How to connect Portuguese numbers, dates, and time expressions

Introduction

Connecting numbers, dates, and time expressions in Brazilian Portuguese is essential for daily tasks: booking appointments, reading timetables, telling age, or understanding receipts. This article guides complete beginners through pronunciation, grammar, and practical phrases so you can recognize and produce common combinations confidently.

Why connecting numbers, dates, and time matters

Numbers, dates, and time appear together in many real-life situations: reservas de hotel, horários de ônibus, mensagens de texto, and appointment confirmations. Learning how they interact helps you avoid misunderstandings and appear more natural when speaking.

Basic Portuguese numbers you must know

Learn these core numbers in Brazilian Portuguese. The first appearance of each number uses strong formatting.

um – one

dois – two

três – three

quatro – four

cinco – five

dez – ten

vinte – twenty

trinta – thirty

cem – one hundred

mil – one thousand

Common patterns for writing and saying dates

Brazilian Portuguese typically uses the day-month-year order, for example 02/07/2026 means 2 July 2026. When speaking, use the preposition em or no/na, and month names are not capitalized.

2 de julho de 2026 – 2 July 2026
2 de julho de 2026

Month names beginners should memorize:

janeiro, fevereiro, março, abril, maio, junho, julho, agosto, setembro, outubro, novembro, dezembro

Examples you might see on schedules or tickets:

Válido até 15 de agosto de 2026 – Valid until August 15, 2026
Válido até 15 de agosto de 2026

Evento: 30 de novembro – Event: November 30
Evento: 30 de novembro

How to say time: 24-hour and 12-hour formats

In formal contexts like transportation timetables, Brazil often uses the 24-hour clock. In everyday speech, the 12-hour clock with de manhã, da tarde, and da noite is common.

Key expressions:

meia-noite – midnight

meio-dia – noon

da manhã – in the morning (use with 1:00–11:59)

da tarde – in the afternoon (use with 12:00–17:59)

da noite – at night (use with 18:00–23:59)

Examples on a departure board:

Saída 14:30 – Departure 14:30 (2:30 PM)
Saída 14:30

Examples in casual speech:

Encontro às 9 da manhã – Meeting at 9 in the morning
Encontro às 9 da manhã

Linking numbers with nouns: gender and plural

Numbers affect the nouns that accompany them. The word for one changes depending on gender: use um before masculine nouns and uma before feminine nouns. For quantities above one, the noun is plural.

um bilhete – one ticket
um bilhete

uma reserva – one reservation
uma reserva

dois ingressos – two tickets
dois ingressos

Beginner tip: memorize common countable items with their gender (o bilhete, a reserva) and practice saying numbers with them.

Connecting numbers and dates: prepositions and formats

When giving a date in speech, use the preposition de between day, month, and year. When writing numeric dates, Brazil uses day/month/year.

Spoken pattern: dia + de + mês + de + ano

Hoje é 5 de maio de 2026 – Today is May 5, 2026
Hoje é 5 de maio de 2026

On forms you may see:

Data de nascimento: 12/03/1990 – Date of birth: 12/03/1990
Data de nascimento: 12/03/1990

Saying exact times: use de and às

To say at a particular hour use às before the time; to say during a period use de … a … (from … to …).

A reunião é às 15:00 – The meeting is at 3:00 PM
A reunião é às 15:00

O curso vai de 10:00 a 12:00 – The course goes from 10:00 to 12:00
O curso vai de 10:00 a 12:00

Note: use da manhã/da tarde/da noite when using 12-hour times: às 7 da noite (at 7 PM).

Minutes and common connectors

To express minutes past the hour, use e; for minutes to the hour, use menos. For quarters and halves, use quarto and meia.

São 3 e 15 or São 3 e quinze – It is 3:15
São 3 e 15

São 4 e meia – It is 4:30 (literally 4 and a half)
São 4 e meia

Faltam 10 para as 5 – It is 4:50 (literally 10 to 5)
Faltam 10 para as 5

Beginner tip: when you see digital times on phones or signs, translate mentally into e/minutes or menos to practice spoken forms.

Dates in spoken questions and answers

Common question words you will use with dates and times:

Quando? – When?

Que dia? – What day?

Que horas? – What time?

Sample dialogues:

Quando é o voo?
É no dia 8 de setembro, às 6 da manhã.
Quando é o voo?
É no dia 8 de setembro, às 6 da manhã.

Que horas começa a aula?
Começa às 18:30.
Que horas começa a aula?
Começa às 18:30.

Using ordinal numbers for dates and sequences

Ordinal numbers are used in spoken and written Portuguese for first, second, etc. For dates, Brazilians usually say cardinal numbers for day and year, but you will hear ordinals in formal contexts.

primeiro – first (used in dates: primeiro de maio for May 1; many speakers also say um de maio)

Example:

O contrato começa no primeiro de junho – The contract starts on June first
O contrato começa no primeiro de junho

Common mistakes beginners make (and how to avoid them)

Mistake 1: Mixing 12-hour and 24-hour when speaking. Fix: when in doubt, use da manhã/da tarde/da noite with 12-hour speech or the numeric 24-hour in formal written contexts.

Mistake 2: Forgetting gender agreement after números. Fix: learn the noun gender with the noun and practice simple phrases like um carro, uma passagem.

Mistake 3: Translating word-for-word from English order. Fix: remember Portuguese date order is day-month-year and practice reading dates visually: 05/08 is 5 August.

Practical exercises for beginners

Exercise 1: Read timetables. Find a bus or flight schedule and say each time aloud using da manhã/da tarde/da noite.

Exercise 2: Write simple appointments. Create 10 sample appointments using day + de + month + de + year and time with às.

Exercise 3: Roleplay booking. Practice a short call: say your date of birth, request a reservation date, and confirm the time using the patterns shown below.

Roleplay sample:

Olá, quero reservar uma mesa para duas pessoas no dia 12 de julho às 20 horas.
Olá, quero reservar uma mesa para duas pessoas no dia 12 de julho às 20 horas.

Useful vocabulary and short phrases to memorize

hoje – today

amanhã – tomorrow

ontem – yesterday

dia – day

semana – week

mês – month

ano – year

às – at (used before clock times)

de – of, used in dates (5 de junho)
