the numeric form for forms or tickets.

Spoken full form

The usual spoken structure is day de month de year. Example: 15 de março de 1990.

15 de março de 1990 — quinze de março de mil novecentos e noventa

Beginners can start by saying day de month. For example:

Hoje é 7 de abril — Today is April 7

Meu voo é 23 de julho — My flight is July 23

Numeric and formal forms (useful on forms)

Brazil commonly uses day/month/year format. You will see dates like 07/04/2026 or 7/4/2026. On official forms write day/month/year: 07/04/2026.

When filling online forms follow the displayed format. Example on a ticket: Data: 12/11/2026.

Talking about birthdays and age

Birthday vocabulary is essential for social interactions. Here are the core words and phrases you will use often.

aniversário — birthday

parabéns — congratulations; used to say happy birthday

idade — age

fazer anos — to turn (a certain age). This expression is common in Brazilian Portuguese.

Common birthday phrases

Use these short phrases in conversations, messages, or cards.

Feliz aniversário — Happy birthday

Muitos parabéns — Congratulations (less common in Brazil but understood)

Parabéns pelo seu aniversário — Congratulations on your birthday

Quantos anos você faz? — How old are you turning?

Eu faço 25 anos amanhã — I turn 25 tomorrow

Sample birthday dialogues

Simple, realistic dialogs help beginners practice everyday usage.

Person A: Hoje é seu aniversário?
Person B: Sim, faço 30 anos hoje.

Person A: Parabéns! Vamos comemorar no sábado.
Person B: Obrigado! A festa é dia 12 de junho.

Practical examples: invites, cards, and messages

Below are short, clear examples you can copy when writing invitations, messages, or social media posts in Brazilian Portuguese. These are typical and beginner-friendly.

Mensagem curta para WhatsApp: Feliz aniversário! Que seu dia seja especial.

Convite simples: Você está convidado para minha festa de aniversário no dia 20 de setembro às 19h.

Mensagem de confirmação: Confirmo presença na festa dia 20/09.

Examples for forms, IDs, and schedules

What you often need to understand or write in real life: birthdate fields and schedules.

Nascimento: 03/05/1998 — Date of birth field format on a form.

Data e hora: 14/08/2026, 10:00 — Useful on appointment cards or schedules.

Horário: atendimento a partir de 09:00 — Opening hours seen on signs.

Grammar basics for dates and birthdays

Here are a few simple grammar rules to make your sentences correct and natural.

Use of de for dates

When speaking full dates you use de between day and month and between month and year: 2 de maio de 2001. Beginners often forget the second de — include both for natural speech.

Numbers for days

Days are usually said as cardinal numbers, not ordinals. Say 1º de janeiro on written invitations sometimes, but in speech 1 de janeiro is fine. Example: primeiro de maio is used for holidays like Dia do Trabalho, but for birthdays you can say primeiro de maio or um de maio.

Gender of months

Months are masculine in Portuguese. When using articles you say o mês de março or no mês de março. However beginners can skip articles and simply use de + month: dia 10 de março.

Beginner tips and common mistakes

These practical tips help avoid frequent errors and accelerate comprehension in real contexts.

Tip 1: Memorize the written month names first. Reading calendars and schedules will become faster.

Tip 2: Practice day/month order. English speakers often mix month/day with Portuguese forms — remember Brazil uses day/month/year.

Tip 3: Use de between parts of a full date. Saying 12 março 1995 sounds unnatural and could confuse listeners.

Tip 4: Pay attention to pronunciation of ç and j. Practice with março, junho, and julho.

Tip 5: For birthdays, use fazer anos to say turning an age. Saying Eu tenho 30 anos means I am 30; Eu faço 30 anos means I turn 30.

Common beginner mistakes

Mistake: Writing dates as month/day. Correction: Use day/month in Brazil.

Mistake: Omitting de between month and year. Correction: Say 5 de maio de 2005 for clarity.

Mistake: Mixing European spellings or pronunciations. Correction: Use Brazilian forms like junho, not European variants.

Short practice exercises

Try these beginner exercises to build confidence. Write answers in Brazilian Portuguese using the patterns above.

Exercise 1: Write your birthday in the day de month de year format. Example: Meu aniversário é 9 de outubro de 1992.

Exercise 2: Compose a short invite: include date, time, and address. Example: Festa dia 18 de dezembro às 20h, na minha casa.

Exercise 3: Translate this into Portuguese: My appointment is on March 3 at 14:00. (Answer: Meu compromisso é dia 3 de março às 14:00.)
